Continuity mistake: Heyes is shot from the right and falls from his horse, grazed on the right side of the head. When he's recovering, however, the wound has moved to the left side of his head. (00:13:00)
Revealing mistake: Sam, the third victim, is shot and killed while driving his wagon out of town. We see a long shot of him riding away, then we hear the rifle firing. But the camera lingers a bit too long after that - just enough for us to see the wagon continuing on its way, with a perfectly healthy Sam still at the reins. (00:16:40)
Visible crew/equipment: Curry emerges from the pond into bright sunlight, and the distinctive shadow of the camera is visible against his white shirt. (00:20:20)
Factual error: The dresser mirror in the saloon girl's boudoir is ringed with photos - but they're 20th Century color Polaroids. (00:24:00)
Visible crew/equipment: When the sheriff and his deputy knock on Rachel's door and she opens it, the glass shows us a studio reflector and some of the camera crew. (00:39:30)
Continuity mistake: The rifle Curry slings to his saddle when he sets off after Jake disappears during his journey, then reappears just in time for him to use it in getting the drop on Jake. (00:42:40 - 00:44:25)
