[Fringe] was just about doing the job, or trying to do the job, properly. It was never a job that you could rest on your laurels. It was a very challenging 43 minutes of television that we were shooting, every week.

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.

In Revelation 12, we see a pure, holy woman giving birth to a son - a corporate son who brings victory by the blood of Jesus, their testimony and sacrifice. My vision is to see that kind of church moving in the authority, the sacrifice and love of Jesus.

[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.

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.

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

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