The 2003 film Wrong Turn is the sole instalment in the series that contains neither sexual content nor nudity.
Eliza Dushku performed many of her own stunts for the film.
As the four fled the cabin after rousing the mountain men, Desmond Harrington fractured his right ankle after landing on the far side of a log. This made filming certain scenes particularly difficult after his left leg is 'shot' and he has to limp on his right leg.
Several cast and crew members developed extensive poison ivy rashes during filming after chairs were placed in an area initially thought to be a clump of weeds, which was later realised to be a patch of rash-inducing plants.
Emmanuelle Chriqui dislocated her shoulder while performing a fall through the trees. The production audio included in the cinema release sound mix captures the audible pop of her shoulder.
In one of the film's closing scenes, Eliza Dushku actually set actor Julian Richings (Three Finger) alight.
The film's female lead, Jessie Burlingame, was named for the protagonist of Stephen King's novel 'Gerald's Game'.
Several years before the production of Wrong Turn (2003), cult horror filmmaker John Carpenter and screenwriter James Nichols penned an unproduced horror‑thriller script titled Prey, whose plot strongly resembles both Wrong Turn (2003) and The Hills Have Eyes 2 (2007). Carpenter characterised Prey as a blend of Deliverance (1972) and The Texas Chain Saw Massacre (1974). The narrative follows three young women who travel through the woods to get to a mountain but are captured by a family of inbred locals, whose patriarch intends to use the women for breeding. At one point the sole surviving woman escapes and, as in the film, the family give chase through the woods; they are ultimately killed by her during the pursuit and the family patriarch is captured and imprisoned.
For the duration of the film, Eliza Dushku wears a white T-shirt bearing the Albanian double-headed eagle emblem.
In the original screenplay the characters were written to be in their late twenties, but they were aged down so the film would appeal to younger viewers.
Advertising for the film was kept minimal because the MPAA judged that the majority of television spots and trailers were 'too intense' for viewers. Even the adverts that were broadcast were heavily cut.
Unlike the sequels, the first film contains no nudity. There were attempts to add nude and sexual scenes typical of the genre while screenwriters such as Adam Cooper, Bill Collage and others worked on various drafts of the screenplay. For example, the opening was altered in one version so that Rich and Halley bathed naked in a river before being killed while having sex on land; Francine and Evan were to have sex in the woods rather than beside their crashed cars; Jessie's clothes were intended to be torn off while she was tied to a bed; and several similar scenes were ultimately omitted from the finished film.
Although credited only as a producer, make-up master Stan Winston was instrumental in designing the Mountain Men, most notably Three-Finger. This was the penultimate major horror picture he worked on before his death in 2008, aged 62, and it represented the third slasher film he contributed to after uncredited work on Friday the 13th Part II and Part III; on the latter he was a principal designer of horror icon Jason Voorhees's original hockey mask and of Jason's mongoloid appearance in those two instalments.
Director Rob Schmidt says in the audio commentary that he regards this film as his own personal tribute to seminal works such as The Texas Chain Saw Massacre (1974) and The Hills Have Eyes (1977).
Death toll: 10 (Rich Stoker, Halley Smith, Evan, Francine, Scott, Carly, a state police officer, One Eye, Saw Tooth, a deputy sheriff)
Chris's vehicle was a 1967 Ford Mustang.
In the opening credits a preacher can be heard on Chris' car radio saying "If you plant your seed into your own kin, you anger God." This serves as foreshadowing, as the film centres on inbred hillbillies.
During pre-production McElroy decided to abandon the idea that Chris Flynn's group of victims were adults in their late twenties in order to appeal to the teen slasher-horror audience. He made Jesse Burlingame, her best friend Carly and the other friends 19-year-olds, portraying them as first-year university students. The change was prompted by the scripted opening of the film in which a rock-climbing teenage university couple, Halley and Rich, are subsequently killed by the Mountain Men.
The film's screenwriter Alan B. McElroy also authored the script for the 2021 reboot Wrong Turn (2021).
In October 2020 the website Mr. Skin published a list of the top ten horror series with the most female nude scenes. The list includes Witchcraft (77), Friday the 13th (49), Hellraiser (24), Wrong Turn (17), Piranha (16), Hostel (14), Silent Night, Deadly Night (14), Halloween (14) and Amityville (9). There is no nudity in the original Wrong Turn film, although the sequels feature a substantial amount.
The pick-up truck driven by Saw-Tooth, One-Eye and Three-Fingers is a 1948 Dodge B-Series.
The car belonging to Francine's mum was a 1989 Land Rover Range Rover Series I.
In the original 2002 screenplay, Chris Flynn's role was named Adam.
For the decapitation sequence, make-up effects artist Shane Mahan and director Rob Schmidt trialled the technique to prove it would work. Mahan relates that he actually went out into the woods with a video camera and a volunteer as the actor and "chopped" at her mouth for about an hour. "We got what we need to do. That gave a comfort level to the director, and it gave a comfort level to me because I could say, 'Okay, this is going to work.'" Mahan said. Once they had the chop figured out, they planned how Carly's body was to fall away following the axe to her mouth. The solution required a fake hollow tree built on set so the actress could put her body through it, leaving only her head sticking out with the prop axe in her mouth. The audience would see only the top of her perched on the axe embedded in the tree and no body beneath. The make-up artists painted Emmanuelle Chriqui's chin black so the camera wouldn’t pick up that part of her head. They also made a low-cost floppy rubber moulded body to drop. When the camera zooms to Carly's eyes, the pupil dilates — this was a digital effect layered over the actor's real eye. Then, as the camera tilts up, the body falls. The falling body was further enhanced and animated digitally for control as it fell through a virtually constructed environment of trees, although the digital body was based on the rubber replica created by Stan Winston studio. "The lesson there was we did that for a third of the cost of what the initial budget was; it was probably a better effect because sometimes having less makes you do more interesting work," Shane Mahan said.
Eric Andre was in contention for the part of 'Three Fingers'.
Make-up effects artist Shane Mahan regards the decapitation sequence as an excellent instructional example, showing why film-makers, actors and artists must collaborate from the page when creating a film. He likens a script to a cookery book: you have all the ingredients and need to put the pieces together to achieve a satisfying outcome. He states the sequence required about three months of planning to fine-tune the complex effects gags and ultimately produce a smoothly flowing scene.
For Carly’s decapitation, when Shane Mahan first teamed up with Stan Winston on the sequence, they initially planned to build an animatronic double of the actress. Each part of the effect was budgeted separately: a full‑body mould, a scan, resculpting, highly realistic skin casting, fabrication of internal mechanisms and a mechanical head. Mahan also explains the rig would have needed to be resettable between takes, which meant a very complicated arrangement on a track — either built into the tree or mounted on a blue‑screen pole. The complete animatronic head would have been attached to a unit with a mechanical device to swing the axe into place and a mechanism to allow the faux body to fall. It was an elegant idea, but the cost was prohibitive for the production. The producer simply couldn’t afford such an elaborate solution, yet they were unwilling to cut the effect from the picture. There had to be another way. Knowing the death planned for Carly would be especially shocking, the producers insisted the scene remain. Mahan worked closely with director Rob Schmidt to identify what aspects of the moment were essential, so they could devise a less expensive approach. Winston, Mahan and Schmidt opted to use a camera trick they’d learned from James Cameron on Terminator 2: Judgment Day (1991) — a whip pan (swish pan) technique. At the top of the shot the camera would track the cannibal’s axe, and as Three Fingers swung, the camera would whip‑pan while the actual prop axe passed under the lens during the move. The pan would continue, effectively masking the cut, and finish on Emmanuelle Chriqui with a prop axe preset into the tree and blood elements dressed on it to indicate it had sliced through her face. Sound effects and the force of the swing sell the illusion — the whoosh and chop are heard, and when the camera lands on Carly’s eye the audience understands she has met a brutal fate. One clear advantage of this method over an animatronic is that it allowed the use of the actress’s real face for the close, so her expression could be directed, achieving a level of realism even an expensive animatronic might not match.
Of the cannibals, One-Eye alone never personally killed anyone.
Kevin Zegers and Lindy Booth went on to portray a couple together the following year in the film (Dawn of the Dead (2004)).
