Factual error: The "brick mansions" are in Detroit, but when the surveillance satellite footage is shown, the initial, close-up skyline shown from above is of San Francisco. Then as it zooms out it's looking at Chicago. (01:04:00)
Factual error: In the scenes where Gardner is messaging his Earth based female friend Tulsa from his Mars home, their communication is shown as being in real time. In truth, there would be minimum of a 4 min lag between messages due to the distance. (00:24:00)
Suggested correction: The tech is supposed to be highly advanced. This is at least kept consistent throughout the film as all communication between planets is in real time.
There is no tech that can alter the laws of physics that we know of. The near future setting of the film limits the scope of what's feasible.
Factual error: In World War 2 London, Pink is shown playing with an aeroplane model - an Avro York. The earliest available plastic model kit of this aircraft was produced in 1967. Inaccurate model aside, it begs the question of what a kid of Pink's age would be doing with a plastic model kit during World War 2 anyway.
Factual error: When Glass saves the Indian girl from the Frenchmen the flintlock pistol he gets off the Frenchman fires multiple times without reload, as it does later while being chased by the Indians.
Continuity mistake: The morning after Christian brought a drunk Ana back to his hotel room, she is sitting in bed eating some breakfast. The piece of toast she is holding keeps changing shape, having one bite taken out of it, then two, then one again in a different pattern.
Visible crew/equipment: When Charlie walks down to the front of the class in the hanger, Jester is the only one at the front. Look at the reflection of Maverick's glasses, and the reflection shows lots of people standing in front of him, likely film crew. (00:26:20)
Continuity mistake: When Richard and Francoise are making love on the beach. They begin kissing deep under the water and continue all the way to the top. When they reach the surface they can stand up in the water which appears to be waist-level.
Continuity mistake: When Danny gets shot at the end of the film, his paper flies out of his hand. But the very next shot of him shows that the paper is still in his hand being held over his head while he falls backwards. In one of the following shots the paper is back on the floor, but it's on the opposite side it should have been when it flew out of his hand. It's all shown in slow motion and it's very obvious.
Other mistake: Why did Merrimen have to show Donnie how to use a M4? Earlier in the movie it was stated that Donnie was in the Marines for a short time.
Suggested correction: Only Big Nick and the other cops knew Donnie had served. They had his records pulled up. Donnie never told the other crew so he could look inexperienced enough to not run the whole show. It made it easier to double cross both sides later. Donnie played the fool to get the upper hand.
50 cent told Merrimen "he was a marine for a minute" also Donnie has an Eagle, Globe and Anchor tattoo (Marine Corps).
Plot hole: During the later parts of this movie there is much talk about 'continental displacement' and this appears to be happening in the film. The Earth's crust is falling apart because of the heating of the inner core, and all the cities seems to be falling apart since the ground can no longer hold them. When our cast finds themselves surprised to be already over China when they figured to be over the ocean, it is explained that Asia has actually moved from where it was. If this phenomenon is taking place globally, how come the monks in China don't seem to have been disturbed at all? In fact the bell the monk rings as the ocean approaches hasn't even been shaken. The arks are built in between the mountains, but the mountains are apparently fine. Shouldn't they be falling like the rest of the crust?
Continuity mistake: In the 'Gaston' song sequence, near the end, Gaston is sitting in his huge antler chair with Lefou. In the wide shot, there is a bear rug behind the chair. The camera does a close up of Gaston, then in the next wide shot, the chair is on top of the bear rug. Also, after this, Gaston gets up off of the chair and in the next shot, both the chair and the rug disappear completely. (00:29:20)
Visible crew/equipment: After he gets beaten up by his father, Ricky looks in the mirror. On the left edge you can see a bit of the camera, then it moves away. (01:10:10)
Continuity mistake: Arnold goes to the gay bar to solicit the help of the guy he saved at the beginning of the movie. The guy is wearing a white shirt and a vest black/gold lamay. During their conversation he takes off the vest, then it cuts to another bartender. When it cuts back the guy has the vest on, another shot and the vest is off again. (00:08:05 - 01:10:50)
Continuity mistake: When Adam Banks is playing in one of the games, he scores a goal and his teammates on the bench stand up and cheer when he scores. Problem is, Adam Banks is on the bench too.
Revealing mistake: Leonardo DiCaprio blinks after he dies. (01:50:28)
Revealing mistake: Near the middle of the movie Samantha Mathis is walking across the high school campus. The name of the high school in the movie is "Hubert Humphrey High School, " but behind her, above the library door, a sign says "Saugus High School Library". Shows better in 4.3 aspect. (00:31:45)
Plot hole: Suzie pulls out some of her teeth with a pair of heavy pliers. This would leave conspicuous tool marks on the teeth that would be visible to the naked eye, let alone under forensic examination. The conclusion would be that Suzie is missing, not dead, and the whole plot would unravel from there.
Deliberate mistake: Leaven spends too much time thinking about if 645 and 372 are prime numbers to be believable. But she knows the factors of 649 and the result of 26 to the power of 3 almost immediately. Plus anyone with any maths knowledge whatsoever would know that any even number (or one divisible by 5) can't be prime, so 645 and 372 could be dismissed without even thinking about it.
Other mistake: During his conversation with the landlord of the pub he ends up staying in, Sergeant Howie makes it clear that he did not intend to stay on Summerisle overnight, that he had been delayed and so needed accommodation. Makes you wonder why he packed his pyjamas. He's wearing them when Britt Ecklund does her famous naked song and dance routine, and they are not new so we know he didn't buy them that day. When he arrived he didn't even think he'd be on Summerisle for more than a few hours - we don't see him with so much as an overnight bag.
Revealing mistake: After the woman is strangled and the people come in trying to find the little kid, the dead woman is clearly seen blinking. (00:11:25)
