John Sturges directed this sequel to his Gunfight at the O.K. Corral, which is more of a melancholy character study than an action Western. The Edward Anhalt screenplay (based on Douglas D. Martin's Tombstone's Epitaph) traces Wyatt Earp's (James Garner) moral decline from a lawman with high ideals to a mean-spirited vigilante bent on personal revenge. Ironically, Doc Holliday (Jason Robards), an admitted lawless gambler, reacts to Earp's vengeful turnabout by becoming the moral force that Earp has rejected. When Earp's brothers are killed by goons employed by Ike Clanton (Robert Ryan), Earp becomes obsessed with vengeance and organizes a posse to track down the killers. ~ Paul Brenner, Rovi
