Continuity mistake: In the scene where Glen Ford shoots the stagecoach driver dead, the body falls to the ground. Glen Ford gives the order to put the "dead" man on the saddle of a horse. When the men lift him up, the "dead" man puts his right hand up onto the shoulder of one of the men.
Continuity mistake: In the first few scenes in the lobby of the Contention City Hotel, the clock is silent. In later scenes, it is ticking quite loudly.
Factual error: The train's locomotive has a steel cab, an electric headlight, and other modern applications. Overall, it more closely resembles an early 20th century steam engine than that of the 1880's, when the movie supposedly takes place.
