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

I have a very special love for all of those actors [in Fringe] and I'll miss them.Over the five years, we were given the chance to develop some pretty close bonds, both with our characters and personally, and we did.

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

[on playing Walter] 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. It was like everything you could possibly hope for, over five years. So, I was a very lucky actor.

I would kill to do more work with Orla Brady, I think she's that gifted.

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.
