Other: In the last scene under the Highway, when POTUS thanks Barnes for save his life again and when the camera starts zooming out for the end credits, in the traffic driving above the accident there is a Mexican green taxi cab VW Beetle passing through. But, the whole movie takes place in Spain.

Visible crew/equipment: During the car chase the driver's seat on Kent Taylor's car is located on the left side. When he finally gets shot by Barnes and is about to crash, in one of the shots you see a person (in all probability a stuntman) sitting on the right side.

Continuity: When Barnes shoots Taylor and Taylor crashes, we then see a shot of Javier on the floor, with his head on his right arm and his left arm beside it. But, when we see Barnes running to the car, Javier's body is at the lower left of the screen and his right arm has moved to his back.

Continuity: In Barnes' perspective, when Taylor asks him if he saw the shooter, Barnes replies, "No, but I saw something, like a flash of light." In the Howard Lewis perspective, Barnes doesn't say "No, but..."

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.

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.

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.

Continuity: In Thomas Barnes' perspective, when he confronts Enrique, he says, "Don't release him" to the other Secret Service agents. But in Enrique's perspective, Barnes says, "Do not release him."

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).

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.

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.

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.
