If you had been a public figure from the time you were a toddler, if you'd had to fight for a life that felt real and honest and normal against all odds, than maybe to you might value privacy above all else. I have given everything up there from the time that I was three-years old. That's reality show enough, don't you think?

How could you ask me to believe in God when there's absolutely no evidence that I can see?

What the digital age has offered us, in terms of connectivity and transparency, is that all of these people from weird places in the world are all talking to each other, at four in the morning, and are sharing ideas. There's more openness than has ever been known, so that's a good thing.

I think I missed all of the wonderful things ... I missed the control that you have in film, and I missed getting it right, really getting it right, the way you hope people will see it. All of the things that people love about theater - the fact that it changes every night and that it's so spontaneous - all of those things just frighten me.
