From executive producer Werner Herzog (Cave of Forgotten Dreams; Grizzly Man) and director Ian Cheney (King Corn), The Arc of Oblivion is an unexpectedly playful search for an answer to a deeply existential question. Set against the backdrop of the filmmaker’s quixotic quest to build an ark in a field in Maine, the film heads far afield—to salt mines in the Alps, fjords in the Arctic, and ancient libraries in the Sahara—to illuminate the strange world of archives, record-keeping, and memory.
