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.

I think being a good parent means that every day is a different challenge. It's about mindfulness and trying to be present. I think life goes really quickly and it's very easy to be tuned out, and not be present. That is what I've learned in my parenting experience, and I continue to be mindful of it.

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.

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.

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.

A lot of directors on a base level are fearful of actors and maybe even distrustful. I love the craft of acting and I love actors so I think they can probably sense that. They also know that I understand what their process is, having done it myself. The thing I come back to over and over again is that for most people who are not analyzing it from a critical point of view, most iconic film moments are actor moments. We show up to commune with another human being and their experience. We don't show up necessarily to watch a really cool dolly shot.
