The first of several "official" versions of Stuart Lake's biography of Wyatt Earp, Frontier Marshall stars George O'Brien as the legendary lawman, here rechristened "Michael Wyatt" for legal reasons. Riding into a lawless frontier town, Wyatt immediately butts head with the crooked town boss (Alan Edwards). Tensions methodically mount to the inevitable shootout -- not at the OK Corral, but at the local saloon, where the obligatory golden-hearted dance-hall hostess (Irene Bentley) takes a bullet intended for our hero. George O'Brien's last starring western for Fox Studios, Frontier Marshall was remade under the same title by Allan Dwan in 1939, then by John Ford as My Darling Clementine in 1946. Incidentally, supporting player Ward Bond was featured in all three films in three different roles!
