Character mistake: The bartender in El Dorado was John Mitchum - Robert Mitchum's real life brother. "Elmer" was the character name of the bartender, as mentioned twice in the first saloon shootout mid-way through the movie and in the movie credits under "Elmer, Jason's Bartender." Robert Mitchum mistakenly calls to the bartender, "freeze it right there, Johnny" (inadvertently using his brother's real name, "John, " as opposed to his character's name, "Elmer") in the final saloon shootout scene. (01:20:59 - 02:00:22)
Character mistake: Mississippi is about to go out the door after some men but Cole stops him. A fight ensues and Mississippi shoots the men with his shotgun. Cole then has an attack with his arm because of the bullet in it. Mississippi says, "Cole, what's wrong?" Mississippi knows that he has this problem so it makes no sense for him to ask what's wrong.
Answer: Earlier in the movie, Colt and Mississippi are doing a nighttime patrol of the town, when men on horses charge at them. There is a shoot out and JP comes running to help. He gets shot in the leg.
That did not address the ankle injury. It looks badly bruised not a gun shot. Can you tell what happened?
