Revealing mistake: When Don Cheadle slams the lawyer against the wall of the interrogation room, the wall wobbles and shakes.
Other mistake: In the opening coffee shop scene, Gabriel is seen preparing and lighting a cigar. Following this you have several clear shots of both hands above the table. However when he leaves the coffee shop, he has a bomb trigger in his hand, that he implies will go off if he lets go. Where was it when he was preparing his cigar and sipping his coffee? (00:01:33)
Continuity mistake: At the beginning Gabriel and Stan leave the coffee shop. The high up shot (with the helicopter flying past it) shows them walking out into the road, with Gabriel almost at the middle of the road before the shot changes. Then there's a shot of his face then in the next shot from behind a police car they are just leaving the pavement area. (00:04:25)
Continuity mistake: When Travolta and Jackman are chased by the vans, there is a shot from Travolta standing in the car with a gun in his hands. A split second later there is a shot from the front, showing them sitting next to each other in the car. There's no way he could have gotten down so fast.
Continuity mistake: When the government agents try to take out John Travolta and Hugh Jackman, all of the SUV's are supposed to be Lincoln Navigators. Travolta destroys the first two. The third SUV turns left around a corner and it's a Ford Expedition, not a Lincoln Navigator. The scene cuts away and when the SUV is closer it's a Lincoln Navigator.
Suggested correction: That's because he picks it up as he stands.
But the dead man switch was the only thing keeping the police from subduing him. Why didn't they subdue him then?
