Paul Schofield said something like, 'If I'm not acting in a play, I don't really exist.' Those weren't the exact words, but he meant it's only when I'm acting in a play that I've got something to say about the world. And then why should I talk, when people can come to see it?
“I am an invisible man. I am a man of substance, of flesh and bone, fiber and liquids - and I might even be said to possess a mind. I am invisible, understand, simply because people refuse to see me.”
