One Big Eye is a hand-processed 16mm film shot at Pando, an ancient aspen grove that extends across 106 acres in south-central Utah. Seemingly 47,000 individual trees, it is unified by a single, interconnected root system, making it a ‘forest of one.’ Believed to be between 16,000 and 80,000 years old, it is the largest and heaviest known organism on land. Pando’s invisible root system is a guiding metaphor that emphasizes the interconnectedness between humans and non-human beings, as well as the notion of oneness described by many spiritual traditions. The footage was processed at home in the kitchen with an eco-friendly, coffee-based developer that leaves unpredictable inscriptions and traces on the film surface, at times creating visually abstract and speckled images. The filmmakers see this materially focused film practice as a form of devotion, and an opportunity to rethink ecological entanglements.
