In Cave of Forgotten Dreams, you follow Werner Herzog and his 3-D camera into one of the rarest and least accessible spots on earth — Chauvet Cave in Southern France.  Here, on its bumpy walls, approximately 32,000 years ago our human forbears painted hundreds of astonishingly lifelike wild animals — horses, cattle, reindeer, rhinoceri, lions, panthers, bears, antelopes — 13 or more species.  What a lot of game — and predators — there were  back then!  These are among the earliest paintings ever found.  Many are overlaid by the rougly parallel scratch marks of cave bears, now extinct.  The 3-D filming brings the region, the river valley, the rock face and the interior of the cave to vivid life, and gives a context for the paintings beyond photographs or conventional film.
