Walter is incredibly complex. I do a lot of thinking about the work I do, and try to get the rhythms of scenes.

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.

A lot of the times, roles are chosen for us.

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 find science really sexy and, at the time that I was a school kid, it certainly wasn't.

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.
