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.

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.

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.

We've had such a close relationship with the fans. Through social networking and the internet, we have much more contact, and we did go to things like Comic-Con. So, I think people know most of our secrets.

It might be different for people that are A-list actors, but a lot of us really look at what's offered to us and look for something that has some traction with other people. But, it's not like I read 100 scripts a week, and then pick and choose. Maybe some actors do. I certainly don't do that.

My last two characters have been Denethor and Walter Bishop. Both will be hard acts to follow. That sits in the hands of my managers, at present. I just have no idea what's going to be offered to me.
