You're working so hard and so many hours, you simply don't get to visit with everybody when you're gone for five months. That's part of the trade in we make with this career.

I had heard that Tom [Cruise] was the same way, that he is incredibly dedicated. I was very excited to meet him and I was, honest to God, weirdly surprised that the guy makes me look lazy.

I had just come off of doing a play in Los Angeles which actually got me the role. It was called Bent and it was at the Mark Taper Forum.
