Wyatt Earp had no luck selling his version of the Tombstone events during his lifetime. But shortly after his death in 1929, gangster movies became quite popular. Hays Code and other moral defenders were alarmed and felt these movies were too popular. So they asked Hollywood to stop making movies like “Public Enemy No. I.” Hollywood simply put the gangster in the Old West, which made the O.K. Corral story perfect for rival gangs to shoot it out. We’re at 35 movies about the Earps and counting, so I guess you could say Wyatt Earp’s story has legs.
