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.

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.

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

I was thinking about that. I was thinking, this is like our Boyhood; this is like our getting together over 12 years to make - this our Apehood! I mean, this is it! For me, the relationships, all of those things, over such a long period of time now with actors, but also seeing the characters grow, develop, and change, and go through different situations.

I have a great interest in Victorian musical & cabaret performances and Weimar artists so the references are there, to Cabaret and also All That Jazz and other films where, where there's a kind of (influential German playwright Bertolt) Brecht-ian approach, almost to the character standing outside of himself or, in this case, he's "self-séance-ing."

You don't go - oh this is a motion capture role, I'm going to employ this method of acting. We don't have anything to hide behind when we're doing this.

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.
