William Hornbeck was an American film editor and film industry executive. In a 1977 poll of film editors, he had been called "the best film editor the industry has produced."
He was nominated four times for the Academy Award for Best Film Editing, and won the award for A Place in the Sun (1951). Other important credits include It's a Wonderful Life (1946), Giant (1956), and I Want to Live! (1958). He edited films from notable directors including Zoltan Korda, Frank Capra, and George Stevens. Universal Pictures almost brought him on board to completely re-edit George Lucas' American Graffiti.
