At the end of the bridge scene when they are hanging on the side of the cliff, watch the only other bad guy hanging on the bridge. Indiana and the priest with the shaved head are at the bottom of the rope ladder, and some other bad guy is supposed to be only 5 ft above them. However, when the camera pans out to get a large shot of Indy and the priest, the other bad guy is nowhere to be seen. He should be just a few feet above Indy, but he's not. Then, when the camera goes back in, look who's just a few feet above them! Pretty obvious to me.
