I lost 30 pounds to play my character in 'The Mexican', but people don't take to skinny mafia men, and I don't feel right when I'm thin.
Humour is a great vehicle for getting a message across. If you get too serious, you could die of starch.
I think that people that are not sensitive, who seem to bang through life, do survive, but I don't think they get the really soaring feelings that people who are more artistically bent can get.
