The foreign audiences are somewhat surprised and happy to find an American film that asks questions about American culture. There's a certain kind of cultural imperialism that we practice. Our films penetrate every market in the world. I have seen and have had people reflect to me, maybe not in so many words or specifically, but I get the subtext of it - they're somewhat charmed and surprised and happy to see an American film reflect on our culture. Because they see other cultures reflect on our culture but they don't see US culture reflecting on itself in quite the same way.

Essentially, no one can control what other people think of the final outcome. Once it's done, the audience will like it or not, they may even think I'm an idiot. They can also think I'm brilliant or whatever, I can't control that. What I can control is the joy in putting it together, the process of the work itself. I try and create an atmosphere where we're all enjoying the work. That's the only thing you can hold on to, the only true thing.

The first idea of Captain Fantastic was a pretty radically different one. The genesis had to do with parenting and questions about parenthood and fatherhood specifically. I have two kids and I was grappling with what my values were and what I wanted to pass to my children. So I was positing different kinds of parents and different ways of parenting. I played with various ideas - very permissive parenting, very restrictive parenting and then I came up with the character of Viggo Mortensen, and much of it was aspirational, some of it was autobiographical.

I think my ultimate directorial style is 'play.' In reference to theater, it's called a play - I believe in that noun, and the verb that goes with it.

Film is a pretty poor medium to deliver a message. I'm not trying to do that. I'm just trying to ask a lot of questions and hopefully you can draw your own conclusions about whatever meaning might be there or what point there is; but I was conscious of wanting to create something that for a lack of a better word had a positivity and earned that.

I think that we are all the heroes of our own story, and I think life comes in all shades of gray. Personally, I love movies that exist like this, where you think someone can behave both heroically and like a villain.
