I remember the day Richard Nixon won in 1968. That was a time that seemed certain to bring about long awaited seismic change in America. But events of tragic proportion took us on a turn. Bobby Kennedy and Martin Luther King, Jr. were suddenly dead.

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.

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.

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.

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

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.
