Surviving the grind of 18-hour days and getting up at four in the morning to work out for an hour so I'd have the energy to do it again the next day. I did not know I had that discipline. I did not know I had the discipline to learn a seven-page scene in three hours to shoot that day or the next day. I didn't know that I was capable of realizing that potential.

I've been very lucky not to have turned down too many roles that I've later regretted.

I was happy to spend time with my family, get to know my daughter, who was born during The West Wing. I missed her first words. I missed her first steps. I'd leave work before she woke up and got home after she was asleep and didn't really know her. So it was important for that reason to reintroduce myself to the family after all of that hard work.

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.

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.

I love David Fincher - even though it was just two scenes, I loved the way we worked and could tell by the way he was shooting it that this was going to be an affective movie to say the least.

It was tough doing 'Underneath the Lintel' in New Jersey in the wintertime, but rewarding. Those audiences were lively and interactive. On-stage was great, but off-stage was difficult.
