Continuity mistake: When Layla's VW has hit the tree, James's truck is pulled up alongside her, facing forwards. When James drives off, his truck is facing the other way but there was not enough time for him to turn around, or any indication that he did turn around (i.e. no sound of a vehicle making a three point turn).
Continuity mistake: When Layla is trying to get away from Clayton in the car chase, she goes to pass a blue car behind a white truck. It cuts to a shot from inside her car and the white truck is there, but no blue car. Another car is coming the other direction and she has to yank the wheel. She should have been creamed by the blue car, but wasn't because it disappeared. (01:32:10)Joel Gordon
Continuity mistake: In the final scenes Al Pacino shoots at Colin Farell until the slide locks back on his pistol. When they make it outside there is a shot of the pistol with the slide fully forward just before they cut to another shot of him releasing the slide from the locked back position to the fully forward position.
