About this episode
Mike ventures deep beneath the surface with director Rob Petit to discuss Underland (2025), a haunting, meditative documentary that charts an extraordinary subterranean journey into the hidden worlds beneath our feet. Narrated by author and co-writer Robert Macfarlane, the film adapts his bestselling book Underland: A Deep Time Journey, bringing to life an awe-inspiring descent into caves, catacombs, glacial crevasses, and underground rivers spanning continents. More than just a travelogue, Underland explores humanity’s relationship with deep time—how we bury our dead, our nuclear waste, and our myths far below the surface. Mike and Petit explore the technical and philosophical challenges of filming underground, the role of sound and narration in shaping the film’s atmosphere, and how Underland uses darkness and silence to confront ecological crisis, mortality, and deep history. A lyrical, unsettling, and urgent cinematic experience, Underland burrows into the mind as much as the earth.
