Acting is reacting. No man thinks he is a fool. The more inventive you are, the better actor you are. There are no new stories. Avoid becoming a great thinker.
Adequate actors do their thing, even the triumph of no talent.
There are a lot of ass-holes out there who think acting is all about it being real. If a moment is important, take your time. Dream is another place, another person. Walk into it. I'm just in this dream.
