In this 3D documentary, Werner Herzog takes a dive into the Chauvet Cave in Southern France. From archaeology and anthropology to master perfumery, scientists across disciplines have studied the cave with a palpable enthusiasm—making their best guesses about each cave drawing, based on the data that can be collected without destroying the site. It’s fascinating to hear how they hypothesize where they can find new entrances, or how prehistoric humans could have made music. Cave of Forgotten Dreams turns a regular documentary into a profound meditation about the human soul, creation, and human history. Herzog compiles clips of his interviews with the scientists alongside footage of the cave itself and his own narration, and mixes it with an ethereal score to turn this exploration into a religious epiphany.
