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.

I've always thought of acting as a tool to change society. I watch a lot of actors and I see panic in their eyes because they don't know why they act and I know why I act. Whether I'm a good or a bad actor, I know why I do it.

There is always that potential in the same way - Roddy McDowall ended up playing Cornelius to Caesar [in the Planet of the Apes]. Two different characters. That's the joy of the craft. Bring it on I say.

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.

Working from home is so, so hard because I want to be present for them and yet there's so much to do work-wise. That's the biggest challenge for me.

Gorilla tourism is vital to Rwanda's economy: It's the third highest source of income.

But I think there's something wonderful and extraordinary about climbing on your own and just that kind of relationship to the environment. I'm very addicted to the mountains. You know, so, I do like that solitude.
