I've always been very shy and sheltered; I think it was a good way of starting to communicate with people. I was taught as a child never to talk about myself, never to talk about my emotions. Of course, now I talk about myself constantly. Now I have to take reverse est.

Once I put that wig on, I didn't say an intelligent thing for four months. My voice went up. I walked differently. I'd ask incredibly stupid questions.

I guess it's a pretty common experience while making a movie. You have to let go of the result and just hang on to the experience and the process, where each role takes you to a different country, as it were: You're shipwrecked on this new island, you have no clothes, you have to figure out how you're going to live in this new character.
