Yeah, I mean, climbing's always been a massive hobby of mine up until, kind of, recent times when I've had family, but no, it's been a driving passion in my life and, uh, I've always wanted to climb the Matterhorn. It was the mountain that, sort of, inspired me to climb, as a youngster. So, it was great to be able to get to do it.

At the moment, my trajectory isn't to think about acting. I'm absolutely devoted to The Imaginarium, our projects and directing. And watching and enabling other actors do their thing in our studio is hugely rewarding. I expect at some point I'll probably want to go back on stage and do some theater, because I've not done theater in 10 years.

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

Motion capture is exactly what it says: it's physical moves, whereas performance capture is the entire performance - including your facial performance. If you're doing, say, martial arts for a video game, that is motion capture. This is basically another way of recording an actor's performance: audio, facial and physical.

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.

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.

I am a bit evangelical, I know, but performance-capture is still misunderstood.
