Rob Petit

Oscar-nominee Sandra Hüller narrates this cinematic adaptation of Robert Macfarlane’s bestselling book, UNDERLAND. The documentary voyages into worlds rarely glimpsed by human eyes to explore the world beneath our feet. One not of fear and darkness, but rather of knowledge and wonder that can be found nowhere else. Beginning in the shallow soils beneath an old ash tree, we travel alongside several ‘astronauts of the underworld’ into ancient sacred caves, flooded storm drains, melting glaciers, underwater burial chambers and a deep underground laboratory built to solve the mysteries of the Universe. UNDERLAND dives deep into the Earth to present a groundbreaking vision for rethinking our lives on this fragile surface.

Reviews

“The photography is spectacular. Petit and his crew have abseiled, crawled and waded through the darkness to chart the earth’s shadowy recesses.”

Philip De Semlyen

Time Out

“Despite its scant 79-minute runtime, Robert Petit’s thrilling, unnerving documentary Underland plays like a sprawling epic about the scope of human existence.”
