Das Boot is a 1981 German submarine film written and directed by Wolfgang Petersen, produced by Günter Rohrbach, and starring Jürgen Prochnow, Herbert Grönemeyer, and Klaus Wennemann. It has been exhibited both as a theatrical release and as a TV miniseries (1985), in several different home video versions of various running times, and in a director's cut version supervised by Petersen in 1997.
An adaptation of Lothar-Günther Buchheim's 1973 German novel of the same name, the film is set during World War II and follows German U-boat U-96 and its 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.
