Continuity mistake: After the credits, Barbossa is shown lying on the treasure pile. The Aztec chest is up at the top and the lid is closed and straight. (It was also shown with the closed lid when Jack asked Will to drop him off at his ship.) Then, in the last shot, when the monkey jumps up onto the chest, the lid is on the Aztec chest, but it is partially open now.
