"How do you know you are an actor? Where does it begin, the desire to use yourself in this mysterious way? That fantasy was only one of many that helped me cope with a chaotic childhood. Is that kind of fantasy the beginning of an actor? Not for every child, certainly, but important it was to me and to my beginnings. For fantasy is what actors do—they pretend, they make believe, they imagine Lies Like Truth, as titled one of his books. The actor must find a way to make the fantasies given him by the playwright as connected, as important, as necessary to himself as mine were to my ten-year-old self."
