Continuity mistake: During the first gunfight between The Gunslinger (Yul Brynner) and Peter (Richard Benjamin), The Gunslinger is seen being shot in the middle of the body from the back. But, when you see him a second or two later, the shot is well over on his right side.
Continuity mistake: At the end when the gunslinger is on fire for quite a while most of him and his clothes are burned. Later when he falls off the stairs and gets up without his face and then short circuits, most of his shirt, belt and trousers are in pristine condition.
