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 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.

[Fringe] was just about doing the job, or trying to do the job, properly. It was never a job that you could rest on your laurels. It was a very challenging 43 minutes of television that we were shooting, every week.

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.

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

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.

I'd never done anything that required a five-year commitment. To build a show that seems to have kept the imagination of the world so much was a bit otherworldly.
