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.

I don't know where the line is. I don't know how much of myself is in Walter. There's got to be a bit of him there.

We didn't know until really quite late in the piece how Joel [Wyman] would finish it off.

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.

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.
