Continuity mistake: During one of the two explosion scenes you can clearly see the wire that is used to keep the bonnet (and boot) from flying off too far.
Factual error: When John Travolta flies in a helicopter to kill the congressman who is fishing, the caption states that they are in Bend, Oregon, when actually they are in Redmond, Oregon.
Revealing mistake: When Don Cheadle slams the lawyer against the wall of the interrogation room, the wall wobbles and shakes.

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.
