I think there’s some confusion:
https://en.wikipedia.org/wiki/Wyatt_Earp
Director John Ford said that when he was a prop boy in the early days of silent pictures, Earp would visit pals on the sets he knew from his Tombstone days. “I used to give him a chair and a cup of coffee, and he told me about the fight at the O.K. Corral. So in My Darling Clementine, we did it exactly the way it had been.” When Ford was working on his last silent feature Hangman’s House in 1928, which included the first credited screen appearances by John Wayne, Earp used to visit the set. John Wayne later told Hugh O’Brian that he based his Western lawman walk, talk and persona to his acquaintance with Wyatt Earp, who was good friends with Mix. “I knew him ... I often thought of Wyatt Earp when I played a film character. There’s a guy that actually did what I’m trying to do.” [/snip]
Tom Mix was one of Earp’s pallbearers, and wept openly during the service. There’s an oddball movie called “Sunset” starring James Garner as Wyatt Earp and Bruce Willis as Tom Mix. Mix later died in a car crash — he was a big fan of the Duesenberg brand, and his death car was repaired and later restored, and is still in use of a private owner. Those things were built.
Oops, I introduced more confusion — it wasn’t a Duesenberg, it was a Cord, which is rarer. At the Greenfield Village auto museum, there’s one of each, and they’re parked next to each other — basically, one of the nexi of the universe.
Interesting. Also Tom Mix had special tires made for his car that would leave the initials “T.M.” in the dirt roads. Mix had special heavy plywood luggage made for him and he was driving one day and came on a road construction site and hit his brakes. The luggage came forward and hit him in the head killing him.
