Butch Cassidy and the Sundance Kid is a 1969 American Western film directed by George Roy Hill and written by William Goldman. Based loosely on fact, the film tells the story of Wild West outlaws Robert LeRoy Parker, known as Butch Cassidy (Paul Newman), and his partner Harry Longabaugh, the "Sundance Kid" (Robert Redford), who are on the run from a crack US posse after a string of train robberies. The pair and Sundance's lover, Etta Place (Katharine Ross), flee to Bolivia in search of a more successful criminal career. In 1979, Butch and Sundance: The Early Days, a prequel of sorts, was released starring Tom Berenger as Butch Cassidy and William Katt as the Sundance Kid. It was directed by Richard Lester and written by Allan Burns. William Goldman, the writer of the original film, was an executive producer. Jeff Corey was the only actor to appear in the original and the prequel.
