The infamous Ed Gein (1906-1984), aka the Butcher of Plainfield, certainly had an impact on horror cinema. He was the inspiration for Norman Bates in “Psycho” (1960) and influenced Tobe Hooper’s masterpiece “The Texas Chain Saw Massacre” (1974).
His own story is most accurately depicted in 1974’s “Deranged”. Not only is “Deranged” the most accurate adaptation of Gein’s doings but also a film that presents a sick and dangerous individual who went unnoticed for some time in a manner that feels very authentic and unglamourised. And while doing so it also infuses the morbid story with some very dark and wildly funny humour and that’s no small feat.
