The political nonsense of network television and the culture of a set and all the problems that that can create, I can take. I can't take betraying the truth of what I'm doing. It cuts to the absolute core of everything that I do in the craft, in this world that I live in.

If you go to the real West Wing in the White House it looks like a boring law office; there's really not a whole lot going on in series. The moulding is frayed, the carpet is a little dirty; it's not exciting.

I go in to Warner Brothers to test and in the waiting area I saw Allison Janney sitting there, who I did not know but I was a big fan of. I said to myself, "Wait a second. These guys might know what they're doing if they're hiring her."

I fell in love with my wife twenty years ago. I am only now, it seems, getting it through my very thick skull how lucky I am.

I turned down a lot of things - some very lucrative - because I could afford to at that time. That didn't lead to a happy place. I was happy to spend time with my family, get to know my daughter, who was born during The West Wing.

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.

Families are like puzzles. They fit together in a certain way, and if one piece is missing, it throws everything off.
