Das Boot (novel) in the context of "Das Boot"

Das Boot (German pronunciation: [das ˈboːt]; lit. 'The Boat') is a 1981 West German war film written and directed by Wolfgang Petersen, produced by Günter Rohrbach, and starring Jürgen Prochnow, Herbert Grönemeyer and Klaus Wennemann. An adaptation of Lothar-Günther Buchheim's 1973 semi-autobiographical novel of the same name, the film is set during World War II and follows the German submarine U-96 and her crew, as they set out on a hazardous patrol in the Battle of the Atlantic. It depicts both the excitement of battle and the tedium of the fruitless hunt, and shows the men serving aboard U-boats as ordinary individuals with a desire to do their best for their comrades and their country.

Development began in 1979. Several American directors were considered three years earlier, before the film was shelved. During production, Heinrich Lehmann-Willenbrock, the captain of the real U-96 during Buchheim's 1941 patrol and one of Germany's top U-boat "tonnage aces" during the war, and Hans-Joachim Krug, former first officer on U-219, served as consultants. One of Petersen's goals was to guide the audience through "a journey to the edge of the mind" (the film's German tagline Eine Reise ans Ende des Verstandes), showing "what war is all about".
