The wonderful thing about 48 fps is the integration of live action and CG elements; that is something I learned from 'The Hobbit.' We are so used to 24 fps and the romance of celluloid but at 48 fps, you cannot deny the existence of these CG creations in the same time frame and space and environment as the live action.

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.

I'm definitely moving more towards directing now.

Second films are, you know, like 'difficult second albums', so it's a tricky position to be in but I think he's made a highly accomplished film.

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!

The matter is - we are actors playing roles [in Planet Apes] and they happen to be in this instance apes but there's no difference. In the scenes that we're playing, if we were to block out the scenes as actors in costumes, it would be no different.

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.
