Apocalypse Now
Martin Sheen's Captain Willard grows uneasy as Samuel L Jackson lurks menacingly in the swamp.
In order to stay focused during the long shoot, Jackson took to turning up to work naked - mindful also to avoid clothing-related jungle ailments such as nipple-chafe. Marlon Brando was so impressed by this dedication that he later copied the method, filming most of The Score (2001) in the nude.
