Werner Herzog will reportedly join Martin Scorsese in the race to become the first internationally recognized auteur to adopt 3-D. More jaw-dropping still: The Bavarian master/raconteur/adventurer will use the technology on a documentary about cave paintings. "I can have only three people with me, and I can use only lights which must not create temperature," Herzog said of the filming process. "For each shot, because the technology is not really advanced, we had to build [our] own camera from zero using a specific configuration of lenses and mirrors. We are doing something nobody has done with 3-D." Sounds great! Not so great: The odds of finding an art-house theater that can project it. [Roger Ebert via The Guardian]
