Straw Dogs is a 1971 psychological thriller directed by Sam Peckinpah and starring Dustin Hoffman and Susan George. The screenplay, by Peckinpah and David Zelag Goodman, is based upon Gordon M. Williams's 1969 novel, The Siege of Trencher's Farm. The film's title derives from a discussion in the Tao Te Ching that likens the ancient Chinese ceremonial straw dog to forms without substance.
