Continuity mistake: In the scene where Banks and Bennie are riding and talking in the old green Chevy (Chapter 4 on the DVD), both of their windows are rolled up. However, all outside shots of her side of the car show the window rolled down. (00:13:00 - 00:14:35)
Continuity mistake: In the scene when Bennie comes back to Banks, she asks him about the papers he's been reading when she sat down opposite him. She then tries to take the papers, but Banks slams his fork into them. In the next shot you can see Banks holding the fork next to his face then, in the next, he presses the fork against the papers again.
