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.

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.

We often get pigeon-holed as a tough guy, or whatever else. I've been pigeon-holed as a heavy and serious, and almost a baddy, but not quite a baddy, over the years of my work in television, particularly.

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

We've had such a close relationship with the fans. Through social networking and the internet, we have much more contact, and we did go to things like Comic-Con. So, I think people know most of our secrets.

The international reach of Fringe still catches me by surprise a bit, at times. Also, I was given the gift of a character that is every actor's dream. So, you combine those two factors and it's been an incredibly memorable five years.

Doing animation is great fun. It's like a different world.
