I could go anywhere in the world and people would stop me in the street and talk about Fringe and how much they adored it and asked questions about it.

I remember when I read Walter, for example, six years ago now, I said, "This is the role for me." I said that to my family. There was something there that I knew was absolutely right, and that was just based on the character. That's when gut instinct comes into play. I know there are certain things I won't do.

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.

We often get pigeon-holed as a tough guy, or whatever else. I've been pigeon-holed as a heavy and serious, and almost a baddy, but not quite a baddy, over the years of my work in television, particularly.

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.

I'm truly grateful to the writers of Fringe for giving me that because, over the years, when I've spoken about the character with them, I've always felt that this would be the perfect way to end and complete his journey, and to complete the journey of this series, and they gave it to me.

'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.
