Continuity mistake: Due to the insertion of stock footage, Heyes and Curry ride the short distance to Clem's house on three different sets of horses.
Continuity mistake: Heyes and Curry both lose their hats when they jump from the riverboat into the water and swim ashore. There's no time to go back and fish the hats out, even if they could find them, but by the next episode and for the rest of the season, they somehow have the same hats back again. (00:41:00)
Continuity mistake: Near the end, Heyes leaves the house with his gun strapped on, but when the camera angle reverses, he's not wearing it. It's back in the next shot, though.
