Directed by John Sturges and starring Burt Lancaster and Kirk Douglas, Gunfight at the O.K. Corral dramatizes the alliance between lawman Wyatt Earp and gunslinger Doc Holliday as their conflict with the Clanton gang builds toward the legendary 1881 shootout in Tombstone. The film is based on George Scullin’s article The Killer and turns one of the Old West’s best-known historical confrontations into a large-scale classic Hollywood Western.
