As an actor, you want as much variety as you can muster up. Otherwise you just keep playing the same chord over and over again.

I did a show called 'Wonderland' a few years back, and I was fortunate enough to spend a full-on two weeks - I'm talking 13-15 hours a day - with the doctors and patients at Bellevue in New York. That served me well for 'Durham County.

At one point I had a stretch where it was working on 'In Treatment,' then 'True Blood,' then 'Durham County,' then 'True Blood,' then 'In Treatment' again. If I didn't have that little dose of 'True Blood' in the middle, I might have lost my mind.

I thought a vegan diet would be too difficult, being on the road so much, but it's been far easier than I thought.

I've never had a plan. You look for different actors you want to work with or different subjects you want to explore, or sometimes it's just a momentary fancy.

When I did 'Battlestar Galactica' it was the first time I really understood science fiction. That was a very political drama, but set in spaceships so people didn't really take it seriously. But some really fascinating things were explored in that.
