We were looking at weather and our relationships with weather. It goes to a few other places, and I don't want to spoil anything, so I won't go into it, but it's about a willingness to expose oneself a little bit more and share something openly and honestly. It's more than just landing tricks. Moving forward, this is just another stepping stone.

We're all doing what we love. It's how we express ourselves - operating in a space where you don't know if something is possible or not.

Bryan [Iguchi] had this beautiful philosophy about our connection with these incredible cycles. There's a line from one of his poems that always stays with me about 'This process we follow; this cycle we ride' and it's almost become a strap line for the film.

Apart from those other riders there is a whole production team [ of The Fourth Phase] behind the cameras too, hauling hundreds of kilos of fragile and awkward filming equipment up those same frozen landscapes. They're the real heroes.

I've been to Japan so many times, but I still constantly stumble across things that are so foreign to me.

The whole goal with this thing [Ultra Natural] from the start was to really let rider's style define them and their line choice.

Ultimately it's a snowboarding film [Fourth Phase], of course, so the main thing that we wanted to celebrate was how awesome snowboarding is! Secondly, we wanted to celebrate the environment that we all shape our lives around. So the film documents myself and other like-minded individuals attempting to follow the hydrological cycles that shape the worlds we've committed our lives to.
