Werner Herzog. In a cave. With a camera. IN 3D.

That's pretty much all there is to say about Cave of Forgotten Dreams, Herzog's documentary about the Chauvet caves in the South of France. But those words alone are ridiculously promising. Especially if he goes mental with a chicken at the end.

Showing cave paintings dating back 32,000 odd years, this is one of those films that you don't see very often. Mainly because mad Germans aren't usually allowed in caves by themselves. Especially with a video camera.

Expect gorgeous art of horses, cattles, panthers, bears, and something to do with the fact that there is nothing in life but CHAOS, HOSTILITY AND MURDER. Read on for the trailer. Then work out when exactly Nic Cage will jump out of the shadows carrying a massive prehistoric iguana.

Cave of Forgotten Dreams is out on Friday 25th March. Presuming the futility of our existence hasn't killed us all in our sleeps by then.
