A dozen nonfiction films with real world impact -- helping free a man (''The Thin Blue Line''), energizing debate on climate change (''An Inconvenient Truth''), altering diets (''Super Size Me''), and more
This Soviet Union silent film is on this list not for any kind of political influence, but rather for its exuberant exploration of cinematic techniques. Director Dziga Vertov and his camera captured the daily city life of Odessa, Ukraine, and then constructed a dizzying narrative that featured split screens, double exposure, fast motion, freeze frames, jump cuts, and stop-motion animation. No movie has ever seemed quite as energized by the possibilities of the medium.
