I didn't drop into the mannerisms of another version of the character, but I guess I was pretty alert to that.

With science becoming far more accessible to all of us, I've become a pretty avid reader and devourer of it. One of the objectives that I had working with Fringe was to get more people talking about it because it's such fun.

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

I'm truly grateful to the writers of Fringe for giving me that because, over the years, when I've spoken about the character with them, I've always felt that this would be the perfect way to end and complete his journey, and to complete the journey of this series, and they gave it to me.

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

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

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.
