Continuity mistake: From one shot to the next, the six horses pulling the stagecoach change color from black to light brown and back again. (00:07:30)
Continuity mistake: The number of bad guys in Weaver's gang keeps changing. There are ten riders waiting on the ridge. All ten ride down the hill, but only five arrive at the bottom to rob the stage. Seven ride away afterward, but when they head off again to capture Heyes and Curry, there are only six. And when they surround the way station, there are again seven of them. (00:08:00)
Continuity mistake: Heyes is tied to a chair during the assault on the stage way station. But somehow his hair combs itself neatly back after being all over his forehead. A few shots after that, it's messy again. (00:30:40 - 00:33:05)
