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

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

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

You basically go in animation and it's all in the imagination. There aren't even pictures to look at. You usually go in there and work with whoever the director is to create this voice and this character.

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've played a bunch of different versions of Walter [from "Fringe"]... I loved it when he was being random, which was probably the original version of him, more than anyone else. I loved doing Walter then, and all of the different mental states that we've played.

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