Factual error: When Bill and Jason are heading up to Canada (and Lucia is following in her own car), they are driving past several high mountain peaks, and up through a winding valley. Problem is, they started in South Bend, IN and are heading towards Detroit, MI, and that area of the country is notoriously flat, other than occasional hills.
Continuity mistake: Dwayne puts on lipstick, then prepares to put a plastic bag over his victims head. The lipstick disappears just as he is putting the bag over her head.
Factual error: When Jack arrives at a roulette table to replace Matt as the dealer, the roulette wheel is stationary. In UK casinos, it is never allowed to stop spinning at any point while the table is open.
Plot hole: During David Leigh's narrative about Jim's court case, you are shown a number of newspaper headlines concerning the murders. One shows a shot of Locus looking at camera, with the caption 'Did Locus see his killer?' That shot was on the missing film which was found by David Leigh AFTER the murders were forgotten. So how did the paper get the picture?
Continuity mistake: After Paulie is bought from the pawn shop by Ruby, they are out on the sidewalk talking and if you watch in the background, the same red Mustang turns the corner twice in a row.
Continuity mistake: In the marching band scene they all have long shadows, and then suddenly they have no shadows at all.
Continuity mistake: Birdie and Justin are dancing to a song and when it ends the band announces, "We are going to take a short break and leave you with some fine tunes on the jukebox." The song "To make you feel my love" starts, but as they are dancing you can still see the band playing and someone singing.
Continuity mistake: When Sammie wakes up alone in bed, she can see a rapidly moving shadow inside the bathroom. After she sneaks outside the house around to the window, she looks in and we see Sam in the bathtub, masturbating to magazine centerfolds. The problem is that in this second shot, Sam is very far from the door and there is no shadow visible inside the bathroom. In fact, there is not even a light source on the other side of the door from him. Sammie therefore should not have seen a shadow from inside the bedroom.
Continuity mistake: After the photo shoot on the beach the characters are passing around a jug of wine that is almost empty in one shot, but each shot after that it is closer to full.
Continuity mistake: When Shane first gets into Studio 54, he is told to take his shirt off. He pulls it over the top of his head. Then he walks in holding it and even though he never unbuttons it, it is somehow unbuttoned when he puts it on again.
Other mistake: In a prison scene quite early in the film, Patrick Swayze's character is seen playing the 'final move' in a chess game against the warden. As he moves his piece he says, "check mate" but if you look closely and if you have any knowledge of chess you will notice that it is not check mate at all.
Continuity mistake: The young son of the Chinese owner of the violin is near-sighted and his glasses have concave lenses. When he attends the auction as an adult he is far-sighted with incredibly thick convex lenses.
Revealing mistake: When the dog with its legs in plaster is walking across the passageway the first time you see it its back legs are moving although they're supposed to be crippled.
Continuity mistake: After Marnie has installed the talisman, we are given a glimpse of her where she is flipped. She had been resting on the giant pumpkin with her right leg hiked up and her right foot resting inside the pumpkin's left eye. But she is flipped, with her left leg hiked up and her left foot resting in the pumpkin's right eye.
Continuity mistake: Sandra and her strong man are pursuing Jack and Bridget. They almost catch up to them and bang up both sides of their wagon in the car chase. Bridget and Jack escape, with eventually Sandra and company in pursuit a way behind them, tracking them on an alien computer. When they reach the power plant where Jack and Bridget are, their car has no damage at all. (01:18:20 - 01:29:05)
Factual error: When the Spanish sink the topsail schooner bringing supplies to Gibraltar, Captain Foster swims to a floating fighting top. The schooner actually had nothing more elaborate than a crosstrees on both masts.
Plot hole: Batman finds at Belson's home a handwritten list of substances needed for a transplant. Why would Belson, a medical authority in the field that knows those things thoroughly, even write a list down? If it's for Freeze to procure him the material, why would it be at his house and not with him, and when did he even have time to be at home to do that, since he has been kidnapped by Freeze when he was driving on the outskirts of Gotham and taken to the oil rig? If he had time to go home, he at least would have changed clothes, he's still in the tuxedo he wore when he was kidnapped the night before.
Factual error: When the whole of the court go on the "view," it seems as though the bus includes barristers, the judge and members of the jury. In reality, the judge goes with the jury, the barristers are not allowed to.
Continuity mistake: Near the end of the film, the writer seeks out one of the locals, and finds him in a corn field digging up pot plants that marijuana growers are trying to grow in his corn field. There is only one problem: It is supposed to be Spring, but the corn is all brown, thus it really is fall or early winter.
Factual error: In the big professional Latin dance championship scene at the end of the movie, the competitors perform four dances: the samba, the cha-cha, the paso doble, and the rumba. In reality, however, a professional Latin dance championship, regardless of where you go, is almost always a 5-dance event: a cha-cha, a samba, a rumba, a paso doble, and a jive. Rumor has it that a jive sequence was originally supposed to be part of the competition scene but was cut from the final version of the film for unknown reasons.
