Produced for U.S. cable outlet TNT, You Know My Name is based on the colorful true story of Bill Tilghman, who went from Wild West lawman to Hollywood filmmaker to lawman again. Tilghman, played by Sam Elliott, was once an associate of Wyatt Earp and had run-ins with such famous outlaws as Cattle Annie and Little Britches. After retiring from law enforcement, Tilghman moved to California and began producing a series of silent Westerns that stressed historical authenticity over the grand-standing heroics of Tom Mix and William S. Hart. However, his films lacked name stars and failed to click at the box office. After his career in film went bust, Tilghman, nearly 70, answered a call from a friend to help him reform Cromwell, Oklahoma. Once called "the most sinful town in America," Cromwell was a place where vice was freely traded in many forms and the only peace officer was a violent, cocaine-addicted tyrant named Wiley (Arliss Howard).
