Our feeling is that the most important thing on a set is that actors have enough confidence to try different things. If there's stress or tension, they won't go out on a limb because they won't want to embarrass themselves if they don't feel completely comfortable.
I find it hard to imagine how someone listens to my stuff, or views what I do, or me, or anything.
I just asked myself, what piece of that man's soul did he just chew off and swallow to get next week's assignment? You know, just to live, just to work as an artist, or to feed the family?
