I have never had great expectations of my performance or of a film. I try not to think about the outcome. If you look that far ahead, it sort of taints your choices as an actor. I try as hard as I can to believe that no one is ever going to see it and that it's not even a movie. Then you can allow yourself to bare more. Then, once a project is done, I tend to forget about it until it comes out.
