The bizarre story of a forgotten propaganda film made by the Nazis about the sinking of the Titanic. Made at the height of World War II, this film was conceived as the ultimate propaganda movie with the famous disaster recast as a story of Allied weakness and German courage. At the time it was one of the most expensive and ambitious movies ever filmed. The story of its creation rivals a Hollywood movie script with tales of betrayal, murder and massacre. It featured military personnel moved from the front to act as extras, the director was arrested and possibly executed on the orders of Propaganda Minister Joseph Goebbels and, in the last days of the war, the ship used for the filming was sank, as the Nazis tried to cover up the horrors of the Holocaust. For 60 years, the film was shrouded in secrecy. Now, using Goebbels's private diaries, unseen home-movies shot behind-the-scenes during the production and the original production design book, we reveal for the first time the extraordinary story of the Nazi Titanic.
