Beetlejuice Beetlejuice goofs

After Dolores has finished putting herself back together with a staple gun, viewers notice the staples on her face are spaced about 1.5"-2" apart, totalling 10 from chin to forehead. Later, as she walks towards the camera (apparently her only role in the film), she seems to have roughly 21 staples on her face, spaced approximately 0.5" apart.

At 17 minutes 55 seconds, a scale model of the town is visible, with the car having smashed through the right-hand side of the bridge. In the original Beetlejuice film, the vehicle broke through the left-hand side of the bridge.

At Charles Deetz's funeral, one of the gravestones can be seen swaying slightly in the breeze, implying it may be made of polystyrene. Another gravestone moves with little effort when Wolf Jackson lightly touches it as he and the police prepare to raid the church.

In the opening title sequence, as the camera sweeps over the red-covered bridge at the two-minute mark, two white folding signs can be seen on the left of the frame. They were put in place to direct traffic during filming. The behind-the-scenes featurette titled "The Juice is Loose" shows the signs read "SLOW 5 MPH" and "LOCAL ACCESS ONLY".

Saturn is depicted as visible from the surface of its moon Titan. Titan's dense atmosphere, consisting of nitrogen (94.2%), methane (5.65%) and hydrogen (0.099%), is so hazy that it permanently obscures the view of Saturn (and Titan's surface when the moon is observed from space).

At roughly one hour and seventeen minutes into the film, Lydia's late husband (who is also Astrid's father) congratulates them on surviving Titan's radiation. In reality, Saturn's radiation cannot penetrate Titan's dense atmosphere sufficiently to pose a threat to any life on its surface.

The living Lydia and Astrid land on Saturn's moon Titan and remain apparently unharmed, acting as though they were on Earth. In reality, with gravity at only about 14% of Earth's they would be more likely bobbing about rather than walking. Although a human would not die instantly on Titan, its freezing temperature of 290 degrees Fahrenheit would confine any survival there to just a few seconds of intense shivering. Additionally, Titan's atmosphere is not breathable by humans.

Lydia’s husband appears as a civil servant in the afterlife, which under the rule set out in the earlier film implies he took his own life. Yet, lines of dialogue in two separate scenes indicate his death was accidental.

A newspaper in the film mentions that the relevant authorities frequently misclassify non-suicide deaths as suicides, which could account for his role as a civil servant. Also, viewers are not given a complete account of his death; it remains possible he deliberately entered a situation where death was very likely — in effect, a suicide mission.

Astrid calls Marie Curie a "French physicist". This is incorrect. Marie Skłodowska‑Curie was born in Poland and moved to France as an adult. She pioneered research into radioactivity and discovered new radioactive elements, one of which she named after her homeland — Polonium. Marie Skłodowska‑Curie was Polish by birth; although she later became a French citizen, she was not French by origin.

Lydia tells Astrid that Rory plans to be married at midnight on Halloween night. Technically that would be 1 November, since midnight marks the start of a new day and so would no longer be Halloween. However, many people use “midnight” for a given date to mean 11:59 pm.

The claymation Charles is ambushed from behind by the shark and seems to be completely swallowed. When he later turns up in the waiting room, his upper torso and head look as though the top of him has been bitten off.

The flashback never shows the aftermath of the shark attack, so the sequence offers nothing beyond a bloody appearance.

During Lydia's Ghost House show, she speaks with a married couple from Wisconsin, yet neither of them, referred to as "Wisconsinite", speaks with a recognisable Wisconsin accent. A Wisconsin accent is generally indistinguishable from a standard General American accent. There is a "north-woods" variant, heard for example on "The Manitowoc Minute," but Lydia's guests do not use that accent either.

If Beetlejuice was poisoned by Delores, he couldn’t have been Juno’s assistant as the 1988 film indicates; the rules state only those who died by suicide can become civil servants. A newspaper in the film points out that the authorities often misidentify non‑suicide deaths as suicides, which is why some of the deceased end up serving as civil servants. Alternatively, Beetlejuice may simply have been inventing the story.

In the original film it’s made clear that time passes markedly differently in the Netherworld than in the real world; by contrast, in this instalment the characters simply move between the two with no apparent lapse of time.

Lydia possesses a supernatural gift for communicating with the dead, yet it's never explained why she cannot see or hear her late husband — Astrid's father — who is plainly deceased and employed as a civil servant in the afterlife.

Astrid refusing to accept Lydia's claim that she can see ghosts is wholly at odds with the original film. By the end, Adam and Barbara had grown to be like family to Lydia and were content to share their home with Charles and Delia. It's extremely unlikely that Astrid would dismiss them all as frauds, or that no photographs or recordings would have been made over the years of their supernatural antics — for instance Adam and Barbara levitating Lydia and rearranging the furniture. Lydia enjoyed photography; it was how she first realised Adam and Barbara were spirits, after taking Polaroids of them draped in sheets and noticing they had no feet.

When Delia dies, she bypasses the entire afterlife procedure and is permitted to go straight to the Great Beyond, even though the film makes clear that the afterlife is so bogged down in bureaucracy that the deceased must first abide by rules on Earth before reaching their final destination. Even whilst she is in the Netherworld, she and Charles are simply allowed to roam and board the Soul Train without undergoing any processing.
