Interesting Facts About Godzilla and Kong

Godzilla's movements and behaviour — notably the scene in which he lies curled up asleep within the Roman Colosseum — were modelled on director Adam Wingard's cat, Mischief.

Ahead of its release, Takashi Yamazaki, who wrote and directed the acclaimed Godzilla Minus One (2023), helped publicise the picture by seeing it in advance and posting about it on social media: "I was able to watch the big movie early! It is super fun and gorgeous. Be sure to watch it on the big screen." Toho also prominently featured Yamazaki in adverts to promote the film in Japan, encouraging Japanese audiences to see it, although the film ultimately recorded the lowest attendance so far for the Monsterverse — 1.17 million viewers. This continues a trend in the Monsterverse of declining audience figures with each subsequent instalment released in Japan.

The image used as the blueprint for the B.E.A.S.T. Glove is the arm of the Pacific Rim (2013) Jaeger, Gipsy Danger. According to director Adam Wingard, the B.E.A.S.T. Glove was devised to boost Kong toy sales, and this also tied into the 1980s toy influence Wingard sought for the film.

According to director Adam Wingard, Skar King symbolises a scaled-up version of humanity's worst aspects, while Kong embodies its best qualities.

The shift in colour of Godzilla's atomic breath from light blue to a pink hue, indicating a complete surge in power, mirrors the Heisei series incarnation gaining the much more destructive Red Spiral Ray, since the sheer force of that attack exceeds his standard blue-coloured atomic breath. In the Heisei series, Godzilla was nearly defeated by Super Mechagodzilla after the machine destroyed Godzilla's second brain. Only when Fire-Rodan sacrificed his energy for Godzilla, at the urging of his adoptive brother Baby Godzilla, did Godzilla acquire the Red Spiral Ray and swiftly overcome Super Mechagodzilla. As in the Heisei series, Godzilla receives a power-up to face stronger foes — in this instance, Skar King and Shimo.

The film is due for release in 2024, precisely a decade after Godzilla (2014), the film which launched the Monsterverse franchise.

With a net budget of US$135 million, it is the least expensive entry in the MonsterVerse to date. Production was more efficient than on the previous instalment, Godzilla vs. Kong (2021), which saw numerous additional sequences filmed — including further character development, expanded lore and action set-pieces — that were ultimately removed from the released version. Director Adam Wingard also noted the team's greater experience with the visual-effects (VFX) workflow.

Director Adam Wingard presented the Mini-Kong to the studio as the Monsterverse's "Baby Yoda". The creature's name is never spoken in the film, but it is known as "Suko", a name first revealed through the toys and other merchandise. The name carries significance: when written phonetically in Japanese it can be split into two characters that together mean "Essential Child". Notably, Suko is typically a feminine name in Japanese and, perhaps by coincidence, is a Filipino word meaning "surrender".

According to director Adam Wingard, he considers Kong, rather than Godzilla, to be the true protagonist of the Monsterverse. While he is a fan of Godzilla, Wingard acknowledged that Kong is easier to empathise with, saying, 'You can't be as close to Godzilla as you can be to Kong.'

For Godzilla and Kong's new looks, Adam Wingard revealed: "Specifically, in the previous film I wanted Godzilla to keep continuity, to look the way he did in 'King of the Monsters' and the 2014 'Godzilla.' However, I didn't have the opportunity then to present my own take on Godzilla. So now I wanted to try different things with the spines and experiment with different colours. I didn't want it to be arbitrary; it is part of the story. And likewise, with Kong I wanted to give him a refreshed appearance too — we grew his beard out and added a bit more grey to his hair and so on."

Godzilla's new look includes purple/pink-coloured dorsal plates reminiscent of the MireGoji aesthetic from Godzilla 2000 (1999) and Godzilla vs. Megaguirus (2000), together with a pink atomic breath comparable to the violet beam in Shin Godzilla (2016). Creature designer Jared Krichevsky has also cited the plate design of Godzilla Ultima from Godzilla Singular Point (2021) as a direct source of inspiration.

For Dan Stevens's character, Trapper, director Adam Wingard wanted him to evoke the vibe of an 1980s action-figure and modelled him on the Chuckles character from the G.I. Joe toy line.

Godzilla has eight minutes of on-screen time, which, at the time of release, was the shortest of any MonsterVerse film. By comparison, that is three minutes fewer than Godzilla vs. Kong (2021) (11 minutes), and two minutes fewer than both Godzilla: King of the Monsters (2019) and Godzilla (2014), which each had 10 minutes. The MonsterVerse entry with the least on-screen time overall is Monarch: Legacy of Monsters (2023), amounting to four minutes across the entire season.

Regarding the colour palette, Adam Wingard explained: 'Whenever I was speaking with the visual artists, I said, "I want the film's colour scheme to capture the feeling of walking down a toy aisle in the 1980s, surrounded by ThunderCats, G.I. Joe and Transformers." It was an almost overwhelming rush — so many colours and textures. That's the energy I wanted to bring to this picture: a fresh, heightened reality. I wanted to see whether you could take that over-the-top toy-aisle experience and still find a way to root it in reality.'

Kong's glove is named the B.E.A.S.T., an acronym for Bio Enhanced Anatomech Seismic Thunder.

It is the third Monsterverse film featuring Kong to be shot in Australia, after Kong: Skull Island (2017) and Godzilla vs. Kong (2021).

The first MonsterVerse film to be shot in IMAX at a 1.90:1 aspect ratio for selected scenes.

When preparing the role of Trapper, Dan Stevens drew inspiration from Michael Douglas and Kurt Russell, particularly their performances in the films Romancing the Stone (1984) and Big Trouble in Little China (1986).

In an interview with CBR, director Adam Wingard revealed that the silent 'x' in the movie's title signifies a collaboration. He said it's a common practice for brands and businesses to use an 'x' when they join forces with artists. Wingard added that he was surprised, on reflection, that no one — as far as he knew — had ever used an 'x' in a title in this way before, explaining the mark comes from the shorthand of 'x' denoting a collaboration; for example, many shoe firms produce special partnerships with artists and the like.

Director Adam Wingard has said the film will not employ a dual storyline as the previous instalment did.

Kong's roaring stance while brandishing the B.E.A.S.T. Glove is reminiscent of the cover artwork for the fighting game Primal Rage (1994).

The trailer shows Godzilla emerging from an iceberg, much as he did in King Kong vs. Godzilla (1962).

Director Adam Wingard has said that toy adverts from the 1980s provided an additional source of inspiration for the film.

According to the film's official novelisation, Godzilla takes up residence in the Roman Colosseum because it reminds him of his former home, which was destroyed by a nuclear strike in Godzilla: King of the Monsters (2019), with a scientist even suggesting he has a 'soft spot' for humans.

Dan Stevens and Adam Wingard will team up again for the first time since The Guest (2014).

Adam Wingard is the first Monsterverse director to return for a second instalment, having previously directed Godzilla vs. Kong (2021).

According to director Adam Wingard, Elon Musk did, in fact, have some influence on the film. When the previous film was released, Musk tweeted that he thought it was 'amazeballs', while questioning the plausibility of a light-source existing in the Hollow Earth. Wingard has said the film's opening shot was included deliberately as a response to Musk's question, and he hoped Musk would appreciate it when he saw it.

Shimo is a Japanese term meaning "frost" or "grey hair." The name also translates as "hole" or "abyss" in Swahili. It was first unveiled on a Jada Toys Metalfigs figure at the 2023 Singapore Comic-Con.

The film's novelisation confirms that the Mini-Kong Suko is, in fact, Skar King's son.

One fan noticed the product placement and quickly tweeted, "Godzilla X Kong has this really funny scene where the human protagonist talks to her daughter outside her school and it suddenly cuts to the least subtle Volkswagen ad I've ever seen." The edit is so jarring because it looks as though it could have been lifted straight from a car advert, and it occurs during a fairly emotional moment in which Dr Ilene Andrews is attempting to comfort her adopted daughter Jia, who feels she doesn't fit in with her peers. Another viewer even superimposed a Volkswagen logo over the shot so others could see how incongruous it appeared.

The production was filmed under the working title: "Son of Kong."

Director Adam Wingard told Digital Spy that, although he felt there 'could be a place for her in the future', Madison simply did not fit the particular story he wanted to tell. He explained that his guiding principle while shaping the film was 'simplicity is key'. They intentionally reduced the number of characters so the audience could experience a more intimate journey with them. That is why the ensemble is fairly small on both the monster and human sides — giving more time to spend with each. While many of the MonsterVerse films feature a large cast, which has its merits, being five films in meant they needed to innovate and try things not seen before; even the structural approach to story and character was different. They wanted a more personal deep dive, and these were the characters that made the most sense for telling Kong's Hollow Earth story, which serves as the catalyst for everything.

It holds the record for featuring the greatest number of Titans in a MonsterVerse film — excluding stock footage — with at least nine appearing on screen.

To provide the cast with something to react to, Adam Wingard frequently ended up portraying either King Kong or Godzilla. The director explained: "I need to supply plenty of audio cues, so we normally run a large PA system. I usually have a microphone, and I'm either simply shouting 'Roar!' or actually producing a roar into the mic. Occasionally I have pre-recorded sound effects and I'll play those back to assist the performers." Wingard had to alter the technique for Kaylee Hottle, saying: "Usually, when you're filming sequences where performers must respond to something imaginary, you rely on verbal prompts, so we devised a system of off-screen lights that someone would trigger whenever I was cueing the actors. Sometimes people stood on ladders waving at Kaylee so she knew when to look. Everyone had to be synchronised and that becomes rather complicated."

Rebecca Hall, Brian Tyree Henry and Dan Stevens opened up about acting against CGI. Hall joked that often "you're staring at a cat laser on the wall and you're being very serious like this might kill you." Henry added that, without spoiling anything, there’s a moment in the film where Kaylee Hottle’s character Jia, who has a bond with Kong, is meant to reach out and touch his finger — but what you don’t see is someone lying on the floor holding a foam finger up on a pole, so the actors have to stay fully present to preserve the shot. Hall admitted she "finds a perverse pleasure in delivering extremely serious lines while apparently addressing a tennis ball on a stick" and said she laughed a lot when they called "cut." Stevens reckoned the sound work was "even harder" than the visual side, explaining that you have to react physically to noises even though you never hear the final IMAX sound on set — often someone off to one side will make the silliest "Wah!" instead of the real effect.

Adam Wingard regards Mothra as the most dignified monster in existence, and says that is why her return landed so well, explaining: "There's a moment in the film where you have Godzilla, Kong and Mothra together in front of the Sphinx, and sometimes when I watch the footage in the edit, I still think, 'I can't believe we managed to pack the frame with these three characters...' There are shots that feel like a dream for fans of the Showa era, where it's almost unbelievable that so much is happening in a single frame. The MonsterVerse is heading off in some wild and fun directions. The main antagonist in this film is really a kind of devilish figure. An alternate title might well be 'Kong Goes to Hell.' So if Kong is descending into hell and finds apes labouring down there under the devil, who is the Skar King, then Mothra is this very angelic spirit. That's how I approached her — very ethereal. She's a pure vessel within the MonsterVerse and acts as the great negotiator among the monsters. Everyone respects Mothra. She's the one creature I think the others will allow to get on with her business, and she's the only monster I believe Godzilla truly respects. He values her judgement. So if Mothra says, 'Listen, we need your help,' Godzilla will listen. Anything I say now wouldn't necessarily be canonical, so I don't want to pin down exactly what she is. I have my own thoughts about this version of Mothra, but I think it'll be more exciting to let that unfold, and I'm sure we'll explore it further."

As with Godzilla vs. Kong (2021), photographs of the toy line showing Godzilla's new look surfaced in November 2023 ahead of schedule, prompting divided reactions from fans over how gaunt it appeared. While some doubted their authenticity, an Empire article published on 2 December included images that lent them credibility, and the design was effectively confirmed later that day when official artwork of the revamp appeared on Legendary's merchandise store and the film's trailer was released. After the trailer's release, some viewers lamented that the on-screen Godzilla has pink dorsal plates, whereas the toy features red ones. Designer Jared Krichevsky reassured fans the redesign is temporary and that Godzilla will continue to evolve.

For Godzilla's pink form, Adam Wingard conceded that a touch of personal preference was involved. He admitted pink is his favourite colour, noting the editing suite where they cut the film was awash with pink lights, and that he generally keeps pink fairy lights in any room he occupies.

Suko, the Mini-Kong, is the third young ape to share the screen with Kong, following Kiko in Son of Kong (1933) and Baby Kong in King Kong Lives (1986).

The novel provides Shimo with far more background than the film. Monarch, having deduced her existence despite never having seen her, is aware of cave paintings that show her fighting and overpowering Godzilla. At one point Dr Andrews notes that the chemical makeup of her ice-based abilities matches the composition found in Ghidorah's frozen tomb in King of the Monsters, suggesting she was the one who encased him in ice.

Ahead of the film's release, many fans referred to Shimo as female, despite mixed information about whether the titan was male or female (creature designer Jared Krichevsky said he had no problem with people referring to Shimo as female). The question of Shimo's sex became a heated point of contention within the fandom when Amazon and Target's pages for the "Shimo with Frost Bite Blast" used female pronouns while other retailers employed male ones. Krichevsky initially commented that either option was acceptable but later used male pronouns for Shimo, which only stoked the debate further. The discussion was amplified by film news journalist and alleged leaker Timo Rose, known as KDM_Monsters on Twitter, who firmly insisted Shimo was male. It was eventually clarified that Shimo had originally been intended to be male, but was changed to female later in development.

Adam Wingard revealed that Lethal Weapon (1987) was an inspiration for the film.

A T-shirt distributed to the crew, illustrated by Christian Gonzalez, depicts a fossilised trilobite alongside the mysterious turtle-like bones from Mothra vs. Godzilla (1964).

The initial clash between Kong and Skar King drew inspiration from a sequence in the film Emperor of the North (1973), in which the characters A-No.-1 and Shack confront one another armed with a fire-axe and chains, respectively.

This represents Godzilla's fifth on-screen outing in the MonsterVerse, following Godzilla (2014), Godzilla: King of the Monsters (2019), Godzilla vs. Kong (2021) and Monarch: Legacy of Monsters (2023). Although he did not appear in Kong: Skull Island (2017), his roar is audible during the end credits.

Following the revelation of Shimo's ice-based abilities, it emerged that she was responsible for freezing King Ghidorah in Antarctica. Although the film's official limited-access guide to Godzilla: King of the Monsters (2019) led some fans to suspect this might not be the case, both the film and the novelisation confirm the retcon that Shimo was the one who froze King Ghidorah.

The initial concept for Shimo was simply an "ice Godzilla". Ultimately, Shimo’s finalised design closely resembles the Rhedosaurus from The Beast from 20,000 Fathoms (1953), which in turn inspired Godzilla (1954). In particular, she is a quadrupedal saurian with a single row of dorsal spines. Interestingly, the Rhedosaurus was also frozen in the Arctic. The main difference is that her skin is entirely white. She also shares features with Anguirus — being four‑legged, spike‑backed and bearing a crown of horns. There are similarities to Barugon from Gamera vs. Barugon (1966), including ice‑based powers akin to Barugon. Shimo’s colour scheme and the crystals on her back closely evoke Krystalak, a kaiju from the Godzilla video game Godzilla: Unleashed (2007). Her design, abilities and overall appearance likewise resemble a scrapped version of Anguirus from an early draft of Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack (2001), in which Anguirus might have possessed ice abilities.

Director Adam Wingard explained in an interview with the website Pinkvilla that the Skar King is a particularly compelling antagonist, describing him as something of an anti-Kong whose motives are rooted in recognisably human desires for power and control. Though not human, the Skar King’s actions echo themes of domination and ambition. Wingard said he is ape-like — able to think, feel and conspire — so his motivations are very much human, such as a hunger for power; effectively a super-dictator living in the Hollow Earth. He also revealed that the Skar King can perform all the feats Kong can, but with far greater agility, forcing Kong to adopt clever tactics in how he physically approaches him, and that the Skar King proves a formidable foe for both Godzilla and Kong, which is why they must team up to defeat him.

Brian Tyree Henry revealed what it was like to return to his role as podcaster Bernie, admitting he "hadn't expected just how much I'd be screaming" in the new film. He said: "I didn't realise Bernie would be really going through it in this one. I wasn't going through it on my own — I enjoyed the playful silliness I could bring to him. I liked that you get to see Bernie has aspirations, and you also see a little of his life. You could tell he was alone and that things didn't turn out the way he'd imagined. Because Dr Andrews believed in him and he was like, 'I should make a documentary', he realised Hollow Earth wasn't at all what he thought it was, but becoming part of a team, I think, became very important to him."

Kong's infected tooth was inspired by genuine tooth pain director Adam Wingard endured while directing his 2011 horror film You're Next. He has said he suffered a severe toothache throughout filming and into post-production; numerous visits to dentists failed to identify the cause until they eventually recommended surgery on his gums to stop the pain, and he spent all that time dealing with the toothache.

In Rome, graffiti depicts Hedorah's eye, Jet Jaguar's arm, an Xilien UFO, mysterious turtle-like bones, the Pacific Rim kaiju Knifehead and a symbol resembling Mothra's emblem alongside graffiti of Godzilla eating pizza. The phrase "Punch, Punch, Punch" appears above Jet Jaguar's arm, and the words "Save The " — cut off by the screen between Hedorah's eyes — can also be seen; these are references to the lyrics of the songs ''Godzilla and Jet Jaguar: Punch! Punch! Punch!'' and ''Save the Earth'' respectively.

As concept designer Jared Krichevsky notes, Skar King's whiplash is fashioned from the spine of a Warbat.

Although Adam Wingard publicised extensive monster set-pieces, many Monsterverse fans felt let down that these centred on Kong and the giant apes instead of Godzilla, with some comparing them to Planet of the Apes.

According to the novelisation, Kong encounters the Mini-Kong, Suko and the other Great Apes almost immediately after entering the subterranean realm because they had been lying in wait for him. After destroying the Monarch outpost, Skar King uncovered signs of another ape in Kong's cave and, intrigued, dispatched Suko's party to capture him.

A fan asked Dan Stevens how his character wound up as a kaiju dentist, and he outlined how the role came about: "I think he's had a bit of a chequered career. He was academically on a par with Dr Andrews back in the day, or at least they shared a few modules at university. We imagined his parents might have run a zoo. He would then set off around the globe on these adventurous trips. There are scarcely any jungles or deserts he hasn't visited. So very little fazes him, and he could transition to treating titanic-sized creatures quite easily. I suppose he's a cross between Steve Irwin and Bear Grylls, with a touch of Ace Ventura and Crocodile Dundee thrown in."

This represents Kong's fifth outing within the MonsterVerse, coming after Kong: Skull Island (2017), Godzilla vs. Kong (2021), Skull Island (2023), and Kong's cameo in the Monarch: Legacy of Monsters (2023) episode Beyond Logic (2024).

Brian Tyree Henry likened the film to Three Men and a Baby (1987), saying "I suppose we were simply glad that Kong is no longer on his own, that he's discovering a whole other side of himself he hadn't known, and finding a sense of belonging — in him taking on parental responsibility. It felt like Three Men and a Baby, only here it's Kong with a baby Kong."

The Skar King is suggested to have instigated the war between Godzilla and Kong's species/the Great Apes.

A leaked photograph from an early screen test revealed an initial design of Shimo, depicting Shimo's head with a terrapin-style appearance before the final design featured a different head.

Director Adam Wingard has said that certain elements of the monsters' battles were inspired by video games, even featuring nods to the Pipeworks Godzilla video-game trilogy.

Measuring 847 feet, Tiamat is the second-longest of the MonsterVerse Titans, exceeded only by Na Kika, which measures 898 feet.

Adam Wingard has explained that the scene of Kong's tooth replacement was included because, as he put it, the film served as a kind of catharsis. They were also trying to find memorable moments and opted for something universally recognisable — a trip to the dentist — but blown up to an absurd 300-foot-tall scale. It was actually one of the first ideas he knew he wanted to pursue in this film.

"Skar" is a Scots dialect word meaning "wild".

Although the Mini-Kong is younger than Kong in Kong: Skull Island (2017), it is still at least 45 feet taller than Kong was in that film.

Like the MUTOs that preceded him, the Skar King is an entirely original creation for the MonsterVerse.

Early promotional material for Godzilla x Kong: The New Empire suggests that the red handprints seen in Kong: Skull Island (2017) and Godzilla vs. Kong (2021) were those of Skar King's.

The image of French soldiers standing in a footprint left by Godzilla is a nod to TriStar’s Godzilla (1998) film, in which Matthew Broderick's character is seen standing in a footprint made by the eponymous monster.

This is the second entry in the MonsterVerse not to feature a human antagonist; the first was Godzilla (2014).

An image of a cave painting showing Shimo in Call of Duty surfaced as part of the promotional placeholder for the digital edition of the Monsterverse graphic novel Godzilla x Kong: The Hunted, suggesting the monster's presence in the film prior to any official announcement.

One Easter egg is the username used by the man who trolls Bernie: "GhidorahStan64." Ghidorah was the antagonist in Godzilla: King of the Monsters (2019), while the "64" quietly nods to the year the monster first appeared in Ghidorah: The Three-Headed Monster (1964). GhidorahStan64 is also the username of a Toho Kingdom administrator, whose account and services were offered to the production and accepted. Many fans spun elaborate theories suggesting the handle could actually be Ren Serizawa — or even Mechagodzilla's consciousness — now loose online.

Director Adam Wingard said he would be open to making a third film featuring both Godzilla and Kong, but added that "it just depends on how [Godzilla x Kong: The New Empire] performs and how things ultimately pan out".

Rebecca Hall described why returning for the sequel proved "even more enjoyable". "Honestly, there was a real feeling of ease when I came back," she said. "Being invited back to perform in a project like this is a tremendous vote of confidence for an actor. The role was enjoyable the first time, but even more so now because she has greater authority — which is refreshing for a female character, among other things, in one of these films. It's brilliant."

Kaylee Hottle explained the significance of humanity within the kaiju universe and how both the kaiju and humankind are seeking ways to coexist, "The monsters have their own world and we as humans are trying to understand that world, we're trying to find the path that links us. Then there's Jia — she's human too, so she can reach out to people in the human world while also connecting with her Hollow Earth tribe."

Adam Wingard has said that Godzilla will manifest in "a variety of forms" in the film.

Godzilla and Kong encountering one another amid the Great Pyramids of Giza was inspired by the fight in They Live (1988) by John Carpenter. Adam Wingard said: 'My inspirations also come from rather unexpected places. I mean, my favourite film is They Live.' He went on to explain that the entire Godzilla–Kong confrontation in Egypt draws from the big brawl between Rowdy Roddy Piper and Keith David, because he loves that the standout sequence in that film shows two protagonists squaring off against each other, rather than a hero fighting a villain. That fight in They Live was itself influenced by The Quiet Man (1952), which features an extended fight between John Wayne and Maureen O'Hara; The Quiet Man was released in 1952, just two years before the original Godzilla (1954).

The Drownviper that Kong battles in the lake is a nod to the original antagonist planned for Kong: Skull Island (2017), which was intended to be a gigantic, water-dwelling serpent before it was replaced by the Skullcrawlers.

The MonsterVerse franchise's fifth instalment.

The fictional monster film poster from Ford Brody's bedroom in Godzilla (2014) turns up again in Bernie's room.

Rebecca Hall says her character — an accomplished scientist and single mum — represents "a pretty cool transition from damsel in distress archetypes to more 'lady in control in a leadership position'" for the King Kong Canon. She explained that she plays a very serious part and treats everything with earnestness; when she isn't solemn she tends to respond with deadpan humour. Hall describes herself as the last person likely to giggle in any situation, which is especially hard when working with funny co‑stars like Dan Stevens and Brian Tyree Henry, who are good friends and frequently make her laugh until she cries. It was tough, she admitted, but she takes a kind of perverse pleasure in delivering serious lines to a tennis ball on a stick. She said it's an interesting challenge: she saves up the laughter and then lets rip when someone calls "cut", trying not to take herself too seriously even though the character does.

For Adam Wingard, one of the main reasons he returned to the MonsterVerse was to put into practice what he learned on his first venture into large-scale, effects-driven filmmaking. "There's no way to plan for the sheer complexity of a film like this. By the time I reached the end of 'Godzilla vs. Kong,' I felt I was only just hitting my stride. Not just with the visual effects themselves, but with the finer points of having the confidence to judge where a monster should be looking from the perspective of someone working at ground level, and all the details in between. I came into this film with a clearer understanding of how to use the tools and with a determination to really push the visual effects and the animation further."

The interval between this film’s domestic release on 29 March 2024 and the release of Godzilla Minus One (2023) in Japan on 3 November 2023 is the shortest gap between two Godzilla films in the franchise’s history — just 147 days. The previous record stood at 235 days, between the 29 April 1964 release of Mothra vs. Godzilla (1964) and Ghidorah: The Three-Headed Monster (1964), which opened on 20 December 1964. Ghidorah: The Three-Headed Monster (1964) was scheduled for that date because Toho needed a replacement for Akira Kurosawa's Red Beard (1965) in its theatrical release calendar after that film was delayed.

Adam Wingard points out that, as an ape Titan akin to Kong, Skar King is more humanlike in both intellect and outlook than the other Titans. Unlike Kong, however, Skar King personifies humanity's worst traits and is a power-hungry tyrant.

Director Hampton receives considerably more characterisation than merely being Dr Andrews' hapless boss in the novel. She's in Honolulu when Godzilla first appears to confront the male MUTO — inside a hotel the MUTO is poised to destroy until Godzilla pushes it aside. While she's fully aware of how it might sound, she believes Godzilla saw her and deliberately diverted it rather than smashing it through the building, leading her to conclude he's far more than a mindless animal.

Bernie mentions his podcast is sponsored by "Gargantua Insurance", a nod to War of the Gargantuans, a film about two colossal ape-like creatures that battle one another. Two of the podcast's episodes are titled "Planet X on the Horizon" and "Monster Island."

Of the 11 Titans that were listed on monitoring screens but not shown on-screen in Godzilla: King of the Monsters (2019), Tiamat is the first to appear in a subsequent MonsterVerse film.

Some viewers argued that the monsters occasionally appeared to lack weight and a proper sense of scale. This may have been intentional, as the filmmakers drew inspiration from video games and designed the effects to be video-game-like.

Early in production, Trapper was burdened with a monologue that set out his backstory; Adam Wingard recalls it was about him being stranded alone with hyenas in Africa. The scene delivered a great deal of information about the character in a relatively short space of time. But Wingard was keen to introduce Trapper alongside the Greenflow track "I Got'Cha" from 1977, the song taking its title from the lyrics. They played the tune on set and Stevens sang along. Wingard said that when they saw the edit it became clear: "you could have Dan deliver a two‑hour monologue about his past," he said, "and you won't understand his character any better than by having him sing 'I Got'Cha' for 15 seconds of the film, because that alone tells you everything you need to know about him."

Rebecca Hall welcomed the chance to collaborate with both Brian Tyree Henry and Dan Stevens, she said: "I didn't work with Brian on the first film, but I do on this one, and that was an absolute thrill for me because I adore him and I adore this work. Dan's a very old friend and I was delighted to work with him again as well. I've known him for around 20 years, so it felt like family. It felt playful and fun, and I think that comes across in what you see."

The film's novelisation places the events in 2027.

Adam Wingard made it plain he wanted audiences to have a proper blast this time. He said: "It's almost like this one is a spoof of the previous film. The last instalment was dead serious when you're flying in there. And it was fun to be like, 'What's it like when Bernie goes through it?' So we played it from his perspective. It's almost shot-for-shot similar to the last film, but it has a completely different feel."

The moment when Godzilla stirs and strides out of the Colosseum, smashing a painting that depicts a plump Godzilla tucking into a pizza, serves as the filmmakers' rejoinder to critics who argued the 2014 Godzilla was overweight and disproportionately large.

The first film in the Monsterverse to feature Kong that does not include any Skullcrawlers.

Adam Wingard, Rebecca Hall, Brian Tyree Henry, Dan Stevens and Fala Chen were each born in 1982.

This isn't the first time the iconic Christ the Redeemer statue has featured in a Godzilla work; it earlier appeared in volume 3 of Godzilla in Hell, where a flashback shows it being destroyed by SpaceGodzilla.

Adam Wingard spoke about the attention given to the Mini‑Kong, Suko, describing him as the "heart and soul" of the film and saying his introduction reveals a new facet of Kong. While comparisons have been drawn to Grogu — aka "Baby Yoda" — Wingard emphasised that Suko is a more layered character than the typical Ewok stereotype and is considerably more dangerous than Grogu. He noted that Suko, sometimes referred to as Baby Kong, really anchors the film. Creating him was very exciting, Wingard explained, because in many ways Suko reflects how Kong might once have been, which is why their adventure works so well — Kong sees a lot of himself in Suko. Wingard rejected the obvious reading of Suko as merely a cutesy, toy‑like creature, saying the character is more complex and not what he first appears to be; Suko was always intended to be the centrepiece of the film and was great fun to develop.

In an interview with Entertainment Weekly, Adam Wingard explained that what makes the Skar King intriguing is that, as apes, these beings are not merely reactive animals but possess greater intelligence. He described the Skar King as a significant threat because, unlike most giant monsters, he does not act purely on instinct; he behaves in a deliberately calculating and malevolent manner. He makes choices and is driven by his ego, very much a dictatorial figure. Wingard said it was fun to work with a character who is both a gigantic monster and a scheming presence. The Skar King also differs physically from Kong in ways that make their clash compelling. Where Kong is large and muscular, aiming to overpower any obstacle, the Skar King is lankier and more cunning. Wingard revealed that the idea was always that his agility gives him an advantage in a one-to-one fight, yet he also possesses the Titan equivalent of a weapon of mass destruction. That combination makes him a multifaceted villain: he commands an army, controls an even larger monster, and is, in short, the opposite of Kong.

It is suggested that Skar King was overwhelmed by the Whiplash Crystal's power and used it to subjugate Shimo; it is also reported that he harnessed the crystal to enslave other titans. One could infer that Godzilla may already have been aware of Shimo's existence and might even have confronted her on a previous occasion.

The film's merchandise range also unveiled Shimo's design — a reptilian kaiju reminiscent of Godzilla, sporting white scales, blue dorsal plates and horns, and possessing ice-based powers — and confirmed it to be the same mysterious Titan teased during the "Operation Monarch" event for Call of Duty: Warzone.

When Godzilla makes landfall in Spain, a shot showing an F/A-18 Hornet taking off from an aircraft carrier is repurposed from Godzilla: King of the Monsters (2019).

Fans of the MonsterVerse who appreciated the continuity established in earlier films such as Godzilla: King of the Monsters (2019) were disappointed that that lore was not pursued further and that titans like Scylla and Timat were given only brief cameos in short skirmishes with Godzilla. This, however, is not unprecedented, as lore elements can be omitted or retconned to suit the story. For example, on the audio commentary for Godzilla vs. Kong (2021), Adam Wingard and his team admitted they made little effort to explain the Hollow Earth energy, choosing instead to favour the narrative.

The first Godzilla film to feature an "x" in its original title since Godzilla: Tokyo S.O.S. (2003), and the first ever to feature an "x" in an English title. As with the Japanese title of Godzilla: Tokyo S.O.S. (2003), the "x" is silent.

Dr Andrews' refreshed hairstyle was written into the script to match Rebecca Hall's contemporaneous makeover. Hall has said she frequently changes her look and, when she was told another film was happening, she explained to director Adam Wingard that her hair was currently a short, blonde pixie and that she didn’t want to wear a wig. Wingard agreed to weave the style into the story, calling it a cool, action‑led choice — they even cropped the back shorter — and opted to make the haircut part of Dr Andrews' promotion, giving the character a boss‑like energy. Hall added that she enjoyed a practical upside to the short hair this time: hair and make‑up were very quick and simple in the early mornings.

Jared Krichevsky described Shimo's design process as "very challenging". Tasked with creating an "ice Godzilla", his earliest concepts were considered overly draconic. One variant was modelled on the Gamera kaiju Barugon. In the end, Krichevsky drew on Komodo dragons and polar bears for inspiration, with elements of chameleons incorporated into the design as well.

It is the first film to include on‑screen appearances by both Kong and Mothra. Mothra had previously appeared in Kong: Skull Island (2017) and Godzilla vs. Kong (2021), but was shown only in cave paintings. Kong and Mothra almost formed a crossover in the unreleased 1966 project Operation Robinson Crusoe: King Kong vs. Ebirah, which later became the Godzilla film Ebirah, Horror of the Deep (1966).

The cave paintings that depict Godzilla "The Monster that Ate a Star" are a reference to Godzilla vs. Kong: The Official Film Novelisation, which features a similar scene portraying the same story.

For Skar King's design concept, as he was conceived to be the polar opposite of Kong, he was given a lean frame to contrast with Kong's musculature and stockiness. Jared Krichevsky modelled him on orangutans, hairless apes and gibbons.

Many fans were abuzz with theories about why Godzilla's dorsal plates had turned pink. In an interview with Total Film, director Adam Wingard explained he wanted to experiment with fresh appearances for Godzilla, trying different elements and colours. He added, "I didn't want it to be random, it's part of the story." That remark sparked further fan conjecture over the meaning of the pink spine. Numerous viewers theorised that the pink tint signalled Godzilla's newly acquired ability to absorb gamma radiation — a notion later confirmed by the film itself. The story shows Godzilla deliberately attacking a nuclear power station to take on radiation, and then facing the serpentine Titan Tiamat in the Arctic, where he absorbs radiation from her lair and his dorsal plates change. The pink-hued Godzilla subsequently uses his atomic breath to undo the Ice Age previously caused by Shimo, bringing the climactic conflict to an end. The revelation of his pink spines not only answered fans' questions but also enriched the character's development within the MonsterVerse.

One piece of concept artwork depicted what seems to be the final confrontation taking place not in Rio de Janeiro but in Moscow. It is possible that this change was prompted by Russia's invasion of Ukraine.

Ironically, this is not the first time Dan Stevens has been involved in a kaiju film — he earlier appeared in Colossal (2016) opposite Anne Hathaway.

On 21 February 2024, fifty images from a test screening of the film were leaked onto social media, revealing numerous details of the plot. These were followed by claims that the entire film had been leaked online.

Rumoured to be chiefly responsible for Earth's first ice age, Shimo is linked to the event known as the Huronian glaciation, which occurred between roughly 2,400 and 2,100 million years ago, lasted about 300 million years and was the longest glaciation on record; consequently, this provides an estimate for the age of this Titan.

Adam Wingard felt he needed Dan Stevens to make his character Trapper immediately likeable, calling Stevens his "secret sauce" — his knack for making any part he plays seem trustworthy. Wingard explained, "Whether he's a villain or a hero, there's something in Dan Stevens's charisma that makes people, young and old alike, warm to him. And of all the actors I've worked with, he's the one most casual cinema-goers will recognise, I think because he's done such a wide range of work."

Adam Wingard explained how he pitched the Mini-Kong, Suko, to studio executives by likening him to Grogu — pointing out that, early on when Baby Yoda was still fairly new during production, as a shorthand while talking the studio through the project he would describe Suko as "like Baby Yoda, but the sort who might eat the skin off your face." He said Suko is a scrapper: adorable yet feisty, a survivor who has been through a great deal, and there's a lot going on beneath the surface of the little fellow.

Water bottles were distributed to members of the film's production crew, bearing the label 'Hollow Earth Advance Team', possibly a nod to the Humanitarian Environmental Analysis Team (H.E.A.T.) from Godzilla: The Series (1998).

When asked about the difficulties she faced while filming, Kaylee Hottle spoke candidly. "One of the hardest sequences for me was having to use simulated telekinesis to communicate with the Iwi tribe," Kaylee explained. In that crucial scene, getting the communication right was essential, and the use of telekinesis was the sole way to make the connection. She also mentioned the challenges of working with visual effects (VFX) and performing opposite characters who weren't physically on set. "It was a bit tricky working with a character that wasn't actually there," she confessed. Nevertheless, under the direction of Adam Wingard, Kaylee quickly found her feet and managed those difficulties with confidence.

When asked about Shimo's design, Adam Wingard said it was "one of the riskiest things you can do in a series like this — when you're creating new characters everyone will inevitably scrutinise the catalogue of characters that haven't yet been updated and ask, 'Well, why this one and not that one?'" He added that his personal philosophy when designing for the MonsterVerse is that what makes its creatures feel like MonsterVerse monsters is a certain simplicity of design, which he strives to maintain.

Since the leaked toy line and images from the film's screen tests featuring Shimo surfaced, many fans began sketching her in an effort to guess her canonical appearance. After Shimo was confirmed to be female, a large number of fans started pairing her with Godzilla, and such fan art became popular.

Adam Wingard emphasised the need to establish an adversarial dynamic between the mini-Kong, Suko, and Kong. "Their rapport is entertaining because they do not see eye to eye straight away," he explained. He compared their interactions to a buddy-cop partnership, where friction adds layers to their relationship. Wingard defended Kong's rough treatment of Suko by noting Suko's behaviour had endangered Kong's life.

According to the film's audiobook novelisation, Kong would have slain Skar King if it had not been for Shimo's intervention.

Director Adam Wingard emphasised that the film places the monsters at the heart of the narrative. He told Reuters, "For the first time ever, it's possible to make a film that lets the monsters tell their own story from their own point of view. I was genuinely thrilled to craft sequences that are visually led, and at times we go as long as eight minutes without a line of dialogue and you are simply there with the monsters."

Tiamat's design bears several resemblances to Titanosaurus — particularly a seahorse-like head — and to Manda, whose body is reminiscent of a legless Asian dragon.

At 162.45 metres tall, Shimo is currently the tallest monster to appear in a Monsterverse film, surpassing King Ghidorah in height by 3.65 metres. She is not the largest in the Monsterverse overall, however; she is exceeded by the 258-metre-long Tiamat and the 274-metre-long Na Kika.

The electric shock from Kong's B.E.A.S.T Glove is likely a reference to his 1962 counterpart's electrical powers.

Director Adam Wingard said that Bernie’s line "I'm turning into water" was informed by his own experiences with psychedelics. He explained that one of the few lines he personally put into the film was that phrase because he'd previously had that sensation while on psychedelics. "Oh my God," he added, saying he thinks he has actually said that before, and that a line like that can only come from genuine experience.

When an image of Shimo's leaked design surfaced, many fans voiced criticism of its appearance, likening it to a "moaning turtle" and provoking a deluge of memes.

One of the things Adam Wingard learnt from "Godzilla vs. Kong" was that there were simply too many characters, which not only forced difficult choices during the film's editing stage — a part played by Jessica Henwick was cut entirely and the screen time for Lance Reddick and Eiza González was significantly reduced — but also resulted in a structure that left little room to get to know any of the characters, including the monsters. "Because there was so much going on there's only the little moments where you really got to get super intimate with the monsters," Wingard said. In this instalment the cast has been pared back and parallel narrative strands have been set up that feed into one another rather than competing with each other.

When asked how Shimo came into being, director Adam Wingard said that his wish to see Kong and Godzilla face a threat so vast that they would have to join forces helped give rise to this original kaiju. He explained the starting point was that Skar King would be the anti-Kong and Shimo the anti-Godzilla for the film, because he wanted a danger of such scale that the two would need to unite to confront it. Wingard also noted that Shimo is, in a way, a weapon of mass destruction — not easily cast as good or bad, but rather a blank slate, which is what makes her an interesting monster.

At the start, Kong tears a wart-dog in two, its green blood soaking him completely and making him look like Gaira from the kaiju film War of the Gargantuas (1966).

There are a handful of occasions where the camera frames Kong and Suko, the mini-Kong, in much the same way as it frames Kratos and Atreus in God of War.

Rebecca Hall admitted she struggled to maintain a straight face while filming, adding: "When you try to imagine Godzilla and Kong, that’s tricky." She told PEOPLE magazine, "It’s difficult, because more often than not it’s a tennis ball on a stick. Actually, at one key moment when [Kaylee Hottle's character] Jia reaches across and touches Kong's hand, they literally had a foam hand with a pointed finger that they were holding up towards her. It was hard not to laugh at."

Having seen the trailer for Takashi Yamazaki's Godzilla Minus One (2023), Adam Wingard and visual-effects supervisor Alessandro Ongaro chose to honour that film by inserting a close-up of Godzilla's foot into the scene in which the creature rampages through Rome.

Brian Tyree Henry explained why his character "should've stayed his ass at home." "Bernie figured he would gain a deeper understanding of Hollow Earth and the Titans, and if you watch him throughout the film, he spends most of it regretting the decision to go down there. I think he says 'Oh, my God' at least 79 times in the first hour," Henry shared. He added, "What I really love, though, is the focus on family and home in this one. You see our characters forming their own little families among one another. Rebecca Hall and Kaylee Hottle play mother and daughter, with Kaylee trying to discover where she comes from. Bernie, who no longer has anyone waiting for him at home and is desperate for a connection, and even Kong... Kong is trying to work out who he is and where he belongs after being alone for so long. So, I think that's what makes this film interesting: the idea of home is that you must abandon the things you thought you knew to find what lies ahead."

Dan Stevens explained what he admired about his character, "What I adored about Trapper was his rather lovely worldview — he sees this planet as our home. It isn't confined to one particular spot behind a fence somewhere. It's universal. Wherever we go, even into Hollow Earth, it is our duty to look after it. Home can be anywhere, and with anyone."

Despite Suko's charm, Adam Wingard made certain the character manifested destructive tendencies to offset his endearing traits.

Adam Wingard had his eye on Dan Stevens for the role of Trapper, and it took a touch of persuasion. In an interview with Forbes, Stevens said he was first approached about the part and that Wingard was very keen to win him over. The actor acknowledged that Wingard and co-writer Simon Barrett "wrote Trapper with me in mind, hoping that I would be lured in. Honestly, it wasn't hard for them to lure me." Later in the film there is a sequence in which Trapper pilots a high-tech craft through a swarm of electrically charged, bat-like monsters, and Stevens, not being made of stone, found that irresistible. Stevens said that moment sealed the deal for him. He recalled: "[Wingard] described the scene where Trapper goes and commandeers the HEAV, which stands for Hollow Earth Aerial Vehicle, and flies it into a flock of creatures that are humming with dangerous electricity and become instrumental in the climax of the film. He basically narrated that scene to me, and it sounded very cool. Then I read the script and to introduce a character by having him drop 60 feet off a crane into Kong's mouth to help take a tooth out, I thought, 'That is a cool way to introduce a character.'"

Adam Wingard told Blavity's Shadow and Act that the film runs parallel storylines: a human narrative centred on Jia and Kong on his own odyssey. He said what's striking is that both undertake mirror-like expeditions and experience comparable thematic growth as they explore Hollow Earth. 'They both begin in the same place,' he added. 'Both are isolated. Both feel detached from the world around them, and the film follows their journeys, which occasionally intersect.' As Jia, Kaylee Hottle forges her own route both on-screen and off. She explains how the production shifted her sense of what constitutes a home. 'Generally, home is home,' Hottle remarked. 'It's the house I live in — that's my home. But playing Jia made me realise there are many interpretations of what home can be, and it means different things to different people. For Jia, home is being with her community, yet she faces a choice: remain with her tribe or go with her mum. She has to work out where her home truly is.' Hottle also spoke about the film's significance for the deaf community and how they might relate to her character. 'Representation of a deaf person on-screen matters enormously, because as a deaf actor others may see themselves in a film or in any pursuit,' she said. 'Showing a young person in a film is crucial too. Jia undergoes this whole journey — a kind of world tour, if you like — and she is uniquely able to do it. She stands for so much.'

Dan Stevens said that getting back together with director Adam Wingard felt as effortless as two friends meeting up. Commenting on their planned continuing collaboration, he likened their partnership to that of Rutger Hauer and filmmaker Paul Verhoeven, saying: "You could see them go, 'Oh, we're going to do a medieval epic now, or we're going to do a gripping domestic drama now. It was just a case of pointing a stick and saying, 'Let's make one of those.'"

Monarch Outpost 53, the facility where Tiamat was held, may be an allusion to the Warner Bros film The Beast from 20,000 Fathoms (1953).

Director Adam Wingard was intent on minimising the human presence in the film so the emphasis remained on the two towering beasts. Wingard told The Hollywood Reporter that in the development phase his guiding maxim was 'Simplicity is key.' He said that by keeping the cast smaller they could craft a more intimate story: 'We can still spend time with the human characters, and at the same time we can spend more time with the monsters and not short-change one or the other.'

Kong's habitat in the Hollow Earth closely resembles his home/nest in King Kong (2005).

Jia entirely supplanting the Shobijin is effectively a retcon of a plot thread from Godzilla: King of the Monsters. During Mothra's emergence from her cocoon, before she summons the recharged Godzilla and joins the final battle, twin doctors and Monarch scientists Ilene and Ling Chen are shown. As explained earlier in the film, the twins (both portrayed by Zhang Ziyi) are third-generation members of the Monarch organisation, and a brief scene shows Dr Chen closing her eyes and sensing Mothra's presence even from hundreds of miles away. It is suggested that they serve as the Monsterverse's Shobijin, despite not being tiny fairy-like beings only a few centimetres tall. Given that Mothra was killed in the clash with Ghidorah, it appeared their part might have concluded. However, with Mothra's return, it made sense that they would feature in Godzilla X Kong. Now that Jia fulfils the role of Mothra's translator, their earlier presence feels retconned into little more than a nod to Toho's original Shobijin.

During Godzilla's clash with Scylla, he charges and leaps at his adversary, striking down onto her feet first — a move that evokes his well-known "drop-kick" from Godzilla vs. Megalon (1973).

Lead creature designer Jared Krichevsky has said that Godzilla's new pink aura was inspired by Goku's iconic Kaio-Ken transformation from Dragon Ball. He noted that he didn't see Goku Rose until years later and that the change was intended as a temporary state; in the film Godzilla absorbs Tiamat's DNA. Krichevsky explained the new appearance comes at a cost: the vast energy required for the transformation would force Godzilla to burn off all his excess fat, a condition that should shift as he regains full control. Director Adam Wingard told IGN that the transformation drives much of the story and that the pink colour was a deliberate choice rather than a random shift. Krichevsky also said Godzilla's pink form will make him the most powerful creature on Earth, though he cautioned that this superlative may not apply within Hollow Earth. Dragon Ball creator Akira Toriyama appears as an extra in the crowd scene of The Return of Godzilla (1984) and can also be seen on that film's poster.

In the trailer, Bernie calls Suko a "mini-Kong". Director Adam Wingard, at IGN Fan Fest 2024, also suggested the nickname "Baby Kong", misquoting the line from the trailer.

While speaking with CB, Adam Wingard described his excitement about his creative approach and mentioned another notable film that relies on non-verbal storytelling: "So, given the opportunity, I knew I wanted to make a film that was largely told from the monsters' point of view. And yes, it was really exciting knowing we were going to stage sequences that are driven by visuals and non-verbal beats. I've always loved sequences like There Will Be Blood, such as that opening scene, where I don't think there's any dialogue for five to eight minutes. Things like that were a real inspiration to me because they're so engaging. And, to me, it's a given you're going to have a bunch of monster fights — those battle sequences will be great fun — but what truly excites me are the moments between the battles, when the monsters are in their downtime."

Bernie has a few Playmates toys from Godzilla vs. Kong (2021) in his flat, in particular a Kong figure and the Battle Roar Godzilla.

This marks the first film in the MonsterVerse franchise to be made without the involvement of screenwriter Max Borenstein.

Bernie's outfit features pins of Bigfoot and the Loch Ness Monster, together with a Velociraptor badge that appears to be taken from the cover art of the 2002 video game Turok: Evolution.

One of the licensed tracks featured in the film is Kiss's "I Was Made for Lovin' You". Godzilla has previously been linked with Kiss through adverts for the EOS Kiss Digital X camera that depicted the FinalGoji suit wearing Paul Stanley‑style star eye make‑up. During a 1970s tour of Japan the original members of Kiss were also photographed with the 1974/75 Godzilla suit, and those images are available online. Kiss's bassist Gene Simmons has said his Demon persona is a blend of Lon Chaney, a mythical Japanese boogeyman and Godzilla. Gene Simmons and his family also attended the world premiere of Godzilla X Kong in Hollywood.

Thanks to this film and Dune: Part Two (2024), Warner Bros. became the first studio to amass $1 billion at the worldwide box office in 2024. They reached the milestone in 15 weeks, a new record for the studio, eclipsing the prior 17-week mark from 2018, achieved with Ready Player One (2018) and Rampage (2018).

Weta VFX supervisor Kevin Smith said about the Whiplash, "We employ this whip as part of the language of the fight to give him additional strength. There’s a shot where he’s jumping over Kong, wrapping it round the neck and pivoting to get behind and pull. We worked out a way to achieve that with the stunt team in sections. You have to see that he’s a sneaky bastard, and you have to rely on his facial expressions and body posturing. He’s been there a long time and he’s gone a bit stair‑crazy, and it’s almost as if he’s been waiting for Kong."

Dan Stevens admitted that he and his character "Trapper" are very much alike, and he insisted this wasn't simply self-praise. Both Stevens and Trapper come across as cool, handsome, witty and charming. Although Stevens did create the role, he said he drew a lot from his own personality when shaping Trapper: "I wouldn't say it's entirely me, but there's something in Trapper that I enjoyed bringing out in a world like this. He's optimistic, fairly happy‑go‑lucky, unflappable, has seen it all and isn't easily fazed. That's always a welcome presence in an ensemble film like this. It was a privilege to step into a part that felt so natural and comfortable and to do that with such brilliant people."

Several scenes underline how similar Godzilla and Kong are: each is first seen dispatching a hostile creature and emerging smeared with green blood; each battles serpentine Titans that they ultimately defeat by dismembering; each is later depicted taking an extended rest while recuperating from post-battle wounds; each seeks shelter in a human-built structure (Kong at the Monarch outpost and Godzilla at the Colosseum in Rome); and both obtain a corresponding power-up during the film’s climax.

The film doesn't explore the origins of Scylla and Godzilla's clash. However, the tie-in comic 'Godzilla x Kong: The Hunted' clarifies that their confrontation was far from a routine squabble between the two Titans. Scylla deliberately fed on radiation, either to spawn additional Scylla creatures or to build enough strength to challenge Godzilla. Whatever her motive, Godzilla detected her actions and intervened to halt them. It's a compelling explanation that makes Godzilla's battle with his rival all the more fascinating, knowing Scylla had grown stronger because of her secret agenda.

The cast said working with a green screen could be challenging at times, and on one occasion they had to act opposite "just a guy with a pole and a foam finger". Brian Tyree Henry, Rebecca Hall and Dan Stevens described Kong's neck as the art of keeping one's neck at the right angle to gaze up at him.

This marks the first occasion a specific Titan (apart from Godzilla and Kong themselves) has appeared alive and not merely via stock footage in a second Monsterverse film, with Mothra and Scylla from Godzilla: King of the Monsters (2019) and Doug from Godzilla vs. Kong (2021) returning.

All of the newly introduced major Titans in this film have names beginning with the letter 'S'.

Rebecca Hall joked that she didn't entirely grasp what Dr Andrews was doing with Monarch in the new instalment, and she also said she valued being able to tap into a very different kind of energy as an actress in this film. She explained: "it was fun this time around because the first time Dr. Ilene Andrews was a kind of a peripheral player at Monarch, and an important one, and I feel like in the time that has elapsed between the first film and this one, she's definitely had a substantial promotion. I don't even know how you would completely describe what she does." She added that she was simply pleased to have far more to play with in her role in the new film: "it's almost as if she runs PR for the Titans. She's looking after everyone. She's making tough decisions and she's also caring for a teenage child. So there's a lot to work with as an actor, and it was fun to come in with a slightly more, I suppose, 'boss energy' — that's the phrase I'm after... BBE, Big Boss Energy."

Concept artwork portrays Kong still wielding his axe and lacking the glove during the fight in Egypt, suggesting he did not originally lose it to Skar King.

Shimo represents the second confirmed female monster to assume the role of principal antagonist in a Monsterverse film, following the female MUTO in Godzilla (2014) (the gender of the Skull Devil in Kong: Skull Island (2017) remains unspecified).

When describing the father–son relationship between Kong and Suko, Adam Wingard likened it more to the dynamic of Homer and Bart from The Simpsons than to a conventional paternal bond.

Adam Wingard expressed a significant concern about introducing the Mini-Kong called Suko, warning that audiences might interpret the character as a deliberate manoeuvre to sell merchandise. He drew a parallel with the Ewoks, who are often singled out as examples of cute characters in mainstream media. Moreover, during the development phase of "Godzilla x Kong," Wingard noted the massive success of The Mandalorian, particularly the arrival of Baby Yoda. While he appreciated Baby Yoda’s appeal, Wingard wanted Suko to possess a similar charm yet remain threatening — envisaging a creature with Baby Yoda–like endearing qualities combined with a brutal side capable of biting and consuming flesh.

Brian Tyree Henry offered his take on what's really happening with the gargantuan monsters. He quipped that this instalment of the MonsterVerse is the most alluring yet, saying the film had to turn up the "sex meter" to address the "sexual tension" between the titular characters. He and his co‑stars went on to joke that this might be why there's an "x" in the film's title. "So, what you're saying is that this one is particularly sexy," Henry said. "We thought that's what this one needed, to fill that sexual tension between Kong and Godzilla. Is there something? Is there like... Yeah, Godzilla x Kong?" Co‑star Dan Stevens added, "Triple X," while the interviewer replied, "We're all shipping them now."

Director Adam Wingard revealed that the idea of a Mini-Kong, named Suko, first arose during a story meeting with producer Mary Parent when they were outlining the future of the Monsterverse. Parent suggested a 'Son of Kong' film, an idea that immediately captured Wingard's imagination. He continued to mull the concept over for the next two years. While developing "The New Empire," Wingard explored how a juvenile Kong could be credibly woven into the mythology, particularly intrigued by the prospect of Kong meeting others of his kind in Hollow Earth.

Shimo is the first Titan antagonist in the MonsterVerse to function as the secondary antagonist of a film. She is also only the second Titan to serve as an enforcer for a primary villain in the series — the first being Rodan, who served King Ghidorah. Coincidentally, both are elementally cloaked Titans capable of producing those elements at will: Rodan generates lava, while Shimo produces ice.

This film constitutes the second occasion on which Godzilla is depicted feeding on radiation from a nuclear power station, the first being The Return of Godzilla (1984).

When asked about the sequences that's solely concerned with the eponymous monsters interacting amongst themselves and with others, Adam Wingard explained that he's been mulling the idea for some time and that it represents a long-held conviction: "This all stems from my experience making Godzilla vs. Kong, having endured the years required to produce a large, special-effects-driven monster film. I truly came away from that with the confidence of knowing, like, 'You know what? The special effects are there, the technology is there and the confidence is there.' And when it came to making this film, that was the direction I wanted to take. I wanted to transport audiences to a place I've always wanted to see. When I was a child growing up in Alabama, in pre-school, watching the Godzilla films, my biggest fantasy was that these films could endure far longer with these monsters, and I felt that many filmmakers had recognised that."

The film's visual effects were handled by four companies: Weta FX, Scanline VFX, DNEG and Luma Pictures.

For Skar King’s creation, Adam Wingard enlisted Weta FX to animate the antagonist. They redesigned the concept to ensure his biomechanics aligned with the intended movement and made him look more battle‑scarred, even adding a cat’s‑eye reflection in one eye.

Kong's clash with Skar King highlighted a study in contrasts: Kong is the taller, more powerful gorilla, built for head‑on, brute‑force assaults with his axe, while the orangutan is leaner and more furtive, preferring attacks from behind with his signature Whipslash — a sharp bone weapon strapped to his torso that can slash and strangle enemies and contains the crystal that controls Shimo. Weta animation supervisor Ludovic Chailloleau said: "He has very long arms, which dictated the way he would move. He gives you a slight tilt of the head and you do not notice, yet his arm is already on your leg; that is how we came up with this sneaky attitude, something we crafted for him. So when he emerges from his cave he uses his arms, planting them as a spider monkey would. He is very agile."

According to VFX supervisor Kevin Smith, the notion that Kong should use the Mini‑Kong Suko as a weapon came from Alessandro Ongaro. Smith recalled that everyone instantly loved the idea — it felt like 'that's an incredible idea' — and the animation team developed it further; they were all hoping the studio would accept it, as none of them expected it to remain in the finished film. Additional visual‑effects supervisor Nick Epstein said that when he viewed the previs the team were stunned and found it uproariously funny, calling it one of the greatest moments he'd ever seen and saying he truly hoped it would make the final cut, which is why he was determined to make that sequence work. Animation supervisor Ludovic Chailloleau described the beat as pivotal to Kong and Suko's relationship: it is the first time Kong encounters another titan, and the film hinges on Kong's solitude until this meeting. The small measure of trust Kong extends proves misguided because Suko betrays him, so it becomes a gratifying moment when Kong takes revenge and uses Suko as a weapon.

According to animator Lee Sullivan, they were explicitly instructed not to tamper with the Colosseum in which Godzilla sleeps. They were forbidden from demolishing any of the existing fabric, though they were permitted to construct additional elements that could be destroyed. They simply weren't allowed to destroy anything that was the 'original' Colosseum.

According to Adam Wingard, Shimo is regarded as one of the most immature Titans; he adds: "her personality isn't fully formed, so Skar King is somewhat exploiting her." It is also implied that she and Godzilla clashed previously, which helps explain why he evolved to become warmer in demeanour.

At 53 minutes into the film the submarine's captain says that "too much energy is damaging our radar". Whilst submerged, a submarine is more likely to be using "sonar" than "radar".

A diorama depicting Egypt sits in Jia's classroom, featuring a toy monkey perched atop a pyramid — a subtle hint at Kong's later arrival in Cairo.

The novelisation features a number of additional creatures, including the Diraffe — a cross between a giraffe and an armadillo with an otter-like head — beetles that feed on electricity, and enormous river leeches.

The novelisation opens in 2016 with a prologue in which Ishiro Serizawa, Vivienne Graham, Ilene Andrews and Emma Russell visit Ghidorah's resting place and establish the existence of a "quintessential Titan" that precipitated the last ice age. It also reveals that Godzilla waged war against the Skar King, fighting alongside other Titans loyal to him.

Weta FX made Kong look older by modifying his fur grooming and reconstructing his internal skeleton to align with the technology they developed for Avatar: The Way of Water (2022). They also animated Suko with grubby, unkempt fur grooming to emphasise his punk‑kid persona.

On the Playmates toy, the Wart Dog sports a markedly different design. A distinctive trait is its head, which bears a strong resemblance to the Skullcrawlers'.

After directing the previous film, Adam Wingard aimed to broaden the MonsterVerse with some personal touches. One of the most obvious changes was Kong’s updated appearance. Weta VFX supervisor Kevin Smith remarked "For Kong, they wanted him to look a little older, a little greyer, to show the passage of time. One thing I noticed in the artwork was that his beard was longer. The funny thing is I hadn’t seen Adam in ages, and when we first got on a call he had a huge beard, so we knew where that came from." As before, the team used motion capture for performance reference and then keyframe-animated the characters, but advances developed for the Avatar sequel delivered better results. Weta animation supervisor Ludovic Chailloleau said "We relied on the underlying muscle technology. When you want Kong to convey an expression, you get much better and faster results. So going from a smile to a frown is more realistic because those facial shapes blend together more effectively."

In the novelisation, the Skar King's motivations are further developed: besides seeking to claim the surface world, he also intends to invade it and exterminate all life there to further assert his dominance. One reason he enslaved Shimo is to advance this aim by controlling a titan extraordinarily powerful by their standards — potent enough to trigger an extinction-level catastrophe.

One of only two films from 2024 to prominently feature KISS's single "I Was Made For Lovin' You". The other was The Fall Guy (2024), which premiered in the same month as this film.

Director Adam Wingard has confirmed that Godzilla acted out of selfish, self-serving motives and that Tiamat was an innocent being who was driven out and killed for the sake of the planet. He added: "He will protect the Earth by any means necessary."

The contrast between Kong and Skar King's behaviour shaped how their confrontations were staged. Weta VFX gave asymmetry to Skar King's eyes and mouth, and he moves with a calm confidence born of thinking several steps ahead of Kong. He secures the opening victory in his lava-swept lair by capitalising on surprise. Skar King employs his Whipslash to disarm Kong; Kong then manages to overpower him until Skar King unleashes Shimo.

The Wart Dogs bear a likeness to palaeontological reconstructions of the prehistoric mammal Andrewsarchus.

Speaking to Discussing Film, Adam Wingard named the Toho picture he would most like to mirror within the Hollywood MonsterVerse as Godzilla vs. Destoroyah. Wingard commended the film for its 'emotional highs', saying the finale moved him to tears, and singled out the scene in which Godzilla Jr. and Godzilla die as particularly powerful. The director of Godzilla X Kong added that if he were to return to the MonsterVerse he would aim to achieve that same emotional resonance for Godzilla as a character. He explained that Godzilla vs. Destoroyah ranks among his favourite Godzilla films because, aside from Minus One and the 1954 original, he felt few other entries reach those emotional peaks. In his view, the ending — when Godzilla Jr. dies and Godzilla subsequently melts to death — is both poignant and beautifully handled; the first time he watched it it 'brought tears to [his] eyes', a reaction he partly attributes to Akira Ifukube's sweeping score. Wingard also observed that Destoroyah represents a very refined example of an actor in a Godzilla suit — perhaps the high point of that approach in terms of scale and quality — and reiterated that capturing that level of feeling would be his goal in a future film.

For the scene in which Kong meets the Mini‑Kong, Suko, additional visual effects supervisor Nick Epstein revealed "it's set inside an enormous cave full of clouds — very mysterious, and the environment is vast. We had to come up with a procedural dressing solution that would work no matter where the cameras were placed. Ultimately we produced astronomical amounts of geometry. At one point our in‑house renderer had some arbitrary limits that needed raising because we simply had so many instances; no one had ever tried to push that many through before. It was something like 400 million instances in that ape fight. We also built a procedural ground‑interaction system that would decide what needed to be activated. All of those elements would then be carved off into the FX package, simulated, brought back into the lighting scene and removed from the main layout so you didn't have to worry about them. It was all nicely automated by Murali Ramachari, my FX supervisor. Alessandro Ongaro carried out a recce/reference shoot in Iceland, filming lots of plates from a helicopter that proved really useful here. We used them for texture projections, and because they were shot from the air they matched our scale. They gave us a real‑world breakup without looking too procedural or repetitive and remained at the right scale. Then the comp team did a great job of handling all of that. We always wanted the frame to feel as if something was moving, even if it was only a very slow drift of atmosphere."

In the film's novelisation, red-painted apes loyal to Skar King are referred to as 'Red Stripes'.

For the sequence where Suko, the Mini-Kong, tries to get Kong killed at the lake, visual effect sequence supervisor Stephen Tong revealed, "that environment is quite huge. You're inside the forest and then through the forest you come to a vast lake, and behind that there are all those mountains and a ceiling at the rear. This time around we wanted to create environments with more colourful mountains, where you can see mineral oxidation across the slopes. On top of that, we ran full water simulations with the enormous creatures. One conscious artistic choice we made for the giant creatures was to have them move a little faster than you would expect from a 100-metre-tall being, which makes their fights more exciting to watch. That, however, brings challenges for the physical simulations — the water and the interactions with trees are particularly difficult to dial in."

According to VFX supervisor Kevin Smith, Skar King was initially imagined as nearly bald; they already had a Mudbox sculpt when the art was handed over. He described the creature as very orangutan-like. Because the design was long and skinny, the team wanted him to be the opposite of Kong: Kong was conceived as a Mike Tyson-type — compact and powerful — whereas Skar King was intended to be more furtive and graceful. They first tried a slightly bald look, but it tended to make him read as an elderly figure. The other major task was to rework the design biomechanically: with such long arms, conventional animation alone wouldn’t produce convincing movement, so the crew altered joint placements and adjusted proportions so he could fight and move believably. Animation supervisor Ludovic Chailloleau said he had an immediate, positive reaction to the long-armed design, since it made Skar King essentially the inverse of Kong. Kong is very square and all about strength — solving problems by smashing and breaking through — while Skar King is a sneaky manipulator. The team approached his motion with slack, furtive gestures; he moves asymmetrically rather than head-on like Kong. His long arms became part of his body language, giving him an enormous reach and allowing him to swing in a spider-monkey fashion, which produces a strange sense of speed because he doesn’t need to shift his whole body much. They used motion capture, performing his actions on stage with arm extensions and prosthetics so performers could reach far enough to plant the tips of the arms and propel the entire body quickly toward the camera, then let the arms fall to the ground in a very relaxed, slovenly manner — almost like a gangster.

The film’s Japanese dub features a number of voice actors who have previously contributed to other Godzilla or King Kong projects. Maaya Sakamoto and Matsuya Onoe return to their roles as Ilene Andrews and Bernie Hayes, respectively, from the dub of Godzilla vs. Kong. Mamoru Miyano voiced Haruo Sakaki across all three instalments of the GODZILLA anime trilogy. Miou Tanaka played Captain Hotta in Godzilla Minus One. Rie Takahashi, Fumihiko Tachiki, Jun Fukuyama and Maaya Uchida provide the voices of Chibi Mothra, Chibi Hedorah, Chibi Godzilla and Chibi Minilla respectively in Chibi Godzilla Raids Again. Akio Otsuka voiced Jack Prescott in the Nippon TV Japanese dub of King Kong (1976) and was part of the cast for the TV Asahi Japanese dub of its 1986 sequel, King Kong Lives. Shinsuke Kasai made cameo appearances in four of the six Millennium-era Godzilla films, has hosted several Godzilla-related events, appeared in all the Godzilla Fest short films, and lent his voice to both a radio announcer and a man caught in an explosion in Godzilla Minus One. He also provided the voice of Guillermin in the Japanese dub of the previous Monsterverse film, Godzilla vs. Kong.

At 47:31, when a character exclaims "Great Mulder and Scully, look at that", he is invoking the names of the two principal characters from The X-Files.

The Wart-Dogs were conceived by art director Nick Lloyd, who drew on hyenas with cataracts, eagle talons, the diseased hides of water buffalo and ailing wild dogs for the creatures' eyes, claws, skins and scars, respectively. Animation supervisors Eric Petey and Bill Bridges initially studied wolves, African painted dogs and hyenas to inform the creatures' running style, but—owing to the Wart-Dogs' heavy collars and pronounced shoulders—also introduced the more powerful bounds of big cats. Hyenas proved useful again when animating the Wart-Dogs to be twitchy and unpredictable. One of the most challenging moments occurred when Kong tore one in half, which required the model's muscle system and layers of fat to be developed to include internal organs.

The toy line for Godzilla vs. Kong featured two "Titan Tech" figures, one for Kong and one for Godzilla, each capable of converting into armoured/cyborg versions. The styling and the packaging blurb suggest Monarch devised them to enhance the Titans so they could face larger threats. In the film, Kong is given a powered armoured glove that shares several details with his "Titan Tech" figure's flip-out armour, and the glove is described as having originated from the cancelled Project Powerhouse, intended as a strength-enhancing exoskeleton for Kong.

Adam Wingard was also keen to bring back the fan-favourite Mothra, who previously appeared in Godzilla: King of the Monsters (2019) but was killed by that film's end. Wingard recalled that when King of the Monsters was released his dad went to see the film and immediately said how much he loved Mothra — a remark that stuck with him. He noted that while other Titans are often shown battering one another, Mothra functions as a more ethereal presence, which the new film needed. Ultimately, Wingard found a narrative way to reintroduce Mothra's species into the MonsterVerse while broadening the franchise's lore. As he explained, "This is essentially Mortha's mother... The eggs that were laid on the surface were laid by [The New Empire's version of Mothra] and this establishes that she is the protector of the pathways to the surface, which are these vortexes. And so, theoretically, this Titan has access to these vortexes and laid eggs on the surface, which is what we saw in King of the Monsters. She is the OG one."

Greg Hatton, who portrays Lewis — the seismologist at Monarch Outpost 1 — was based in Hollow Earth. His LaBrea character, Virgil, likewise fell into the Earth through a sinkhole and became trapped in 10,000 BC. Both productions were shot concurrently.

Incidentally, Toho's Godzilla Minus One was pulled from US cinemas eight weeks before the release of Godzilla x Kong: The New Empire.

According to additional visual effects supervisor Nick Epstein, the ape Kong helps to his feet after being kicked by one of the guard apes was nicknamed "Boots". Epstein remarked, "we were experimenting with making him seem a little more sympathetic. We didn't want them to come across as just these great big brutes. So there was definitely a design phase and thought given to what people would connect with. We may have dialled in a little of Suko to some of those apes as well."

According to visual effects supervisor Kevin Smith, one of the most challenging elements was the Skar King's weapon. He said, "the moment we saw that skeletal spine weapon, we were like, 'Oh, man.' It was incredibly difficult to get it to behave the way you wanted by any kind of programmatic or automated means without having to constantly tweak it by hand. Fortunately, it either sits curled around him so we can hide the parts we don't want the audience to see, or it appears in fights where its chaotic motion is enough that you don't really notice imperfections. I think it comprised 108 or 110 vertebrae, plus the jaw handle and the piece at the end. It was hard. Ninety-nine per cent of people will see this film and not realise that was one of the toughest things we had to do — not to mention providing Ludo and the animators with controls for when you want to drive the motion in an animated way."

For Shimo's design, additional visual effects supervisor Nick Epstein explained, "Shimo contained an enormous amount of geometry. We did not want to treat all of that purely as displacements, so she ended up being quite heavy. The appearance of the crystals and their refractive properties were particularly costly to render. She is very luminous and white as well. She was rather distinctive because she is even larger than Godzilla and larger than Kong — a proper titan. Keeping a convincing sense of scale for her was another difficulty, especially given she had to be prepared and handed off to other suppliers. She was truly beautiful, and we had to strike a delicate balance between making her elegant and simultaneously threatening." Animation supervisor Ludovic Chailloleau said, "One of the challenges when we began work on that large sequence — the fight between Kong and Skar King — was establishing the nature of the relationship between Shimo and Skar King. Shimo was animated predominantly with keyframes, because you cannot realistically motion-capture a dragon. Whereas Godzilla moves more like a lizard or even a dog, Shimo is not dog-like; she moves more like a cat. Her motion is feline, and that was crucial in determining her behaviour — less brutally forceful than Godzilla."

Director Adam Wingard has explained that the Mini-Kong Suko’s chest-thumping is intended to mirror his watching of Kong, whom he now regards as a father figure.

The animators had to construct the entire sequence in which Skar King begins to exert control over Shimo using the whip and the crystal.

According to additional visual effects supervisor Nick Epstein, Shimo's ice beam proved to be a rather intricate operation, featuring subtle frozen vapour in the air and ice shards that reflected the beam — in total, some thirty-plus FX layers were used.

Unlike Kong or the mini Kong Suko, Skar King doesn't beat his chest. This is accurate, because in real life, unlike gorillas, chest-beating is not a typical behaviour of orangutans.

The film's release in Japan, scheduled for 26 April, falls on the birthday of Godzilla's creator, Tomoyuki Tanaka.

The Drownviper is the fifth serpentine creature to have battled King Kong on film, following the Elasmosaurus, the Giant Sea Serpent, the Giant Boa and the Warbats.

Legendary Pictures formally pressed ahead with a sixth instalment in the Monsterverse on 10 May 2024, appointing David Callaham to write the screenplay. The Hollywood Reporter reported that, although the studio is keen to retain Wingard as director, he has not yet signed a contract and has committed to shooting a film for A24 in the autumn.

Adam Wingard has said that Shimo possesses enough power to destroy the planet.

According to Adam Wingard, Skar King's fur isn't naturally red — he paints it himself. He uses war paint to denote rank: those of higher status bear facial paint, whereas the worker class do not. When they pledge their allegiance, he scars them physically, hence the name.

Shimo originated from Adam Wingard's desire to push the limits of visual effects, aiming to craft a creature whose skin carried a pearlescent sheen. "I didn't want her to be just another monster with a leathery hide. Depending on where the light struck it, I wanted it to have that shimmer like petrol does," Wingard said.

A photograph of Adam Wingard's cat, Mischief, can also be seen in Monarch Outpost One.

Godzilla and Kong each confront serpentine adversaries — Tiamat and the Drownviper, respectively — and defeat them by severing them into pieces.

The Skar King's "mutton-chop" facial fur was modelled on that of Warbat designer Matt Millard.

Early in the film, whilst recording his podcast, Brian Tyree Henry's character (Bernie Hayes) refers to Gargantua insurance — a neat homage to Ishiro Honda's 1966 cult classic, The War of the Gargantuas.

The Asylum, an American studio known for producing knock-offs of major blockbusters, made Ape x Mecha Ape: New World Order to capitalise on Godzilla x Kong: The New Empire. It was released on 5 April 2024, one week after Godzilla x Kong: The New Empire opened in US theatres.

According to Scanline VFX supervisor Nick Crew, realising the B.E.A.S.T. Glove "posed several major challenges, mostly connected to technical functionality and the character's performance. Securing such a large metal-plate structure to something that moves so independently and multi-directionally as a hand and forearm introduced multiple rigging and asset-design problems that had to be identified and addressed. To help devise solutions, we once more turned to our art director and concept artist Nick Lloyd to carry out initial sculpting and articulation explorations, which helped us arrive at a first workable design." The Scanline team sought to demonstrate the glove enhancing Kong's strength by designing "additional interlocking mechanisms" for when he went on the attack and by adding electrical and steam effects.

Mothra's name is never spoken on-screen because her inclusion wasn't confirmed until late in production. Accordingly, the film was shot with no cast member saying 'Mothra'; every instance of the name was added later in post-production using ADR. Characters only mention Mothra in shots where their mouths cannot be seen.

Alex Ferns (Mikael) appeared in The Legend of Tarzan (2016) alongside Alexander Skarsgard, who portrayed Nathan Lind in Godzilla vs. Kong (2021).

The motion-capture actors portraying the Skar King wore arm prostheses to replicate his reach and achieve authentic movement.

The Hollow Earth battle was one of the earliest ideas proposed and offered an opportunity for Godzilla to display some of the Showa era's more outlandish antics.

Although Shimo moves solely on all fours in a bear-like stance, some merchandise depicts her standing upright on two legs.

Visual effects supervisor Kevin Smith revealed that Shimo ranked among his favourite aspects to work on in the film; he said, "I was rather worried for a while because there were so many spinning plates and so much of it was actually very difficult to get right. The skin in particular, the scales set in the crystals along her back, and the icy breath — all those things were technically and artistically challenging. I'm not the 'toy guy'; if you saw my office, it isn't full of maquettes, but I might actually get a Shimo because I'm quite proud of how she turned out. She's a cool character."

Godzilla teams up with Kong and the Mini-Kong Suko to battle the Skar King, Shimo, and an army of apes within Hollow Earth. Supernatural forces cause two pyramids to collide, producing a zero-gravity scenario. The sequence was filmed using motion-capture with performers suspended on wires. Weta VFX supervisor Kevin Smith said: "We brought every performer onto our zero-gravity stage and devised a shot-by-shot plan." The choreography encompassed floating, rotating, collisions, pauses, follow-throughs and re-strikes. Weta animation supervisor Ludovic Chailloleau added: "You have these two enormous figures. One wields a whip much like Indiana Jones's, able to snatch things from a distance and draw them in. The other carries an axe but loses it. Floating boulders are everywhere, so combatants can spring from the rocks, hurl them or use them to shove. There is also a transition as gravity returns, where they move from floating back into freefall." The action remains unresolved as it spills out to Rio de Janeiro (a sequence Weta didn't handle), where Shimo freezes the city and Godzilla and Kong must join forces to stop the Skar King and Shimo pairing. Smith added: "It was almost a way to fill time until we could move them from Hollow Earth to Rio, where the confrontation concludes. In that respect it allowed us to prioritise spectacle. Adam let us experiment after trusting our beats from the previous film. You can ease off the exposition and crank up Godzilla — who emerges from underwater and is the only one who seems composed once zero-G sets in — or have Suko hurling rocks at an ape and knocking One-Eye off. The trick was balancing Newtonian physics with keeping things entertaining."

In the Japanese-language dub, the character Trapper is voiced by Mamoru Miyano, who earlier voiced protagonist Haruo Sakaki in Gen Urobuchi's Godzilla animated film trilogy.

The voyage across Monarch's Islands, the "Vile Vortex" and Hollow Earth's "Veil" showcased the skills of DNEG'S team in simulating intricate visual phenomena — from cloth dynamics to the interplay of reflected light — which added a deeper sense of authenticity to the film's fantastical elements. DFX supervisor Eric Chan commented: "Our team built a visually striking world characterised by upside-down glowing pyramids and gigantic creatures. The project demanded pioneering new lighting methods and advanced CG environment workflows. Close collaboration with the concept team was essential to integrate the visual effects smoothly and support the story. One of the most notable challenges was the vortex — a portal that allows Kong to travel between realms within Hollow Earth — realised through sophisticated FX simulations. This endeavour not only pushed our technical limits but also broadened our creative horizons, marking it as a pivotal experience in my career."

Adam Wingard said he is thrilled by the film’s reception and is eager for more, explaining that there’s always a temptation to expand it into a trilogy and that there are still unexplored avenues to pursue. He also pointed out that there are ways to keep innovating the MonsterVerse’s stylised approach, and that a real strength of the MonsterVerse is how it has allowed many different directors to bring their own distinctive style and colour palette to it.

"Iwi" in Māori simply means "tribe", so they are effectively saying "The Tribe Tribe". Moreover, Rachel House would be aware of that. Her Māori iwi (tribal) affiliations are Ngati Mutunga, Te Atiawa and Ngai Tahu.

Early concept art indicates Godzilla's evolved form was originally intended to feature bone‑white dorsal plates, modelled on those of Godzilla Ultima from Godzilla: Singular Point (2021).

Despite the vast scale of the titular monsters, painstaking attention to detail was crucial for the closer, more intimate scenes between Godzilla and Kong. For instance, the close-up of Kong's facial reactions during the tooth-extraction sequence required highly detailed skin textures and very subtle facial movement. Senior visual effects supervisor Paul Franklin said one of the shots that really challenged the team was an extreme close-up of just Kong's eyes and his nose — the rest of his face isn't visible because he is asleep. He had been anaesthetised and Trapper was about to land on him. The amount of skin detail that needed to be revealed there was enormous, and the team worked hard to eke out every last pixel from the textures applied.

Alessandro Ongaro, the visual effects supervisor, says the zero-gravity battle was "probably one of the most complex" scenes to create, and Wingard adds, "It's such a challenge to find new ways for monsters to fight that you haven't seen before. The zero gravity gave us licence to really bring out a grounded version of the absurdity of the Showa films where Godzilla can fly through the air and dropkick and stuff." However, some fans were disappointed that the filmmakers did not go the whole way and did not actually have Godzilla perform the infamous dropkick from Godzilla vs. Megalon.

To suit the Skar King's personality, concept artist Jared Krichevsky shaped his face to give the ape an unpredictable, psychopathic appearance, thereby setting him apart from Kong's more benevolent demeanour.

The production features more than 310 visual effects shots, distributed across 20 sequences.

For Godzilla’s gait, animation director Spencer Cook revealed: "We actually attached a speedometer to his feet to see how fast they move. When a foot is lifted off the ground and swinging forward it can reach up to 200 miles an hour. But at that scale it simply reads as a slow, heavy plod. That’s another example of the range of speeds that gives it a natural feel as well as a sense of mass. Godzilla taking a step, for instance, as it leaves the ground and begins to move forward is deliberate and slow. Then as the foot comes down it accelerates, and that’s where you get the big, heavy impact. The slow lift and forward motion is what provides speed variation and lets you maintain the impression of weight, alongside the hard stomp."

The Whipslash accessories included with the Giant and 6" Skar King figures from Playmates do not include the crystal seen on the final design; they instead feature a handle where the crystal would be. The figures' accessories are also made to be gripped by that handle rather than by the Warbat's jaw as depicted in the film.

On his early concept passes, concept designer Jared Krichevsky presented Skar King with markedly different hairstyles and varying amounts of fur.

A HEAV control panel is briefly glimpsed showing two biomimicry settings alongside the Vertacines. They appear to read "Graphosoma" and "Aspidimorpha", both insect genera.

According to additional visual effects supervisor Nick Epstein, "initially we planned for 100 apes in Skar King's lair, but in the wide shots we ended up with roughly 130. We built them modularly. We needed the same facial rig to be transferable to all of them even though their faces differed. They were all based on the same base mesh. We produced shading variants for the different paint patterns, used different grooms, varied their scale and their colours. We implemented a fairly loose hierarchical system: if an ape had one stripe, it would be placed at the first tier in Skar King's eyes, and the more stripes it had, the closer it would be to Skar King's lair."

This film pushed the MonsterVerse franchise past the US$2 billion mark at the worldwide box office.

For the fight between Kong and Skar King, visual effects supervisor Kevin Smith revealed: "The sequence ended up being roughly twice as long as it was when the clients first handed it over because they kept adding additional story beats, which was great as it allowed us to be involved in helping tell that story. Elements like the ape that gets kicked into the lava, which leaves Suko so upset, were added later. Some of the actions Skar King performs before the actual fight were intended to establish who these apes are as characters. We previsualised this ourselves to flesh that sequence out." Animation supervisor Ludovic Chailloleau said: "In that fight they're swinging around a lot, so there was a huge amount of motion that we wouldn't really capture. There's always a lot of keyframing after the capture anyway because these are heavy characters doing wild stunts that we can't really reproduce on stage."

In a special feature on the home media release, director Adam Wingard discussed the dialogue-free moments with Kong as he goes about his business, explaining: "One of the very first conversations I had with the writers on this film was that I wanted to make a mainstream blockbuster that didn't rely on dialogue. I wanted to make a non‑verbal film." Rebecca Hall added: "It's more like a silent picture. We're going to see Kong form relationships, show anger, crack a joke, be emotional and be moved. We've seen that before but I think this is more nuanced." Wingard summarised everything by saying: "Audiences are ready for a more immersive trip into the monster world. I can really stretch my imagination and let these monsters tell their own story and take it to the next level. Kong can simply be our hero; he can guide us through."

Although "VERTICINE" appears in the redacted text during the opening credits of Godzilla x Kong: The New Empire (2024), the majority of sources use the spelling "Vertacine". That form is found in the film's novelisation, the Japanese theatre programme, AMC Theatres' closed captioning, the "Monsters of Hollow Earth" home‑video featurette and the mobile game Lords Mobile. In both the novelisation and the captions the name is rendered entirely in lowercase ("vertacine").

The B.E.A.S.T. Glove's name first appeared on the box art of a MEGA Construx Kong set.

The opening confrontation between Godzilla and Charybdis amid Rome's famed landmarks, DNEG's fusion of dynamic creature animation with sophisticated FX work and digital reconstructions of the Colosseum and Piazza Venezia compelled the animation team to stage large-scale devastation while keeping visual coherence within a recognisable real‑world location, senior VFX supervisor Paul Franklin said of the sequence, "we had a major set‑piece set in Rome that opens the film, where Godzilla squares off against a monster called Charybdis, which is a gigantic spider‑lobster creature. We also dedicated a lot of time to studying how places like Rome are photographed and how to present the architecture in its best light. There is a great deal of plate photography in that sequence — live‑action photography from the location — but quite a bit of it is created on the computer. You want to capture the character of what you see in the live‑action but interpret it in a creative and stylistic way. So that was pretty important."
