Deranged (1974)
Deranged is a Canadian-American horror film made in 1974 and directed by Alan Ormsby and Jeff Gillen. It is also known by the title Deranged: The Confessions of a Necrophile in the USA. It is a low-budget movie that has since become something of a cult film and is based on the life of Ed Gein. The title is, however, misleading since Ed Gein never experimented with necrophilia; although a necrophile is also defined as "an obsessive fascination with death and corpses."
