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

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.

I have a very special love for all of those actors [in Fringe] and I'll miss them.Over the five years, we were given the chance to develop some pretty close bonds, both with our characters and personally, and we did.

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.

I've played a bunch of different versions of Walter [from "Fringe"]... I loved it when he was being random, which was probably the original version of him, more than anyone else. I loved doing Walter then, and all of the different mental states that we've played.

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.
