One of the fascinating pieces of trivia below is true*, the other is false. Do YOU know which is which?

Full Metal Jacket (1987)

1) According to director John Boorman, Stanley Kubrick wanted to cast Bill McKinney in the role of Gunnery Sgt. Hartman. However, Kubrick was so unsettled after viewing McKinney’s performance in Deliverance that he declined to meet with him, saying he was simply too frightened at the idea of being in McKinney’s presence. Kubrick then hired Tim Colceri to play Hartman. Colceri never got to play the role, as former US Marine Corps Drill Instructor R. Lee Ermey, consultant for the Marine Corps boot camp portion of the film, 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 Hartman. Colceri was bitter but accepted Kubrick’s consolation prize of a small role as a helicopter door-gunner.

2) To this day, actor Vincent D’Onofrio can’t go to sleep at night unless he’s savagely beaten by bald men with bars of soap wrapped inside towels. This fetish has cost him six marriages, but he’s been voted “Most Well-Rested Man in Hollywood” a record 11 times. He also can’t defecate on the toilet unless he puts a loaded rifle in his mouth first.
