This uninterrupted shot was filmed by the most advanced gyro-stabilized camera system, the GSS C520, mounted to a truck on a custom road built next to a custom trail that took three weeks to build. This true cinematic achievement required perfect coordination between Semenuk, Anthill Films, and TGR with regard to athleticism, planning, timing and logistics. Injured at the time, Semenuk only hit the full line once. The historic moment was produced for unReal, the feature mountain bike film inspired by the unprecedented creative union of production companies TGR and Anthill Films, and the limitless imaginations of a group of the best mountain bikers in the world.
