Cave of Forgotten Dreams

Cave of Forgotten Dreams is a 3D documentary by Werner Herzog that explores a remote cave in France known as the Chauvet Cave. This cave is home to many ancient human-made images, tens of thousands of years old. The cave is fiercely protected and generally inaccessible to the public, but Herzog was granted permission by the French Minister of Culture to film inside it, under strict restrictions designed to protect the cave and its contents.

The images painted on the cave walls represent long-forgotten dreams from an entirely different era of humanity. Capturing these images using 3D technology was initially a challenging concept for Herzog to come to grips with, as at the time of production, 3D filming technology was typically intended for use with constructed sets and digital manipulation. However, the location prevented the use of any kind of stage or heavy equipment. The documentary has won several Best Documentary awards and received an overwhelmingly positive reception.
