I imagine an America that can actually change. That we become a nation that prospers again but without pillaging the resources of nations that make their people hate us. That we become a nation that, as the constitution says in its preamble, its very first paragraph, 'promotes the general welfare' of its people.

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.

Most actors, unless they're big movie stars and can carve out huge chunks of time to focus on one movie that takes six months - the rest of us have to jump around to make ends meet.

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.

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.

My favourite British spots are any of the beautiful parks, especially on a sunny day such as this, after a long stretch of cold, cloudy and rainy days.

We are often too late with our brilliance. We are on time delay. The only instant gratification comes in the form of potato chips. The rest will find us by surprise somewhere down the road maybe as we sleep and dream of other things.
