Adapted from Robert Macfarlane's bestselling book, this mesmerizing documentary journeys into worlds seldom seen by human eyes. Beginning in the shallow soil beneath an ancient ash tree, we travel alongside three intrepid "astronauts of the underworld" into sacred ancient caves, flooded storm drains and deep underground laboratories designed to unravel the universe's mysteries. Narrated by Sandra Hüller with poetic sensitivity, the film presents a groundbreaking perspective on our relationship with the earth beneath our feet — a realm that most associate only with darkness and fear but that holds wonder and knowledge for those courageous enough to explore. Director Rob Petit crafts a sensory masterpiece that blends stunning visuals with a thoughtful exploration of our planet's hidden realms. The film's hypnotic imagery and contemplative tempo create an almost meditative viewing experience, allowing audiences to ponder captivating scenes from these subterranean worlds. Hüller's narration anchors the film's spectacular visuals in profound questions about humanity's place within — not merely atop — the earth. Produced by Darren Aronofsky, Underland offers a rare documentary experience that serves simultaneously as visual splendor, an environmental statement and a philosophical inquiry. This film challenges perceptions and expands understanding of our planet's hidden dimensions, delivering beauty, science and wonder in equal measure, resulting in a profound reevaluation of the ground beneath our feet.—Jarod Neece
