Duelo de Titanes (Gunfight at the O.K. Corral)

After a long career as a lawman that made him a legend, Wyatt Earp (Burt Lancaster) decides to quit and join his brothers in Tombstone, Arizona. There, he would see them in a feud with the Clantons, a local clan of thugs and cattle thieves. When the showdown becomes inevitable, the help will come from Doc Holliday (Kirk Douglas), a terminally-ill gambler who happens to be another Wild West legend.
