the inspiration for our horror films
""
The Texas Chain Saw Massacre... What happened is true! Now the movie that's just as real!", screamed the posters for Tobe Hooper's 1974 classic of independent cinema. Whilst not a literal rendition of the Gein case, the terrible house in Chain Saw, with its bizarre artifacts made out of human detritus - armchairs that bear human arms, lamps made out of human hands - resembles the Gein homestead in many of its particulars, and the crazy Leatherface, who hangs up his victims alive on meat hooks, also sports a grotesque mask fashioned from stitched together pieces of human skin. In Joseph Ellison's 1980 study of psychopathic child-abuse "Don't Go In The House", Donny (Dan Grimaldi) keeps the corpse of his religious fanatic mother in his apartment, and, as a consequence of her nasty habit of burning his arms when he misbehaved as a child, enjoys nothing better than bringing a young woman home and frying her up alive. In William Lustig's "Maniac" (1980), the eponymous Oedipal killer indulges in garroting, deception, shooting and scalping, with the murderer's scalp collection adorning a row of tailor's mannequins.
Gein's fondness for wearing human flesh resurfaced again in 1991 as one inspirations for the character Buffalo Bill in Jonathan Demme's
"Silence of the Lambs", the homosexual psycho killer so named because he liked to "skin his humps". Gein was also the inspiration for the psycho-biopic "Deranged", a 1974 offering from American-International Pictures, co-written and co-directed by Alan Ormsby, and the lesser known but equally reverential "Three On A Meathook" (1973), directed by small-time auteur William Girdler and filmed in Louisville, Kentucky. It also seems likely that Jorg Buttgereit, a self-confessed "Geinophile", was influenced by Eddie's predilections whilst making his paeans to necrophilia, "Nekromantik" (1988) and "Nekromantik 2" (1991)."
