Corral, which had featured Burt Lancaster as Earp and Kirk Douglas as Holliday. However, Ike Clanton is killed at the end of the earlier film (during the gunfight at the O.K. Corral itself). In Hour of the Gun, Clanton not only survives the gunfight but is a major antagonist thereafter. Where Gunfight at the O.K. Corral is more about the main gun battle, this film begins with the gunfight and moves forward from there. Hal B. Wallis had scripted everything in the earlier Gunfight at the O.K. Corral, and Sturges was disappointed with that film. According to critic Paul Brenner, Hour of the Gun is more of a psychological "melancholy character study". The film's music is composed by Jerry Goldsmith. Garner wrote in his memoirs that he agreed to make the film without reading the script because he thought so highly of Sturges. Garner also played the lead as Wyatt Earp in a different film more than two decades later, Blake Edwards's Sunset (1988), a comedy thriller based on the 1920s period during which Earp was a technical adviser for silent films. In his second theatrical film, Bruce Willis portrays Tom Mix. Hour of the Gun was filmed in the state of Durango, Mexico; at Estudios Churubusco Azteca (studio) in Mexico City, México D.F., Mexico; San Miguel de Allende, Guanajuato, Mexico; and in Torreón, Coahuíla, Mexico. Reception At AllMovie, Bruce Eder calls Garner's portrayal of Earp as "taciturn, emotionally repressed, deeply troubled and torn" but criticizes Edward Anhalt's script as being too strict to historical facts and confining the actors, especially Garner. Roger Ebert from Chicago Sun-Times says: "Garner turns in one of his best performances."
