Revealing mistake: When the Senator is being killed by Travolta in the river, we can see some shots of his assistant before his car explodes. If you watch closely just half a second before the frontal shot of the explosion, you can see in the driver's seat a dummy with a green face.
Continuity mistake: In the car chase scene Gabriel goes to get the gun from the boot leaving his door open then he starts to fire the gun with the boot open later the view switches and both are closed.
Other mistake: When Stanley is driving the Tuscan TVR while trying to escape the assassins, each close-up of the dashboard readout reveals that the speedometer is actually at 0. (01:01:00)
Continuity mistake: When we first see the interview room with Axel Torvalds in, a detective is standing behind him and his lawyer. He then goes to lean on the desk with one hand remaining on his hip. In the next shot he's put both hands on the table. (00:18:10)
Continuity mistake: During the scene in the nightclub where John Travolta first tells Hugh Jackman to hack entry in 60 seconds instead of 60 minutes, Vinne Jones is holding a gun to Hugh's head. As the shot switches back & forth during the scene, you see Vinnie is holding the gun two handed in 1 shot, & single handed in the other. This is repeated a few times as the shot changes.
Continuity mistake: When Stanley is hitting golf balls from the top of his trailer, we see a close-up of his left hand placing the ball on the tee. In the next shot, he's still leaning down, but now it's his right hand which has been placing the ball.
Revealing mistake: At the end of the car chase scene between the TVR and the SUVs, the last SUV crashes into a wall, explodes and flips over into a diner. During the explosion you can see a piston pushing the car over.
