Revealing mistake: The opening shot of the movie shows a rabbit hopping up from the bank of a road and then being hit by a car. You can, however, tell that the rabbit is not real because as it moves up the bank, none of the grass moves as the rabbit bounces through it. (00:01:05)
Revealing mistake: When Jim and Grace are driving along in the stolen sheriff car, away from all the police cars and Ryder, the car's back window is shot and completely shatters and fragments. Yet in a following shot we see Jim look into the rearview mirror, and he gets a clear view of behind. The back window was shattered and cracked however, so he shouldn't have got that nice clear view.
