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

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

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

As actors, you don't actually need to know the future of the character. You just need to know the backgrounds.

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'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 was a theater man, so I was never in the situation of being a handsome Hollywood leading man, and then having to age.
