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.

I love to snowboard with no cameras: 100 percent.

It was just on a whole other level, getting to experience and ride that terrain. We spent a fair amount of time in the Hakuba Valley.

We will never know our full potential unless we push ourselves to find it. It's this self discovery that inevitably takes us to the wildest places on earth.

While researching the project [The Fourth Phase] I stumbled across this amazing research by a scientist called Dr Gerard Pollack who had done studies on what he called a 'fourth phase' of water.

I knew Shin [Biyajima] a little bit early on, but it's funny because where I really met Shin, and where he made a strong impression on me, was in Jackson Hole. I sledded back to a secret zone way deep in the Jackson backcountry to some freeriding. I got out there and followed some snowmobile tracks figuring it's just some snowmobilers.

They were all just chapters in the book, stepping stones. Each was perfect for where we were at the time, and I'm proud of them all. We couldn't have done this film [The Fourth Phase] without the other films pre-dating it and being part of the process.
