The learning curve is 'The Hobbit' is being shot in 3D.

And 'Sex Drugs Rock Roll' was a very transitional film for me in that I was one of the producers and you know, came up with the idea with the writer and the producer, as well. But, it was a very collaborative event. You know, I really love working in that way.

I'm in the early stages of a film called 'Freezing Time' about Eadweard Muybridge, the Victorian photographer who was really the forefather of cinema. Digital animators still treat his images like the Bible. He was a very obsessed man.

It's a different rhythm than most movies. For a lot of the actors, you're 12,000 miles away from home. It becomes a way of life - getting up at five in the morning, shooting every day, day in day out, for 270 days. The new cast playing the dwarves were carrying incredibly heavy weights in their suits, they sat through hours of make-up every day. So it's quite challenging from a stamina point of view.

You don't go - oh this is a motion capture role, I'm going to employ this method of acting. We don't have anything to hide behind when we're doing this.

I never felt totally, 100%, patriotically English... I'd seen a lot of the world by an early age - sort of spent a lot of time traveling around Lebanon and I'd seen Babylon, and Damascus, and all sorts of places in the Middle East by the time I was ten. Then we'd return to Ruslip in West London... Done a fair bit of traveling really.

I love, first of all, reading and discovering what the common perception is and then trying to figure out... well, how does your life cross over into that character, or what's an angle on this that might challenge the status quo? It's just a great journey as well as an education. You're constantly being educated - it's like I'm back at school and making up for lost time.
