"Werner Herzog was the only filmmaker to have access to the world's oldest known paintings. Here these 32,000 year old drawings come to life. Lights flicker across the undulating, liquid-smooth walls of the Chauvet Cave. Herzog interviews various experts. Most fascinating of all, Herzog gives his own whispered take on the art and artists. The drawings of horses, bison, mammoths, rhinos, bears and lions often have multiple sets of legs, a blur 'like frames in an animated film'. Herzog speculates on the artists: 'Do they dream? Do they cry at night?' Herzog's poetic turn of phrase makes him the perfect tour guide. This is another lovely stanza in the epic poem of humanity that Herzog has been writing for half a century." - Roger Moore, Orlando Sentinel.
