This was the first movie that depicted Wyatt Earp, and the only movie that included his character before he died in 1929. Earp's good friend William Hart produced and wrote the screen play with J.G. Hawks. Hart played Wild Bill Hickok and Bert Lindley played Earp. Earp's part in the movie was small. Lindley is not listed on some descriptions of the movie and this portrayal of Earp is often overlooked.
Promotional copy for the film prominently mentioned Earp: "Back in the days when the West was young and wild, 'Wild Bill' fought and loved and adventured with such famous frontiersmen as Bat Masterson and Wyatt Earp." Earp was described in the promotional copy as "deputy sheriff to Bat Masterson of Dodge City, known as one of the three greatest gun-men that ever lived, along with Bat Masterson and 'Wild Bill' Hickok."
