Other mistake: Near the end of the movie, after the cops storm the bank, all the cops walk into the vault, and as the camera follows them into the vault, you can hear the camera hit the metal vault door, and visibly see the camera shake from hitting it. (01:38:15)
Continuity mistake: Det. Farzier is going over the inventory list and the page, where locker 392 is missing. This page of the list starts with locker #385 (size 3x10) and going further (5x5, 10x10, 4x10, 3x10, 3x10, 4x10), skipping 392 to 393 (size 4x10). A few seconds later he takes a second look at the page (close-up shot), but this time it already starts with locker #378 and the sizes of the numbers seen earlier, starting at 385, do not match up anymore (e.g. 391 is now size 5x5 instead of 4x10). (01:44:26)
Other mistake: At 1:44:31 a close-up of a bank safe deposit records document shows box sizes that don't match the sizes of the boxes themselves shown at 0:58:41 and 1:55:21. The document shows box 378=3x10, 379=5x5, 384=5x5, 388=3x10, 396=5x5 but the boxes themselves appear to be 378=5x5, 379=5x5, 384=3x10, 388=3x10, 396=10x10. (01:44:30)
Continuity mistake: As Dalton stands inside the bank vault staring at the cash, the scene jumps from a wide, distant shot, to medium, to close-in, just outside the cage. Another robber stands just outside and between jumps his gun position shifts from relaxed to raised to relaxed again.
Suggested correction: Whilst this is true, I don't think it is a continuity mistake. It looks to me like it is intended to suggest the passage of time between each of the three shots.
Continuity mistake: The handwriting and capitalization written on the desk drawer sent by the robbers containing their demands changes when Detective Frazier discovers that it's bugged. For example, "SemTex" changes to "SEMTEX" and "CAMeras" changes to "camerAS".
Continuity mistake: In one scene, Clive Owen takes a piece of pizza and a bottle of water to the young boy who is being held hostage. The piece of pizza stays intact throughout the scene even though the boy is obviously eating it.
Revealing mistake: During the final conversation between Detective Frazier and Arthur Case, Frazier holds up his hand with the ring on his middle finger. It is pretty obvious that the hand was inserted into the scene in post production; the hand doesn't move in a natural way and simply looks out of place.
Suggested correction: Really? I don't see anything unnatural in the hand's movement at all. Doesn't look at all obvious to me that it was inserted in post-production. After all, Frazier refers to "this ring." They will want it in shot so I'm sure they made sure Washington held it in shot.
Yes, really. Look again. Look at how it moves down and vanishes out of the frame. No human hand moves like that! They didn't have Washington hold it up for the shot and it was inserted later as a pickup shot. See this IMDB goof entry for more details: "During the final conversation between Detective Frazier and Arthur Case..." "a picture of a hand with a ring on the middle finger was inserted into the scene - first moving up into the shot, and then moving down off screen."
Revealing mistake: When Detective Frazier enters the bank and tries to get the jump on Dalton Russell, they get into a struggle and fall down the stairs. As they fall down, look at Detective Frazier's head. It is supposed to be bald, but it suddenly has a full head of hair. It's quite obviously a stunt double.
Other mistake: When Washington went back to his room at the end just before he pulls the diamond out of his pocket. He unloads his Glock. The magazine doesn't have any bullets in it and there wasn't any noise of a bullet falling out of the chamber as he moves the slide back.
Revealing mistake: When the policemen are looking at the security camera tapes, it is obvious that one of the infrared rays doesn't come from the lamp. It seems to come about 30 or 50 centimeters from the left.
Factual error: In the ending credits, in the cast section, the word "Mobile" is misspelled as "Mobil" five times.
Audio problem: Towards the end of the movie, Jodie Foster talks to Christopher Plummer in a bathroom. He starts to talk about his past in World War II. His lips say fifty years ago, but the words you hear are sixty years ago.
Character mistake: The bank robbers send out a hostage and put a drawer around his neck with a note. The drawer is bugged and the bank robbers can monitor the police. The police just leave the drawer lying around on the table for half of the movie inside their mobile headquarters. This drawer should be in a forensic laboratory being checked for fingerprints and similar.
Continuity mistake: During one scene, Clive Owen's female accomplice opens the safety deposit box. Then she moves and Clive Owen steps up to it. She moves behind him, but in the next shot she's next to him.
Factual error: At one point, Detective Keith Frazier gives orders to an Emergency Services Captain, who obeys them. In the real NYPD, a captain outranks a detective and would never take orders from his subordinate.
Continuity mistake: After the Detective wrestles with Dalton, and he pulls his revolver out, and he cocks it and says "you just crossed the fucking line", the next shot shows the revolver is not cocked.
Continuity mistake: Near the end, when Jodie Foster barges in to see Christopher Plummer at the barber, she has a tote bag. She sits in an empty barber chair and places the bag on the floor before speaking to Plummer. As she rises to leave, she picks up the bag, but when the shot cuts to her just as she walked out the door, she is no longer carrying it. Both hands are clearly visible as she buttons her jacket, and the bag is not in either hand, nor is it slung over her wrist or arm. It is simply not there. This particular shot may only be visible in the theatrical and widescreen DVD versions, and not in an edited and "pan and scan" format.
