Mad filmmaker Werner Herzog may have conjured up a whole new genre when he directed his 3D art-house documentary Cave of Forgotten Dreams. That film—combining ancient cave art with eye-popping 3D technology—became an award-winning hit. Now, fellow German auteur Wim Wenders (Wings of Desire, Until the End of the World) has followed suit, creating a 3D documentary about avant garde dance choreographer Pina Bausch.
