I've done a fair amount of that stuff... when we did 'Lord of the Rings' the transformation sequence from Smeagol to Gollum was a 19-hour make-up job. You have to have a kind of zen button that you press and allow the mind to be focused in a certain way.

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'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.

Gorillas are still wild creatures. That's made very clear when you observe them in nature. They charge and perform other displays that are terrifying by design. But they don't attack unless they feel threatened.

For film and games, there is now a fantastic method of actors portraying characters which don't necessarily look like themselves. And yet you've still got the heart and soul of the performance.

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.

It's a really unique situation where you just - you make independent films or you make big blockbuster movies, but it's very rare when all of those ingredients come together, and you can really tell a story that you care about with a character you absolutely love with the people you love making movies with.
