Straw Dogs (1971 film) Territorial Imperative", which argued that man was essentially a carnivore who instinctively battled over control of territory. The film was shot on location at St Buryan, Cornwall. Beau Bridges, Stacy Keach, Sidney Poitier, Jack Nicholson, and Donald Sutherland were considered for the lead role of David Sumner before Dustin Hoffman was cast. Hoffman agreed to do the film because he was intrigued by the character, a pacifist unaware of his feelings and potential for violence that were the very same feelings he abhorred in society.
