Hour of the Gun is a 1967 Western film depicting Wyatt Earp and Doc Holliday during their 1881 battles against Ike Clanton and his brothers in the Gunfight at the O.K.

Corral, and the gunfight's aftermath in and around Tombstone, Arizona, starring James Garner as Earp, Jason Robards as Holliday, and Robert Ryan as Clanton.

Corral (1957) starring Burt Lancaster and Kirk Douglas, but in Hour of the Gun he strove for more historical accuracy than in most previous screen depictions of Earp's adventures.

In addition, Hour of the Gun portrays Doc Holliday as a graying Civil War veteran much older than the Earp brothers, though in fact he was younger than most of them and was too young to have served in that conflict.

The death of Curly Bill Brocious is inaccurately portrayed as a street shootout between Brocius and two others vs. Wyatt Earp and Doc Holliday.

Outnumbered but determined, Deputy Marshal of Tombstone Wyatt Earp, his older brother Virgil, who is the current City Marshal, his younger brother Morgan, a Tombstone special police officer, and ally Doc Holliday, who was made an officer and given a badge for the occasion, confront and get the best of the Ike Clanton gang in a violent shootout at the O.K.

When they are cleared, Virgil runs for re-election as Tombstone City Marshal but is ambushed and maimed by some of Clanton's hired guns.

While seeing Virgil and his family off to California for their safety, Earp kills Frank Stillwell, foiling an attempted ambush orchestrated by Clanton.

To entice Earp to remain in Tombstone, the city's leading citizens tell him they are seeking an appointment for him as Chief U.S.

Earp declines to give his answer to the offer immediately but tells Holliday that he is going back to Tombstone to accept the job.

Holliday glances at the countryside as his friend rides away and then resumes his poker game with his sanitarium health aide.
