The international reach of Fringe still catches me by surprise a bit, at times. Also, I was given the gift of a character that is every actor's dream. So, you combine those two factors and it's been an incredibly memorable five years.

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 could go anywhere in the world and people would stop me in the street and talk about Fringe and how much they adored it and asked questions about it.

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.

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

Working in television is very hard. I think people know that.
