I think we all have a lot of darkness in our bellies. As an actor, the challenge of tapping into that, reaching down into that sadness or anger, is very therapeutic.

A good director creates an environment which gives the actor the encouragement to fly.

I would say invisibility would be sort of a fun power to have just to see what it was like to move through the world and not be looked at.

They took 3-D digital photographs of my entire body. I had to pose stark naked, assuming a kind of Spider-Man position. After a minute, one of the technicians pointed to my genitals and said, Um, we're not getting enough data there ... It wasn't what you think. It turns out that the fancy digital camera doesn't pick up dark areas too well, and they were having trouble because of the hair down there. I actually had to spray on this highlighter stuff.

I want to see the numbers that prove that show-business marriages are any less successful than other marriages. It's just very public when they fail.

I felt as if I was the brunt of some massive joke at my expense: Can you believe this loser can be connected to Marlon Brando and Katharine Hepburn? But through the years I have learned to tolerate and sometimes embrace the idea. People have asked me if I consider it an honour. Well, all it indicates is that I've been in a lot of movies with a lot of people. And besides that there are plenty of other actors that would work.

I'm very comfortable being married to an extremely strong, opinionated, and driven woman. But I also sit at the head of the table. I have both of those sides to me.
