I love having played Walter because I suppose any actor brings a certain aspect of their own personality to their work, and I had a fairly broad canvas to paint on with the different versions.

Particularly in the final season [of Fringe], when we were shooting seven-day episodes with a reduced budget and big special effects, the team was so polished, by then, that we were able to do it and, I think, with incredible results.

I think main storylines are what always intrigued me, with those that were the relationships between the characters against whatever backdrop, whether it was in an ordinary universe or a universe in the future.

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

My last two characters have been Denethor and Walter Bishop. Both will be hard acts to follow. That sits in the hands of my managers, at present. I just have no idea what's going to be offered to me.

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.

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.
