Working in television is very hard. I think people know that.

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

With science becoming far more accessible to all of us, I've become a pretty avid reader and devourer of it. One of the objectives that I had working with Fringe was to get more people talking about it because it's such fun.

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

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

I loved playing Walternate because he was completely the same character, version 1985, and then it developed in such a different way, physically and mentally. So, to be able to play that, in the same television series, as playing the other ones was a fantastic gift for me.

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