Tim Colceri(I)

Was hired to play the Gunnery Sergeant/Drill Instructor in Full Metal Jacket (1987) after director Stanley Kubrick discarded his original idea of casting Bill McKinney in the role after seeing McKinney as the sodomy-minded hillbilly in Deliverance (1972). (Kubrick thought McKinney was too creepy.) He never got to play the role as Kubrick decided to use former D.I. R. Lee Ermey, who had been hired as a technical advisor, in the part. Colceri was bitter but accepted Kurbrick's consolation prize of a small role as the helicopter door-gunner.
