There are no rhymes or reason, actually. Having said that, you know, cause there are people who are absolutely single-minded about their process and they can still come up with great work. But (what) I enjoy and it's the same, I suppose, as I became more of a family man, I enjoy, I enjoy an atmosphere where it, you know, doesn't have to be about conflict to get good results.

I just directed The Jungle Book with Cate Blanchet and Christian Bale.

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.

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.

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.

My agent told me they were casting for the voice of Gollum. I hadnt read The Lord of the Rings, but I read the script and realized what an amazing role it was. I developed a voice for the audition tape, then met Peter Jackson and Fran Walsh at the auditions and fell in love with them both.

That's why I ended up going to Lancaster University, because they had a visual arts course, and in the first year it was like a broad visual arts course in sculpture, painting, graphics - all of that.
