 There is a ripped poster of _Hills Have Eyes, The (1977)_ (qv)  visible. Ostensibly, this was in reference to a ripped poster for  Jaws that appeared in said film; Sam and the others interpreted that  as Wes Craven suggesting that Hills was much more frightening than  Jaws, thus they showed a ripped Hills poster because their film was  to be even scarier yet. See also:  _Hills Have Eyes Part II, The (1985)_ (qv),  _Nightmare On Elm Street, A (1984)_ (qv).
