Continuity mistake: In the scene that Karen is too afraid to take the clothes and the license plate falls off, there is a shot of the windshield which is close enough to reveal the fake registration sticker made for the era in which the movie was represented. The problem is though that not only is it obvious that the sticker is applied on the outside of the window, but the current sticker (inside the window) is larger than the movie prop and can be seen as a "frame" around the other.

Continuity mistake: When Reggies knocks the boxer out he falls by the ropes. Camera changes and he's moved away from the ropes.
