“The whole thing was the hardest thing that I had ever done,” Bell admits. “But the hardest part of it was filming in the winter, in those -50 Fahrenheit conditions. Everything broke, you don’t get any battery life, your hands stick to tripods and metal. We figured out you could only really film for two to three hours a day, when the sun would come up over the mountains and it would warm up to a cozy minus-25." bye.
