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.

It seems not to matter that we are at the brink of a war that may spread beyond Afghanistan and Iraq to Iran and Georgia and then where? To Syria? To North Korea? To China? That we in America are in economic doldrums and are seeing small businesses fold and houses reclaimed by banks and a smouldering panic that is palpable everywhere.

One of the great things about the old days of television, 10 years ago, or 15 years ago, was that it was water cooler television. People would communally watch the same hour. People used to tell us all the time, we turn off the phones, we put the kids to bed and that one hour is uninterrupted. Then, the next day at the water cooler, they all talk about it.

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.

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.

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.
