A psychological thriller, Straw Dogs (1971) was directed by Sam Peckinpah from a script he co-wrote alongside David Zelag Goodman. They adapted the story from a 1969 novel titled The Siege of Trencher’s Farm, which was, in turn, written by Gordon M. Williams. Both cover the same plot, albeit with some exceptions here and there. For instance, there are different names for their respective lead characters.
