Continuity mistake: A wheezing Deputy Treadwell races across the street to the saloon to collect a posse. On the way, he's trying to buckle on his gun-belt, but he fumbles it and his gun falls to the ground near the hitching rail. No one picks it up, but he somehow has the gun back in his holster again when he runs out to ride away seconds later. (00:16:25)
Audio problem: In the hotel room, Leslie offers her ring as a down payment to Heyes. He reaches for it and says, "May I?" But as we hear the words, his lips aren't moving. (00:13:15)
Continuity mistake: During the stage robbery, the bandits take everyone's guns, including Heyes' and Curry's. But when they unhitch the team horses and gallop after the bad guys, Heyes and Curry have guns again. (00:03:20 - 00:08:10)
Continuity mistake: Heyes and Curry have waded into the lake to recover the chest, so their pants are soaking wet up to hip level. But just a few minutes later, they're both completely dry again. (00:31:45)
Continuity mistake: The first time Leslie visits Heyes and Curry in jail, they are in two cells right next to one another, Curry lying on a bunk in the cell to the left. The second time she visits to break them out, they are still in two cells next to one another, but the cell with the bunk is on the far left, Curry is the in middle cell, and Heyes is in the cell on the right. When Leslie points her gun at the lock of Heyes's cell door, he takes cover behind Curry, who is suddenly in the same cell with him with no bars between them. When Leslie brings Heyes the letter spike to use in picking the lock, the two are back in different cells with no bunk visible.
Continuity mistake: When they've opened the chest, Leslie pays Heyes $1500 in cash, which he's holding in his hand when the gang of robbers gallops up. In the next shot, Heyes turns and raises his hands, and the cash he was holding has disappeared. (00:31:40)
