This ambitious year-long project blends contemporary documentary filmmaking with ancient mythology, creating a unique cinematic experience unlike anything you'll find when you watch online or in theaters.

What Is Matter of Britain?

Matter of Britain stands out as an innovative ethnographic fantasy documentary that documents a remarkable community performance of the Holy Grail myth—the legendary quest undertaken by King Arthur's knights to heal their wasted land. What makes this film truly special is its scale and authenticity: filmed over 12 months from 2023 to 2024, the project brought together over 300 community participants who embodied questing knights, ethereal angelic choirs, guiding anchorites, and tempting devils across multiple locations throughout the Mayfield parish.

The documentary captures not just a performance, but a cultural moment—a modern community engaging with timeless mythology in their own landscape. With support from prestigious institutions including Arts Council England, the Lund Trust, High Weald AONB, East Sussex Arts Partnership, the University of Reading, and the Museum of English Rural Life, Matter of Britain represents a significant artistic and cultural endeavor.
