Factual error: This movie is set in the pre-Civil War Old West. At about 01:06:50, a slave, who is hoping to be taken to Mexico (where slavery is prohibited), is trying to bamboozle the lady played by Shelly Winters into believing he has vast astrological knowledge. And he points at the sky and mentions Pluto (which hadn't yet been discovered then). (01:06:50)
Continuity mistake: Joe Bass, freshly robbed by the Indians, is asking the slave "You come a long way from home, you ran away?" In his hand is a bottle of liquor with the cork on. Change shot, the bottle is open. New change, and now the bottle is closed again. (00:08:00)
