I was watching Gunslingers on the History Channel. It was about Wyatt Earp. In the 20s he was a consultant in Hollywood. It said that he used to spend time in the studio commissary mentoring an extra by the name of Marion Morris - otherwise known as John Wayne. Wayne stated that part of his western characterizations were based on his conversation with Wyatt.
Yeah i saw that on an O.k Corall documentary. I also heard that he was a boxing referee for a while, he was actually ref at a Jack Dempsey fight in the 20s.
