Over the last 25 years, since a lot of science writing became accessible to layman, I've become quite a consumer of science. As a child, I wasn't streamed into science, and I regret that now.

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 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.

You're always working with the relationships. It's pretty demanding, but then again I love that.

[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.

[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'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.
