Factual error: Eazy-E sports a black Chicago White Sox hat with a white logo early in the movie in 1986, but the logo didn't officially rollout until 1991.
Plot hole: They found seminal fluid left in Caroline Polhemus. Why didn't they subject it to DNA testing, which would have been a powerful indicator of Sabich's guilt? Fertility (or otherwise) has nothing to do with it - as well as non-motile sperm (which contain DNA anyway) the seminal fluid would contain discarded skin and blood calls in abundance. DNA testing was first used in a criminal case in 1985 and was in fairly common use by 1988.
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.
Factual error: A map in the office of Policeman Pierce Brosnan showing the "Hillside Lake" is Lake Constance (Bodensee) in the south of Germany. (01:11:00)
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)
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)
Revealing mistake: When John picks his wife up at the airport, it's raining. But look at the people around outside, they are in T-shirts, in the sun, and not getting wet. Obviously the rain is being sprayed on the car.
Factual error: During the scene where Mozart is being carried away in his coffin by horse and cart there is a brief shot where he is being taken down a muddy path and a farmer is seen with his cows. If you look closely to the left side of the screen you can see a large overhead power line. If you look even more closely you can even see the wires coming out of the pylon. The movie is set in the 18th century and obviously it should not be there. (02:50:50)
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: No actor is going to secure a recurring speaking role in a soap opera unless a comprehensive insurance policy has been secured. (This applies to feature films, too.) This will inevitably involve a medical examination. Mr Dorsey's plans are going to become dreadfully unstuck the minute he drops his y-fronts in the doctor's surgery. (No, he can't find a compliant or bribeable doctor - the insurance company will always use their own people.)
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.
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?
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).
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)
Factual error: Ashley Judd is convicted of murdering her husband for the insurance money and that would make it a first degree murder charge (first degree meaning she planned the murder). Because of that there is no way she would have been eligible for parole after just 6 or 7 years.
Suggested correction: It's never stated that she was charged with 1st degree murder, nor that she killed her husband for the insurance money. It was only brought up in trial as motive. Nick's accident was ruled "wrongful death" and the fact she did get paroled further show she was never convicted of 1st degree murder.
And what about the phone call from prison the Libby makes to Angie, and Angie says she "was just about to call her" or she tried calling her like how the heck can you call someone in prison!?
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)
