The actor Kubrick first hired to play Gunnery Sergeant Hartman was Tim Colceri. Over the course of production, R. Lee Ermey, who was originally hired on as the technical advisor, found a way to ‘audition’ for the role despite it already being cast. Colceri would end up playing the door gunner who shoots at random civilians from the helicopter in the film, but the story of Colceri losing the role would certainly classify him as one of the most tortured Kubrick actors.
