Continuity mistake: When Clinch and his gang start to chase Albert, from his house, many of the sheep start running and moving out of the way, even kicking up dust. When the camera angle changes, none of the sheep are moving and there's no kicked up dust.
Continuity mistake: The sheriff wears his badge over his left side, which is traditional. As he is approaching on horse in the final scene of the movie it is still on his left side. Then for a few seconds in one shot his badge is on the right. (01:23:10)
