About Robert Parrish
Robert Reese Parrish was an American film editor, director, and former child actor. He won an Academy Award for Best Film Editing for his work on Body and Soul (1947). As a young actor, Parrish was encouraged by John Ford to work behind the scenes, and first gained experience as an editing apprentice on The Informer. Parrish discovered that a "montage approach" was much more effective, with arbitrary cuts made a set time before and after each important action.
