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

I think main storylines are what always intrigued me, with those that were the relationships between the characters against whatever backdrop, whether it was in an ordinary universe or a universe in the future.

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.

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.

Many very strong fathers have turned out ineffectual sons by not allowing them to grow as men.

What I've observed is that television in the last decade has increased to something that's almost unrecognizable. They are feature films. That's a huge shift, and it's something the audience expects. They still may want to watch their half-hour sitcom, but when they watch scripted drama, they expect the standard.

I find science really sexy and, at the time that I was a school kid, it certainly wasn't.
