In 1974, the classic thriller by Tobe Hooper, The Texas Chainsaw Massacre, has many Geinian touches, although there is no character that is an exact Eddie Gein model. This movie helped put "Ghastly Gein" back in the spotlight in the mid-1970's.

Years later, Eddie provided inspiration for the character of another serial killer, Buffalo Bill in The Silence of the Lambs. Like Eddie, Buffalo Bill treasured women's skin and wore it like clothing in some insane transvestite ritual.

I'm not sure about the movie Psycho and its ties with Eddie Gein but there are some major similarities.
