Werner Herzog's Cave Painting Documentary 'The Birth of the Modern Human Soul'

Werner Herzog's new film "Cave of Forgotten Dreams" is a stunning 3D documentary about a cave in France that is home to the world's oldest known human art. The legendary German director talked to SPIEGEL ONLINE about his life-long fascination with Stone Age cave paintings, the birth of the human soul and why he will only stop making films when he is taken away in a straitjacket.
