Cave of Forgotten Dreams is legendary director Werner Herzog’s documentary about the earliest known visions of mankind: the Chauvet-Pont-d’Arc cave art of southern France. Sealed shut by a landslide for 20,000 years until it was finally discovered in 1994, the Chauvet Cave in southern France contains some of the oldest known examples of prehistoric art. The film premiered at the 2010 Toronto International Film Festival and consists of footage filmed inside the cave as well as interviews with various scientists and historians.
