Jack Nicholson on Acting (via Time magazine) ...

Time: Each of you has a scene of uncontrollable violent rage in this movie. Is rage easier or more fun to play than other emotions?

Nicholson: What kind of a question is this? You got to be able to play anything. Playing your own grandmother pissing on the ground should be no more difficult than carrying the groceries up the driveway before you get shot. That's acting. That's the real answer to the question.
