Cave of Forgotten Dreams (2010) is a surreal documentary by Werner Hertzog offering viewers an unprecedented glimpse of Europe’s oldest Palaeolithic art inside France’s Chauvet Cave. As we step into the cave, we cross a threshold between present and past, waking and dreaming, fact and truth... sanity and insanity... A place where juggling archaeologists dream of lions, perfumers find caves by smell, and nuclear crocodiles draw closer every year.
