 As with the Wes Craven movie _Hills Have Eyes, The (1977)_ (qv) this  movie is also based on the true story of Sawney Beane and his family  (a wife, eight sons and six daughters), a feral clan who inhabited  and roamed the highlands of Scotlands East Lothian County, near  Edinburgh, in the early 1400s. They were eventually captured on the  order of Scotlands King James, were judged to be insane, and  executed without trial.
