A lot of the times, roles are chosen for us.

Walter is incredibly complex. I do a lot of thinking about the work I do, and try to get the rhythms of scenes.

Working in television is very hard. I think people know that.

Human beings, we have dark sides; we have dark issues in our lives. To progress anywhere in life, you have to face your demons.

I remember when I read Walter, for example, six years ago now, I said, "This is the role for me." I said that to my family. There was something there that I knew was absolutely right, and that was just based on the character. That's when gut instinct comes into play. I know there are certain things I won't do.

As actors, you don't actually need to know the future of the character. You just need to know the backgrounds.

My last two characters have been Denethor and Walter Bishop. Both will be hard acts to follow. That sits in the hands of my managers, at present. I just have no idea what's going to be offered to me.
