Character mistake: In the saloon on the way to Sweetwater, where Harmonica meets Cheyenne and his gang for the first time, Harmonica grabs one of the men's coats and looks at it, saying "I saw three of these dusters a short time ago. Inside the dusters there were three men. Inside the men there were three bullets." Actually, while the movie starts off with the three men at the train station wearing dusters, in the shootout scene, the black cowboy is no longer wearing a duster. Harmonica would have only seen two dusters. (00:41:50)
