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

There's a certain pattern that exists with geniuses - an eccentricity, a lack of social graces and an inability to really communicate with mere mortals.

I love having played Walter because I suppose any actor brings a certain aspect of their own personality to their work, and I had a fairly broad canvas to paint on with the different versions.

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 loved playing Walternate because he was completely the same character, version 1985, and then it developed in such a different way, physically and mentally. So, to be able to play that, in the same television series, as playing the other ones was a fantastic gift for me.

I suppose, when you start up in acting, you hope to be given challenges, and you always have dreams about the things you could do and couldn't do, but normally we get pigeon-holed a little bit, as we go on in our careers.

I have a very special love for all of those actors [in Fringe] and I'll miss them.Over the five years, we were given the chance to develop some pretty close bonds, both with our characters and personally, and we did.
