Old Man Clanton actually died prior to the gunfight and probably never met any of the Earps.
Doc was a dentist, not a surgeon, and survived the shootout.
The two return to Tombstone, where after being questioned, Chihuahua reveals the silver cross was actually given to her by Billy Clanton.
During the interrogation Billy shoots Chihuahua through a window and takes off on horseback, but is wounded by Wyatt. The chase leads to the Clanton homestead, where Billy dies of his wounds.
Director John Ford said that when he was a prop boy in the early days of silent pictures, Earp would visit pals he knew from his Tombstone days on the sets. So in My Darling Clementine, we did it exactly the way it had been." Ford was working on his last silent feature, Hangman's House, in 1928, which included the first credited screen appearance by John Wayne.
"I used to give him a chair and a cup of coffee, and he told me about the fight at the O. Wayne later told Hugh O'Brian that he based his image of the Western lawman on his conversations with Earp.
The screenplay is based on the fictionalized biography Wyatt Earp: Frontier Marshal by Stuart Lake, as were two earlier movies, both named Frontier Marshal (released in 19, respectively).My Darling Clementine is regarded by many film critics as one of the best Westerns ever made.In 1882 (a year after the actual gunfight at the O. Corral on October 26, 1881), Wyatt, Morgan, Virgil, and James Earp are driving cattle to California when they encounter Old Man Clanton and his sons.The threesome soon learns that Tombstone is a lawless town without a marshal.Wyatt proves the only man in the town willing to face a drunken Indian shooting at the townspeople.In their later years, Wyatt and Josephine Earp worked hard to eliminate any mention of Josephine's previous relationship with Johnny Behan or Wyatt's previous common law marriage to Matty Blaylock.
