Morituri (also known as The Saboteur: Code Name Morituri) is a 1965 war film about the Allied sabotage during World War II of a German merchant ship carrying rubber, a critical product during the war. The film stars Marlon Brando, Yul Brynner, Martin Benrath, Janet Margolin, Trevor Howard and Wally Cox. It was directed by Bernhard Wicki. The filming occurred almost exclusively on an old German freighter. Plot Robert Crain (Marlon Brando) is a wealthy German engineer and pacifist who fled to India under a fabricated Swiss identity after being conscripted into the Wehrmacht at the start of World War II. He is blackmailed by English Colonel Statter (Trevor Howard) and the Allies into participating in a plan to seize a shipment of rubber, which is in short supply and essential for both sides' war efforts, that will soon be carried by the German merchant ship Ingo from Japan to Nazi-occupied Bordeaux. As all German merchant ships are under orders to scuttle themselves to prevent the capture of their cargoes by Allied forces, Crain's task is to use his engineering knowledge to disable the scuttling charges on the Ingo before the Allies move to take the ship. Crain is provided with fake documentation and a cover story: he is Standartenführer Hans Keil, a high-ranking SS officer needing to return to Germany. Aboard the Ingo, Crain finds the captain, Mueller (Yul Brynner), to be a patriotic German whose humanistic inclinations are at odds with Nazi principles. The first officer, Kruse (Martin Benrath), is a fanatical Party member who keeps a close eye on the captain, and the crew is a mix of Nazi loyalists and political prisoners who were pressed into service due to labor shortages. Crain begins covertly locating and disarming the scuttling charges. To deflect suspicion about his movements, he uses the charges to convince Kruse, who is unaware of the scuttling protocol, that he is secretly tasked with protecting the ship from a saboteur, and stokes Kruse's doubts about the captain's loyalties. Later, after one of the prisoners tries to kill Crain, he enlists them in a plan to have the Allies take the ship, while also winning Mueller's grudging trust by persuading him not to fire the scuttling charges when the ship is almost torpedoed by a Japanese submarine due to its disguise as a British merchantman. That submarine has two German Naval officers aboard, along with
