The Philosophy of Horror is a seven-part abstract adaptation of Noël Carroll’s influential film theoretical book of the same title (published in 1990), which is a close examination of the horror genre. The film uses hand painted and decayed 35mm film strips of the classic slasher movie A Nightmare on Elm Street (Wes Craven, 1984) and its sequel A Nightmare on Elm Street 2: Freddy's Revenge (1985).
