Continuity mistake: When T and Texas Blood are playing pool, the balls would move around after the stopped. Most notably after T makes the 1-ball. The cue ball is on the opposite side of the dot than the 8-ball and the other two balls are on the other end. In the next shot, the cue ball is on the same side as the 8-ball and the other two balls are now close to the cue ball.
Revealing mistake: At the beginning, when the woman in the flotation seat is paddling backwards, you can see a fishing line attached to the back of seat that is being pulled to help her move backwards.
