A trailer has been released for Werner Herzog's new 3D documentary film: Cave of Forgotten Dreams. Herzog became interested in the Chauvet Cave in France where the movie is filmed, after coming across an article by Judith Thurman, one of the producers of the film. Herzog approached the French government and received special permission to film in the caves although he and his crew were under strict security to protect the underground art.
Herzog had some interesting things to say about the use of 3D: "Avatar was difficult to follow, romantic comedies should never be in 3D because it takes away from the emotionality of the film." The director went on to say "Let’s deal with 3-D as if we had 30 or 40 years of history behind us. We should be completely casual, as if we weren’t trying to impress everyone with the scope of it." There is still no word on when the film will hit be released, but March looks likely. The film has also already sold its TV rights to the History Channel.
