In Wes Craven’s 1977 film “The Hills Have Eyes”, there is a scene where a poster for Jaws is seen on a wall. Ostensibly, this was to state that Hills was an even scarier film than Jaws.
Sam Raimi’s 1981 film “The Evil Dead” homages this reference by placing a “Hills Have Eyes” poster in the basement of the cabin.
Craven caught wind of this and in A Nightmare on Elm Street (1984) upped the ante by displaying both a torn poster for “The Evil Dead” and having the character of Nancy watch “The Evil Dead” in order to try and stay awake.
Never one to rest on his laurels, Raimi went back on the attack and in 1987’s “Evil Dead II”, Freddy Krueger’s razor tipped glove can be seen hanging above the door to the toolshed where Ash chainsaws his girlfriend’s viced head.
Consequently, every single one of Sam Raimi’s films contains a yellow 1973 Oldsmobile Delta 88 known affectionately as “The Classic”. (Supposedly this is the vehicle that Raimi lost his virginity in.)
This vehicle even appeared in “The Quick and the Dead”, a western film, though this time it was ensconced in a covered wagon frame.
