My first job when I got my equity card was acting in 14 plays back-to-back. Playing that many roles, you look for ways of differentiating the characters physically, which goes hand in hand with understanding them psychologically.

Working with people you adore and love. There's just a sense, all the way through all of the movies [Planet of Apes], that you're very rarely in a position where you have great material that you're passionate about and a big audience who love it, and the detail and nuance, and the exquisiteness of the fantastic actors and director with great writing.

Acting is acting, as far as I'm concerned and, you know, how you manifest it is, at the end of the day, not the point. It's how it affects the story & how it affects the audience. And if people are hungry to be told stories, using, using this form then there's a reason for that.

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."

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!

On lower budget things you're still working collaboratively, but the investment and your level of creative importance is higher on something like 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.
