Wyatt Earp's Revenge is a 2012 American Western film about the legendary lawman Wyatt Earp.
 It is a fictionalized account of an actual Old West event, the slaying of beautiful singer Dora Hand in Dodge City, Kansas, when Earp was a deputy there.
 In one of its many instances of dramatic license, the movie depicts Hand as Earp's sweetheart.
 The film's framing device is a reporter's interview with an aging Earp, who reminisces about the tragedy.
 (Val Kilmer plays the older Earp, while Shawn Roberts plays the younger one.)
 The film was released on March 6, 2012, in the United States.
 The film was produced by Jeff Schenck and Barry Barnholtz and directed by Michael Feifer.
 The screenplay was written by Darren Benjamin Shepherd.
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.
Glenn G. Boyer (January 5, 1924 - February 14, 2013) was a controversial author who published three books and a number of articles about Wyatt Earp and related figures in the American Old West.
 He was the first person to reveal the existence of Wyatt Earp's second wife, Mattie Blaylock.
 His publications were for many years regarded as the authoritative source on Wyatt Earp's life.
 However, when other experts began to seek evidence supporting Boyer's work, he would or could not prove the existence of documents that he said he owned and had cited as essential sources.
 In one case, an individual he cited as a key source was exposed as a complete fabrication.
 His reputation and the authenticity of his work was seriously damaged.
 Although he retained many supporters, his work became surrounded by controversy.
The 1976 book I Married Wyatt Earp was believed to be a memoir of his widow Josephine Earp, but was many years later described as a fraud, creative exercise, and a hoax.
 Originally published by the respected University of Arizona Press, it is the second best-selling book about western Deputy U.S. Marshal Wyatt Earp ever sold.
 It was regarded for many years as a factual account that shed considerable light on the life of Wyatt Earp and his brothers in Tombstone, Arizona Territory.
 It was cited in scholarly works, assigned as classroom work, and used as a source by filmmakers.
 Amateur Earp historian Glenn Boyer said that the retouched image on the cover of a scantily-clad woman was of Josephine in her 20s, and based on his statements, copies of the image were later sold at auction for up to $2,875.
Wyatt Berry Stapp Earp (March 19, 1848 – January 13, 1929) was an American Old West gambler, a deputy sheriff in Pima County, and deputy town marshal in Tombstone, Arizona Territory, who took part in the Gunfight at the O.K. Corral, during which lawmen killed three outlaw cowboys.
 He is often mistakenly regarded as the central figure in the shootout in Tombstone, although his brother Virgil was Tombstone city marshal and deputy U.S. marshal that day, and had far more experience as a sheriff, constable, marshal, and soldier in combat.
Jimmy Noel (May 15, 1903–January 31, 1985) was a Massachusetts-born actor and stuntman who appeared in hundreds of largely uncredited roles in film and television between 1949 and 1975.
 He appeared 202 times on CBS's western series, "Gunsmoke", starring James Arness, and in 144 episodes of the ABC/Desilu production, "The Life and Legend of Wyatt Earp", with Hugh O'Brian in the title role of deputy Marshal Wyatt Earp.
 Buddy Roosevelt made similar appearances in sixty-five "Wyatt Earp" episodes.
The O.K. Corral hearing and aftermath was the direct result of the 30-second Gunfight at the O.K. Corral in Tombstone, Arizona Territory on October 26, 1881.
 During that confrontation, Deputy U.S. Marshal and Tombstone Town Marshal Virgil Earp, Assistant Town Marshal Morgan Earp, and temporary deputy marshals Wyatt Earp and Doc Holliday shot and killed Billy Clanton, and Tom and Frank McLaury.
 Billy's brother Ike, who had repeatedly threatened to kill the Earps for some time, had been present at the gunfight but was unarmed and fled.
 He filed murder charges against the Earps and Doc Holliday on October 30.
Wyatt Earp: Frontier Marshal (1931) was a best-selling but largely fictional biography of Wyatt Earp written by Stuart N. Lake and published by Houghton Mifflin Company.
 It was the first biography of Earp, supposedly written with his contributions.
 It established the Gunfight at the O.K. Corral in the public consciousness and conveyed a mythic story about Wyatt Earp as a fearless lawman in the American Old West.
 Earp and his wife Josephine Earp tried to control the account, threatening legal action to persuade Lake to exclude Earp's second wife from the book.
 When the book was published, neither woman was mentioned.
Virgil Walter Earp (July 18, 1843 – October 19, 1905) was both deputy U.S. marshal and Tombstone, Arizona City Marshal when he led his brothers Morgan and Wyatt and Doc Holliday in a confrontation with outlaw Cowboys at the Gunfight at the O.K. Corral on October 26, 1881.
 They killed brothers Tom and Frank McLaury and Billy Clanton.
 All three Earp brothers had been the target of repeated death threats made by the Cowboys who were upset by the Earps' interference in their illegal activities.
 All four lawmen were charged with murder by Ike Clanton, who had run from the gunfight.
 During a month-long preliminary hearing, Judge Wells Spicer exonerated the men, concluding they had been performing their duty.
