Escape from Alcatraz is a 1979 American docudrama prison thriller film directed by Don Siegel. It is an adaptation of the 1963 non-fiction book of the same name by J. Campbell Bruce and dramatizes the 1962 prisoner escape from the maximum security prison on Alcatraz Island. The film stars Clint Eastwood, Jack Thibeau and Fred Ward as prisoners Frank Morris, Clarence Anglin and John Anglin. Allen West was played by Larry Hankin; his character's name was changed to Charley Butts. Patrick McGoohan portrays the suspicious, vindictive warden and Danny Glover appears in his film debut. Escape from Alcatraz marks the fifth and final collaboration between Siegel and Eastwood, following Coogan's Bluff (1968), Two Mules for Sister Sara (1970), The Beguiled (1971) and Dirty Harry (1971).
