We didn't know until really quite late in the piece how Joel [Wyman] would finish it off.

I don't know how I absorb things, but I do. I just absorb them. I don't over read the script, and I don't really ever spend much time learning it.

I'm a character actor, so as a character actor, I'm always looking for something interesting.

I always loved the challenge. When something new happened, I always used to get quite excited.

I'm truly grateful to the writers of Fringe for giving me that because, over the years, when I've spoken about the character with them, I've always felt that this would be the perfect way to end and complete his journey, and to complete the journey of this series, and they gave it to me.

I didn't drop into the mannerisms of another version of the character, but I guess I was pretty alert to that.

I'd never done anything that required a five-year commitment. To build a show that seems to have kept the imagination of the world so much was a bit otherworldly.
