Other mistake: The date on the tombstone above Annie says that Judith Myers was born November 10, 1947, and died October 31, 1963. That would make her 15 (not quite 16 yet) at the time of death, yet everyone says that she was 17 years old.
Other mistake: In quite a few shots during the film, it is much too obvious that there are no lenses in Harry's glasses, whereas in previous and following shots the glasses have lenses. A couple of instances are: when Harry drinks the Felix Felicis and when Harry kneels beside Dumbledore, at the foot of the Astronomy Tower.
Other mistake: Anna is shown from the front as she ascends an ice staircase inside Elsa's ice castle. There are giant ice pillars to Anna's right and left. They should reflect the side of her face, but instead the reflections show her face from the front.
Suggested correction: That's not how reflections work. The ice walls are about two feet to her side so the reflection would look like it was shot from the front but about 4 feet to the side.
Other mistake: The brief chess game (four moves) shown in the beginning of the movie makes absolutely no sense. For instance: There are no white bishops on the board, but after the human player taps a few buttons, the computer says that he just moved one. Within the two moves described first, the positions of the pieces change completely. In addition, some pieces are now gone and there are new pieces on the board. It's like an entirely different game. The final move is said to have been made with a black rook, which is impossible. In the shot shown before this move, there is not a single position available to that chess piece that would result in an instant checkmate. Nothing in the editing indicates that these few short shots are supposed to be viewed as separate games. (00:04:50)
Other mistake: Leo Crow grabs Anderton's gun and they each fight for control of it. Crow succeeds in forcing Anderton's hand to pull the trigger, killing Crow. The problem is, right after the gun is fired, we see a shot of Anderton with his arm fully extended and with his entire hand holding the entire gun, as if he had aimed and fired the gun himself. Such a sequence of events is at least totally illogical if not physically impossible. (01:44:10)
Other mistake: During the flashback of the soldiers executing the Dachau guards, the soldiers are in a line opposite the guards who are in a line against a fence. The soldiers all start shooting at the same time, but we are shown the guards being mown down by gunfire in succession, like dominoes, rather than simultaneously.
Other mistake: Right at the part where Crazy Ralph is looking in on Paul and Ginny. Ralph hears a breaking of a stick behind him. You can see Jason put the barbed wire up and over the tree. How is that possible? He would have to whip it around the tree, not over it. (00:30:20)
Other mistake: Early in the film, Valerie Barksdale (Hilary Swank) visits Annie Wilson (Cate Blanchett) for a psychic reading. Valerie has been severely beaten by her husband, and her badly black and blue eye is swollen shut. A day or two later she visits Annie again. Amazingly her eye appears to have completely healed, even though the other marks on her face are still visible.
Other mistake: According to the big photograph in their respective offices Bressler and the DA share the same pair of little daughters. (00:17:05 - 01:10:10)
Other mistake: When Prot visits the doctor's house, he thanks the wife and the camera is zoomed into his sunglasses. The reflection of his glasses shows the doctor looking at him, but the doctor is standing behind him. (00:53:40)
Other mistake: While downstairs Vernon hears Hedwig's squawks, as well as Dobby and Harry's exchange in the bedroom upstairs, distracting enough for them all, including the Masons, to take note. The noise upstairs illicits a reaction from everyone, which Vernon explains is a noisy cat. Yet when Harry very noisily chases Dobby down the steps, Dobby slams into the wall and Harry lands with a loud thud (not remotely 'catlike'), Vernon, who stands on the other side of the shared wall, pleasantly continues his story to his rapt guests, who are also not distracted by the noise. To suggest that such loud noises coming from the hallway right beside them would not draw any reaction from anyone, Vernon and the Masons included, is preposterous. (00:06:45)
Other mistake: Speaking to General Hershberg (Michael Moriarty) in his office, Nat Serling (Denzel Washington) implies that it was easily discoverable that the US tank was destroyed by "friendly fire" because the US is the only country which uses "uranium depleted" shells. The correct term is "depleted uranium". Maybe Washington flubbed his lines.
Other mistake: Several close-ups of the business cards of Patrick Bateman and his associates reveal a misspelling of the word "Acquisitions" (the "c" is missing - not a small error, given that this is the name of their department).
Other mistake: Marlowe fires several shots at Art Huck and Lash Canino but if you look at the chamber when he takes the gun out from under the dashboard, there are no bullets in it. (01:41:45)
Other mistake: At Natalie's house, when she is leaving and Lenny is taking a picture of her, the background looks totally different than from what is shown on the picture: the curtains are opened wider, the door is half open, there is a lamp on the left and there is no mirror on the wall. (00:17:10 - 01:20:50)
Other mistake: In the beginning of the film above the box office the date says April 12. When Sidney looks at her watch the next morning it's not even close to that date. (00:00:35 - 00:12:55)
Suggested correction: The mistake is correct, but the watch part has nothing to do with the incorrect date. It is the next day.
Other mistake: In the shot where Ramathorne is at the gun range, about to shoot Mac in the bullet proof cup, he is talking to Foster and Rabbit about how they are going to get in to the Spurbury Police Lockup. If you watch him draw his gun, he moves his other hand down to chamber a bullet, the sound effect is heard, but he never actually pulls the action back on the gun.
Other mistake: In the first scene with Randy telling Jamie Lee Curtis to turn around, the reflection in the TV never mirrors the actual position of Jamie Kennedy. (01:22:30)
Other mistake: Despite being a deadly marksman (only a few minutes earlier in the movie he stopped a bullet directed at him shooting it off the air), Bloodsport snipes several times at the huge kaiju featuring a massive eye in the central part of its body, and never once hits it. (01:51:45)
Other mistake: When Sulu tells Kirk he is coming to help, he states the Excelsior is currently in the Alpha Quadrant. The problem is the the Alpha Quadrant in the Star Trek universe is one quarter of the total Milky Way Galaxy. While technically correct, Sulu giving his position as in the Alpha Quadrant is useless to Kirk in terms of knowing when to expect help. It doesn't matter where Khitomer is in the galaxy. Sulu saying he is in the Alpha Quadrant gives Kirk absolutely no idea of when he will arrive. He could be anywhere from 5 minutes away to 5 weeks away or even further. Remember, it was originally projected to take Voyager 70 years to go from the Delta Quadrant back to the Federation in the Alpha Quadrant.
Suggested correction: The implication is that Excelsior has only very recently crossed the border from the Beta Quadrant to the Alpha Quadrant.
Even if that "implication" were true (and there's nothing dialogue-wise to indicate such) it's still useless to Kirk as to when the expect help. The dividing line between the Alpha and Beta is fully half the width of the galaxy.
Sulu doesn't expect Kirk to deduce where the Excelsior is, he tells him directly that they're unlikely to make it in time, and the reason is that they are "now in Alpha Quadrant" i.e. they were previously not in the Alpha Quadrant, i.e. they're far enough away that recently they were in a whole other quadrant of the galaxy. (I agree it's an awkward line, but it makes sense if you think of it like "I'm now in the U.S." if it's known you already live there - it means you've just returned).
