Former US Marine Corps Drill Instructor R. Lee Ermey was not originally hired to play Gunnery Sgt. Hartman but as a consultant for the Marine Corps boot camp portion of the film. He performed a demonstration on videotape in which he yelled obscene insults and abuse for 15 minutes without stopping, repeating himself or even flinching - despite being continuously pelted with tennis balls and oranges. Stanley Kubrick was so impressed that he cast Ermey as Gunnery Sgt. Hartmann.

R. Lee Emery was the only good thing about the Texas Chainsaw Massacre remake.
