I was thinking about that. I was thinking, this is like our Boyhood; this is like our getting together over 12 years to make - this our Apehood! I mean, this is it! For me, the relationships, all of those things, over such a long period of time now with actors, but also seeing the characters grow, develop, and change, and go through different situations.

My first job when I got my equity card was acting in 14 plays back-to-back. Playing that many roles, you look for ways of differentiating the characters physically, which goes hand in hand with understanding them psychologically.

I'd already started directing short films when we were doing 'Lord of the Rings,' then videogame projects. So Peter's known that I've been heading towards directing for a long time. But I always thought my first outing would be a couple of people and a digital camera in the back streets of London somewhere!

I understand why people went nuts for 'The Artist.' We use words so much, it's nice to be able to explore a different way of communication, to be able to express silently what someone - or something - is thinking or feeling.

In the same way 'Lord of the Rings' was an interpretation of the book, 'The Hobbit' is being treated the same way. It will be faithfully represented with a fresh interpretation.

I remember kind of doing early acting and thinking, "God, they don't paint behind the sets." It's a bit of a shame, really - "Oh, what's on the other side of this wall? Oh, you can see the plywood." I was really disappointed. I just thought that these things were real, from watching things as a kid.

I remember once, I read in a horoscope, because I'm an Aries, I read this terrible thing, which really affected me, which said, "You will never be original. You will always be an interpreter." (Laughs) I thought, "Oh my God." You know, I had to live with that on my back for [all my life].
