I love acting and certainly won't give it up, but it's part of a bigger canvas for me now.

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.

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.

Basically we're puppeteers and if you're there and you're in the character, the puppet is going to look good. It's going to breath life and I think once they find out how to trust this system, you just forget about it and just perform, then it's just second nature, it just becomes easy.

A lot of actors on film sets... very often they're not paying attention to the physical world around them. I think through studying art, I've always had that awareness and that's something that I've wanted to bring in to go beyond acting... As a form of expression, they are intrinsically linked.

Acting is a sort of pressure cooker that allows the fizz to come out the top. God knows what I'd be like if I didn't have that.

I love playing real characters... if they're not around anymore it's helpful because you won't get sued! But there's so much research involved and I love that part of the process.
