William Thomas Harris III (born September 22, 1940) is an American writer, best known for a series of suspense novels about his most famous character, Hannibal Lecter. The majority of his works have been made into films, the most notable being The Silence of the Lambs, which became only the third film in Academy Awards history to sweep the Oscars in major categories.
The Silence of the Lambs (1991) Review
I know since it won a bunch of Oscars people like to call it a thriller but one character eats people, and another skins them alive and wears their skin as an outfit. I am going to go with a horror film for this one.
