"Battleship Potemkin," one of the most powerful and influential films of the silent era, has been restored to its original, uncensored version. Some of the Soviet film’s more violent images had been removed, as had some of its more revolutionary speechifying. German restorers, working with some of the excised footage, labored for three years on the longer version. Directed by Sergei Eisenstein, "Potemkin" tells the story of a mutiny on a Russian battleship.
