Continuity: In Barnes' perspective, when the President is shot twice, immediately after this he (the President) tilts his head to the left in response to the agony. However, in Enrique's perspective, he tilts his head right, and this isn't right, since it's the same event but from a different perspective.

Continuity: Several times when we see what's on the black tourist's camcorder, the elapsed time on the bottom corner shows the same time between shots of the screen.

Continuity: During the car chase scene, some of the damage Barnes's car has taken is not there in the wider shots, but you do see it in the close up shots. Submitted by pross79

Factual error: When Quaid eventually catches up with Javier and Matthew Fox's character, he shoots way more shots than his gun is capable of holding without reloading.

Other: When Howard Lewis is recording killing of Enrique through the fence on the bridge, none of fence's wire is seen on the screen of camera.

Plot hole: When the lead Spanish terrorist is speaking to the doorman at the hotel, he speaks to him in English, and the doorman speaks back in Spanish. They are both Spanish, so it's illogical that the leader wouldn't speak in the same language.

Deliberate "mistake": In the point of view of the hispanic cop, he is being lead away by a secret service (SS) guy when the cop hears an explosion, he punches the secret service man but before the SS guy can react, the second explosion goes off. In all the other points of view, the first explosion goes off and there is 30-40 seconds of a break before the second explosion goes off. (Its clear the director needed the cop to have the distraction of the first explosion to attempt to get away, but in order for the cop to escape he had the second explosion go off seconds after).

Plot hole: During Howard's flashback the viewer sees from his point of view the two SS agents who had been following Enrique fire multiple shots at the now revealed Spanish police officer as he was talking to another police officer (Javier) who had just approached him. The scene ends leading the viewer to believe Enrique was killed by the SS agents. However, in the final scene when it's revealed that he was in fact killed by Javier the SS agents significant fire (9 shots I counted) and presence is completely forgotten.

Continuity: At the underpass, when Taylor realizes that Barnes is right behind him on foot, he starts driving away. He's supposed to be speeding away, yet Javier, who is injured, is able to catch up to him on foot with ease.

Revealing: Forrest Whitaker's character has been running after the secret service agents for a while, yet when he stops to film the Spanish cop getting shot, he isn't remotely out of breath.

Factual error: The engine noises coming from the Chevrolet Astra (blue car) are not coming from any engine in that car. Only the Vauxhall and Opel variants of that model got the high performance petrol turbo engines. It's clearly a Chevrolet from the logo on the front and back of the car.
