Anthill Films: The trails of the Whistler Bike Park have seen their fair share of screen time over the years, from segments in our past films to your next-door-neighbour’s POV edit. So, when it came time to filming the bike park segment for unReal, we knew we had to do something different. Many people have asked us how we made this segment: Was the dirt real? Did we use a green screen? Does this actually happen in Whistler? Well, in the final episode of Mind the Gap, we reveal how the Dirt Blizzard segment came to life.
