In the bowling scene when Tyler is attempting to pick up the split, as the ball goes down the alley the scene is first in slow motion and then in regular motion. As the ball reaches the pins and the film changes from slow to regular, the ball jumps back a couple of feet.
Towards the end of the film, there is a long line of the characters waiting inline at the bathroom of The Eagle bar, and they are entering the bathroom one by one. However when Roger goes in, the bathroom is revealed to be a multi-person bathroom, ie multiple stalls and urinals, it was not a single person bathroom as was implied by the line and one by one entry.
