Continuity mistake: When John and Jane are having breakfast on the floor after their huge fight, John eats something out of a tall silver container. He then puts it on the floor next to Jane, who picks it up and sticks a spoon in to get some of what's in there. It then cuts to a closer shot of the pair, and Jane is chewing on the food and putting the container down, even though she didn't put it in her mouth.
Continuity mistake: In the scene where Jane and John are driving the stolen minivan and fighting the BMW's on the bridge, the sliding side door and hatch alternate between shots of being opened and closed. Jane's hair flies around from the door being open, before it is ever opened for the first time. These changes occur between wide and close-up shots, and between Jane's and John's close-ups, throughout the entire scene.
