Factual error: In the gunfight in Hasting's store, John Elder fires his six-shooting Colt to a total of thirteen or fourteen times, without requiring - or doing any - reloading whatsoever.

Continuity: When the Elder brothers decide to go see their old ranch and ride out of town, Tom has a noticeably scruffy beard. When they get to the ranch and have a run-in with the deputy, he's clean shaven. They ride back into town with the deputy and he has the beard again.

Continuity: When the sheriff enters the bar to break up a confrontation between John Elder and Curley, he sends John Elder out of the bar. As Curley starts to follow Elder out, the sheriff tells him to sit down and finish his card game. Elder and Curley were standing facing each other for quite a while before the sheriff came. How would the sheriff know that Curley had been sitting there playing cards?

Revealing: In the scence where John Elder is at his parent's gravesite and the sheriff comes up behind him, John Wayne has two guns to make it appear that he draws very fast. Both guns, the one in his hand and the one in his holster are briefly visible as he turns to aim the gun at the sheriff. Viewed on VHS.

Revealing: During John Elder's fight in Hasting's gun store, he ducks behind a counter, and as he pokes out his head, Hastings fires at him. On the counter, the "bullet hole" - containing the powder charge for imitating a bullet impact - is already visible before Hastings fires his gun.
