In the final part of The Story of Film: An Odyssey, movies come full circle. They get more serious after 9/11, and Romanian movies come to the fore, but then David Lynch’s Mulholland Drive becomes one of the most complex dream films ever made and Inception turns film into a game. In Moscow, master director Alexander Sokurov talks exclusively about his innovative films and then there’s a surprise: The Story of Film goes beyond the present, to look at film in the future.
