'Fringe' is essentially a love story, so the scenes where Walter had close connection with Peter, but also with Anna's character or Jasika's character, were very special to me.

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.

We've had such a close relationship with the fans. Through social networking and the internet, we have much more contact, and we did go to things like Comic-Con. So, I think people know most of our secrets.

[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 suppose, when you start up in acting, you hope to be given challenges, and you always have dreams about the things you could do and couldn't do, but normally we get pigeon-holed a little bit, as we go on in our careers.

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.
