 A story circulated for a long time that Dustin Hoffman (qv) (being  a "method actor") stayed up all night to play a character who has  stayed up all night. Arriving on the set, Laurence Olivier (qv)  asked him why he looked the way he did. Hoffman told him, to which  Olivier replied in jest, "Why not try acting? Its much easier."  Dustin Hoffman repeatedly denied the story, and finally cleared up  the story in 2004. The torture scene was filmed early in the  morning, Hoffman was going through a divorce from his first wife and  was depressed, and had spend the previous two nights partying hard.  Hoffman told Olivier this and his comment related to his lifestyle  and not his "method" style of acting.
