Our free winter Sunday matinee documentary series from Sandbox Films continues with Nocturnes. In the dense forests of the Eastern Himalayas, moths are whispering something to us. In the dark of night, two curious observers shine a light on this secret universe. Together, they are on an expedition to decode these nocturnal creatures in a remote ecological “hot spot” on the border of India and Bhutan. The result is a deeply immersive film that transports audiences to a rarely seen place and urges us all to look more closely at the hidden interconnections of the natural world. Sandbox Films is an Oscar-nominated production studio that illuminates the art and beauty of scientific inquiry: humankind’s weird, messy, brilliant way of navigating the world. Free hot chocolate!
