I wanna be in action movies, I wanna be the tough guy I wanna scare people.

I would love to be in the position where the role is challenging enough that I need three months to prepare for it and then six months to live the life of character.

I didn't expect NBC would be at all thrilled about me, because the year before the West Wing I had rejected a pilot at the last minute and got them very upset. I ended up not coming to the casting - in fact it happened four different times because I just wasn't convinced that I wanted to do television.

I had been used to improvising and even in the audition I was feeling free to rearrange Aaron Sorkin words a little bit, as lovely as they were. I didn't find out until after I got the part how furious Aaron was at me for doing that. They said, "He was livid. He did everything in his power not to jump down your throat!" But I came to realise that Aaron was writing in metre and the rhythm of the language is very important.

You had actors that came from live theatre and it felt like you're doing a play. Every time we did a three or four minute walk-and-talk in the West Wing, the exhilaration of going on stage would be a part of it.

Every role is challenging in its own way, but the most challenging roles are the ones that are badly written - then it's completely up to you to come up with something that is interesting to the story and myself as an actor.

I love my wife but sometimes not so much. Frustration and fights can muck up a good thing. And just when a thing can move past differences and into the realm of peace and prosperity, another thing - an old idea or new interpretation or any spark that relights the paradigms that comfort us - will keep us where we are, where it is safe.
