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.
 The movie was directed by John Sturges.
John Harris Behan (October 24, 1844 – June 7, 1912) was sheriff of Cochise County, Arizona Territory, during the gunfight at the O.K. Corral and was known for his opposition to the Earps.
 Behan was sheriff of Yavapai County from 1871 to 1873.
 He was married and had two children, but his wife divorced him, accusing him of consorting with prostitutes.
 He was elected to the Seventh Arizona Legislative Assembly, representing Yavapai County.
 In 1881, Wyatt Earp served for about five months as undersheriff of the eastern half of Pima County.
 When Wyatt resigned, Behan was appointed to fill his place, which included the mining boomtown Tombstone.
 When Cochise County was formed in February 1881, Behan was appointed as its first sheriff.
 Tombstone became the new county seat and Behan's headquarters.
 Sadie Marcus was his mistress, possibly as early as 1875 in Tip Top, Arizona, and certainly from 1880 until she found him in bed with another woman and kicked him out in mid-1881.
The Cochise County Sheriff's Office (CCSO), headquartered in Bisbee, Arizona, is a local law enforcement agency that serves Cochise County, Arizona.
 It provides general-service law enforcement to unincorporated areas of Cochise County, serving as the equivalent of the police for unincorporated areas of the county.
 It also operates the county jail system.
 The Cochise County Sheriff's Office (CCSO) is sometimes referred to as the Cochise County Sheriff's Department (CCSD).
Newman Haynes Clanton (c. 1816 - August 13, 1881), also known as "Old Man" Clanton, was a cattle rancher and father of four grown sons, one of whom was killed during the Gunfight at the O.K. Corral.
 Two of his sons were involved in multiple conflicts in Cochise County, Arizona Territory including stagecoach robbery and cattle rustling.
 His son Ike Clanton was identified by one witness as a participant in the murder of Morgan Earp.
 Billy Clanton and Ike were both present at the Gunfight at the O.K. Corral in which Billy was killed.
 "Old Man" Clanton was reportedly involved with stealing cattle from Mexican ranchers and re-selling them in the United States.
 Records indicate he participated in the Skeleton Canyon Massacre of Mexican smugglers.
 In retaliation, Mexican Rurales are reported to have ambushed and killed him and a crew of Cowboys in the Guadalupe Canyon Massacre.
John Peters Ringo (May 3, 1850 – July 13, 1882)—known as Johnny Ringo—was a known associate of the loosely federated group of outlaw Cochise County Cowboys in frontier Tombstone, Cochise County, Arizona Territory, United States.
 He was affiliated with Cochise County Sheriff Johnny Behan, Ike Clanton, and Frank Stilwell during 1881–1882.
The Gunfight at the O.K. Corral was a 30-second shootout between lawmen and members of a loosely organized group of outlaws called the Cowboys that took place at about 3:00 p.m. on Wednesday, October 26, 1881 in Tombstone, Arizona Territory.
 It is generally regarded as the most famous shootout in the history of the American Wild West.
 The gunfight was the result of a long-simmering feud, with Cowboys Billy Claiborne, Ike and Billy Clanton, and Tom and Frank McLaury on one side and town Marshal Virgil Earp, Special Policeman Morgan Earp, Special Policeman Wyatt Earp, and temporary policeman Doc Holliday on the other side.
 All three Earp brothers had been the target of repeated death threats made by the Cowboys, who objected to the Earps' interference in their illegal activities.
 Billy Clanton and both McLaury brothers were killed.
 Ike Clanton claimed that he was unarmed and ran from the fight, along with Billy Claiborne.
 Virgil, Morgan, and Doc Holliday were wounded, but Wyatt Earp was unharmed.
 The shootout has come to represent a period of the American Old West when the frontier was virtually an open range for outlaws, largely unopposed by law enforcement officers who were spread thin over vast territories.
William Harrison Clanton (1862 – October 26, 1881) was an outlaw Cowboy in Cochise County, Arizona Territory.
 He, along with his father Newman Clanton and brother Ike Clanton, worked a ranch near Tombstone and stole livestock from Mexico and later U.S. ranchers.
George Whitwell Parsons (August 26, 1850 - January 5, 1933) was a licensed attorney turned banker during the 19th century Old West.
 He is remembered due to his having kept a detailed daily diary of his life in the west, especially while he lived in Tombstone, Arizona Territory from 1879 to 1887.
 He described life in Tombstone in detail, including his interaction with individuals who became famous such as Wyatt Earp and Ike Clanton.
Tombstone is a historic city in Cochise County, Arizona, United States, founded in 1879 by prospector Ed Schieffelin in what was then Pima County, Arizona Territory.
 It became one of the last boomtowns in the American frontier.
 The town grew significantly into the mid-1880s as the local mines produced $40 to $85 million in silver bullion, the largest productive silver district in Arizona.
 Its population grew from 100 to around 14,000 in less than seven years.
 It is best known as the site of the Gunfight at the O.K. Corral and presently draws most of its revenue from tourism.
The Earp Vendetta Ride was a search by Deputy U.S. Marshal Wyatt Earp, leading a federal posse, for outlaw Cowboys they believed had ambushed and maimed Virgil Earp and killed Morgan Earp.
 The Earp brothers had been attacked in retaliation for the deaths of three Cowboys in the Gunfight at the O.K. Corral on October 26, 1881.
 From March 20 to April 15, 1882, the federal posse searched southeast Cochise County, Arizona Territory for suspects in both Virgil's and Morgan's attacks.
 Several suspects had been freed by the court, owing in some cases to legal technicalities and in others to the strength of alibis provided by Cowboy confederates.
 Up to this point, Wyatt had relied on the legal system to bring the Cowboys to justice.
 Now he felt he had to take matters into his own hands.
