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.

I could go anywhere in the world and people would stop me in the street and talk about Fringe and how much they adored it and asked questions about it.

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

Many very strong fathers have turned out ineffectual sons by not allowing them to grow as men.

[Fringe] was just about doing the job, or trying to do the job, properly. It was never a job that you could rest on your laurels. It was a very challenging 43 minutes of television that we were shooting, every week.

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.

It was wonderful to be able to play a character who had so many colors and who was able to play comedy, to play incredibly vulnerable, which he did a lot of the time, to play the love story, and to play the relationship with the son, which is quite unusual. That's a gift to me, as an actor.
