Visible crew/equipment: When Festus has put a false article regarding a gold strike and the people are rushing out of town, there is a shot in which the view is head on to the street full of riders and wagons as people are leaving town and the roof of the set is visible over the street instead of sky.
Other mistake: Jeb throws a big party at Miss Kitty's saloon and pays for it with a poke full of gold. Sam the bartender weighs the gold and says it is worth $420. Kitty later gives the poke of gold back to Jeb and tells him, "The party is on me." Sholo, Jeb's mining partner, says, "There's $700 worth of gold there. "
Visible crew/equipment: During the sequence with the fire going on in the town, there is a shot with several guys on horseback riding parallel with the camera. They're talking while riding. Look at the lead horse. The shadow of the boom mic is extremely obvious. (00:15:45)
