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.

I don't know where the line is. I don't know how much of myself is in Walter. There's got to be a bit of him there.

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.

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

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

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.

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.
