I think there will always be a particular generation of actors who think that they're going to be replaced by robots. But certainly the emerging actors understand that that's part of the craft.

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

Animators do amazing working translating and interpolating the characters [in the Planet of the apes], the facial performances. What we're creating on set - if you don't get it on the day, in the moment, on set, in front of the camera, with the director and the actors. The emotional content of the scene and the acting choices.

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 take is that acting is acting. A performance is a performance. With performance capture, if you don't get the performance on the day, you can't enhance the performance.

When you start to do research into gorillas or any kind of apes, if you're going to play them, that's one of the biggest misconceptions. And when I did Kong, you're not doing gorilla movements, you're not doing ape movements, you're looking for a personality. It's like saying okay I'm going to do human movements.

When I first was offered the role on Rise [of the Planet of the Apes], I always played Caesar as a human being within ape skin.
