input question: Generate a question that has the following answer: Admiral Gunther Lutjens for the following movie plot: In 1939, Nazi Germany's largest and most powerful battleship, Bismarck, is launched in a ceremony at Hamburg with Adolf Hitler attending. The launching of the hull is seen as the beginning of a new era of German sea power. Two years later, in 1941, British convoys are being ravaged by U-boats and surface raider attacks that cut off supplies essential for Britain's abilities to continue the war. In May, British intelligence discovers the Bismarck and the heavy cruiser Prinz Eugen are about to break out of the Baltic and into the North Atlantic to attack convoys. Meanwhile, a spy in Norway spots the Bismarck and its escort Prinz Eugen; he attempts to alert the British by telegraph but he is discovered by the Germans and killed. The spy is only able to message that one of the ships is Prince Eugen but is shot before he can message that the second ship was the Bismarck. The man assigned to co-ordinate the hunt is the Admiralty's chief of operations, Captain Jonathan Shepard (Kenneth More), who has been distraught over the death of his wife in an air raid and the sinking of his ship by German ships commanded by Admiral Gunther Lutjens (Karel Atepanek). Upon receiving his new post, Shepard discovers Lutjens is the fleet commander on the Bismarck. Shepard's experience of conflict with Nazi Germany's Kriegsmarine and his understanding of Lutjens allow him to predict the Bismarck's movements. Shepard acts coldly to his staff but comes increasingly to rely on the coolness and skill of his assistant, WRNS Second Officer Anne Davis (Dana Wynter). Lutjens is also bitter. After the First World War, he considered that he had received no recognition for his efforts in the war. Lutjens promises the captain of the Bismarck, Ernst Lindemann (Carl Mohner), that this time, he and Germany will be remembered in greatness. Next morning near Iceland Bismarck and Prinz Eugen encounter HMSHood and HMS Prince of Wales. The four warships engage in a heavy battle. During the battle a shell from Bismarck hits the Hood slightly...???
