Factual error: At the end of the movie, the narrator says that Ike Clanton was shot and killed during an attempted bank robbery. Ike Clanton was actually killed while attempting to flee from Detective Jonas Brighton who was sent to arrest him for the crime of cattle-rustling.
Continuity mistake: The scene where Ed says "there's three of them over there" referring to the Cowboys, but when the shot is shown there's actually four Cowboys.
Factual error: Billy Breakenridge in real life was a large man who was almost certainly not gay. He certainly wasn't effeminate as the film makes him out to be and he was known as a good shot and a tough individual.
Continuity mistake: During the gunfight between Johnny Ringo and Doc Holliday, when Ringo falls against the tree, he's wearing a hat. After that, the hat is nowhere to be seen.
Deliberate mistake: When Wyatt comes out of the Oriental and joins his brothers in the street to tell them he's acquired a quarter interest in a game, a herd of cattle is passing them in the street but there's no dust kicked up by the cattle, when in reality there would be a lot of dust on a dry desert street in Arizona.
Continuity mistake: After shooting up the wedding near the start, they are sitting at the table eating the feast. As the camera shows Curly Bill's plate the food on it keeps changing.
Suggested correction: But Hucleberry Finn appeared in Tom Sawyer in 1876 and was a bad influence on, or "made trouble' for Tom.
Not sure what this correction is trying to state, but "I'm you're Huckleberry" was slang in the late 1800's for "I'm your man" and didn't derive from Twain or Huck Finn. Twain uses the earlier slang meaning of huckleberry for Finn, meaning an inconsequential person, to establish Finn is a boy of lower extraction or degree than Tom Sawyer.
