'Try acting, dear boy'

Inthe film Giant, James Dean try to create the edgy Jett Rink by keeping his bladder full for a scene with Elizabeth Taylor.

Then after blowing his lines, when trying to deal with his awe of Elizabeth Taylor, he decided to empty by his bladder in full sight of her, the crew and several thousand movie-struck onlookers.

Which brings Laurence Olivier’s comment to Dustin Hoffman, who had stayed up several nights to play a scene in which his character had stayed up several nights: "Try acting, dear boy."
