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

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

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.

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 find science really sexy and, at the time that I was a school kid, it certainly wasn't.

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.
