Continuity mistake: In one scene, Ralph is in a phone booth desperately trying to make a phone call. Ralph is nervous and panicky. But when you look at his reflection on the phone, you can see a big relaxed smile on him. When it cuts back to him, he is still acting nervous and panicky.
Continuity mistake: When Edward and Tracy open the lid of the chest in the tower, Benger puts his hand on Tracy's shoulder and Edward has both his hands on the lid. In the next shot, he now has one hand on it.
Continuity mistake: When Colt Seavers is chasing the villains in the golf cart, the camera equipment on the back of the cart keeps disappearing and re-appearing.
