Acting is not about dressing up. Acting is about stripping bare. The whole essence of learning lines is to forget them so you can make them sound like you thought of them that instant.
If I stay alert, then I can challenge myself, and by challenging myself, that helps me to stay alive and to hopefully take something away from the experience.
I was so flattered to be asked to be in the movies - the idea of being paid to act was heady stuff.
