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

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 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.

Lord Of The Rings fandom was massive, worldwide, entrenched. Generally it had been part of the fans' life all their life, because they had it read to them as children; they'd become Tolkien students.

You're always working with the relationships. It's pretty demanding, but then again I love that.

I didn't drop into the mannerisms of another version of the character, but I guess I was pretty alert to that.

I'm a character actor, so as a character actor, I'm always looking for something interesting.
