We shouldn't be put out to pasture just because we've reached somebody's idea of retirement, which was certainly happening in Australia, and I think elsewhere as well.

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

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

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.

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.

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

A lot of the times, roles are chosen for us.
