Isn't it funny? You hear a phone ring and it could be anybody. But, a ringing phone has to be answered doesn't it?

I didn't grow up with my dad, so it was always very funny to me, and always has been, what an important part DNA plays in one's life.

When we shoot 24, there are so many things I have to worry about, from the script to technical things to my performance, that I dont have a second to be bored or take anything for granted. We produce 24 hours of film a season, which is like making 12 movies.

When I wasn't the flavor of the week or month or day, those were hard times.

My focus on 9/11 was on the victims - in the towers, in the planes - and all that loss.

I do believe very strongly that all of us and all of the other things in the context of our planet with Mother Nature, all of these things absolutely have a profound effect.

I had an unbelievable experience on '24'. We shot 198 episodes, and I was as excited about shooting the 198th as I was the first.
