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.

[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 would kill to do more work with Orla Brady, I think she's that gifted.

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 always loved the challenge. When something new happened, I always used to get quite excited.

Mars tugs at the human imagination like no other planet. With a force mightier than gravity, it attracts the eye to the shimmering red presence in the clear night sky.

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