When Avatar comes out April 22 on DVD and Blu-ray, there won't be a thing on it besides the movie. The filmmakers

say they want every bit of the disc's space devoted to the audio-video presentation of the feature film. "We went to Fox and told them that, for this movie, we wanted to do something really special and reach for the best presentation of any film in the history of the format," producer Jon Landau told the Los Angeles Times. "... Everything that is put on a disc takes up room — the menus, the extras, the trailers and studio promotions — and we got rid of all of that so we could give this movie the best picture and sound possible." Of course, such a move doesn't preclude a release from including supplemental material on other discs in a set -- and, in fact, the Times reports that a multidisc version with extras will be out in November, just in time for holiday giving. And if you needed any proof that home-based 3-D technology is moving too fast for available content, with the recent introduction of 3-D TVs and Blu-ray players, not even the biggest 3-D movie ever made will be released initially in that format for home viewers. The filmmakers say there's not a large enough audience for it.
