Continuity mistake: When Imhotep takes Benny as his servant, he holds out some gold items in a very skeletal hand (where he had the gold when he had no pockets is another matter). When O'Connell and friends are leaving Hamanoptera, Imhotep's hand comes out of the sand. You can see that it is either a prop hand, or a crewman's hand in a glove, as it is thicker than it was a few moments before.
