My Darling Clementine is a 1946 American Western film directed by John Ford and starring Henry Fonda as Wyatt Earp during the period leading up to the gunfight at the O.K. Corral. The ensemble cast also features Victor Mature (as Doc Holliday), Linda Darnell, Walter Brennan, Tim Holt, Cathy Downs and Ward Bond. The title of the movie is borrowed from the theme song "Oh My Darling, Clementine", sung in parts over the opening and closing credits. The screenplay is based on the fictionalized biography Wyatt Earp: Frontier Marshal by Stuart Lake, as were two earlier movies, both named Frontier Marshal (released in 1934 and 1939, respectively). My Darling Clementine is regarded by many film critics as one of the best Westerns ever made. In 1991, the film was deemed "culturally, historically, or aesthetically significant" by the Library of Congress and selected for preservation in the United States National Film Registry; it was among the first 75 films entered into the registry. Plot In 1882 (a year after the actual gunfight at the O.K. Corral on October 26, 1881), Wyatt, Morgan, Virgil, and James Earp are driving cattle to California when they encounter Old Man Clanton and his sons. Clanton offers to buy their herd, but they curtly refuse to sell. When the Earps learn about the nearby boom town of Tombstone, the older brothers ride in, leaving the youngest, James, as watchman. The threesome soon learns that Tombstone is a lawless town without a marshal. Wyatt proves the only man in the town willing to face a drunken Indian shooting at the townspeople. When the brothers return to their camp, they find their cattle rustled and James murdered. Wyatt returns to Tombstone. Seeking to avenge James's murder, he takes the open position of town marshal and encounters the hot-tempered Doc Holliday and scurrilous Clanton gang several times. During this time, Clementine Carter, Doc's former love interest from his hometown of Boston, arrives after a long search for her beau. She is given a room at the same hotel where both Wyatt and Doc Holliday reside. Chihuahua, a hot-tempered Latina love interest of Doc's, sings in the local saloon. She runs afoul of Wyatt trying to tip a professional gambler off to his poker hand, resulting in Wyatt dunking her in a horse trough. Doc, who is suffering badly from tuberculosis and fled from Clementine previously, is unhappy with her
