Continuity mistake: When Gerard is shot by the fugitive in the woods we see him land in the mud and he is laying in a certain position. Next time we see him he is in a different position and the next time after that he is laying the same way we saw him the first time.
Continuity mistake: When they are in the black caprice on the bridge it has no side spotlights, but when they get to the car to the cemetery it has side spotlights.
Continuity mistake: The morning after the plane crash Tommy Lee Jones is sitting on porch of the restaurant while his crew drives up, his pants are rolled up to his knees and he has no shoes on. He then walks inside and buys a T-shirt because he has no clothes. When they hear the FBI Helicopter and all walk back outside Tommy Lee Jones has new pants and shoes on.
Plot hole: After the police arrest Roberts he's flagged for a federal warrant, but Lamb and Barrows don't show up to inquire about him until long after the plane crash. Shouldn't they have been there to pick Roberts up at the police station instead of being sent immediately to a federal penitentiary?
Character mistake: Sheridan (as Roberts) takes a job as a tow truck driver while laying low from the U.N. killings. He claims he had the gun for protection, but he must have realised if he ever had to use that weapon on the job his prints would have been run anyway, so why on earth would he take any kind of job that requires him to need a weapon if he's trying to lay low?
Audio problem: When Noah and the rest of the gang are chasing the Chinese man, Noah is the only one on foot. He sees the Chinese man get in a cab and calls for backup. The rest of the gang arrives seconds later. As Noah gets into the SUV, the sound of the car door closing can be heard before it actually does close (and it never really does in that scene). (01:19:20)
