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 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.

When you have children, you realize that at the end it's all about passing on, about handing down. The process of letting go, not attachment, but appreciating the beauty and value in the change, the transformation.

My dad was working abroad, in Iraq, and he was a doctor. We used to go and visit him, in Baghdad, off and on. For the first ten years of my life, we used to go backwards and forwards to Baghdad, so that was quite amazing. I spent a lot of time traveling around the Middle East.

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.

I don't see a difference between playing a performance capture role and a live action role, they're just characters to me at the end of the day and I'm an actor who wants to explore those characters in fantastically written scripts. The only caveat is a good story is a good character.

The difference between the big budget films I've done is the length of time. But in terms of the day-to-day, you're still going on to set, you're getting into character, and you're going and doing your job, so there's absolutely no difference. It's just the structure around it and the length of time. But in terms of budget and money, it doesn't really manifest itself.
