I'm working from home a lot. That's very unusual because I'm away a lot, sometimes working on the other side of the world for long periods of time. So, it's hard to manage in the sense that I want to be the best dad I can be but it's almost harder when you have your kids outside the door.

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

Rather than something like King Kong where I really went after studying gorillas in the wild and captivity. I based Caesar [ from the Rise of the Planet of the Apes] on a real chimpanzee and I worked with Terry [Notary] on a lot of chimpanzee movement.

It's really up to the acting community to be willing to be educated about what performance capture is in order to fully appreciate it as acting. It's not a type of acting, but rather the use of technology to harness an actor's performance and translate it into an ape, another animal, or an avatar of some kind.

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.

Performance capture is a tool that young actors will need in the next 10, 20 years. It's on the increase, as you say. It's not going away.

My belief about performance capture is that it's a technology which allows actors to play extraordinary characters. But from an acting perspective, I've never drawn a distinction between playing a conventional, live action character and playing a role in a performance capture suit. And from a purely acting point-of-view, I don't believe there should be a special Oscar category because I think it sort of muddies the waters in a way.
