Das Boot is one of the most gripping and authentic war movies ever made. Based on an autobiographical novel by German World War II photographer Lothar-Guenther Buchheim, the film follows the lives of a fearless U-Boat captain (Jurgen Prochnow) and his inexperienced crew as they patrol the Atlantic and Mediterranean in search of Allied vessels, taking turns as hunter and prey. There’s very little plot, so the movie’s power comes from both its riveting, epic battle scenes and its details of the boring hours spent waiting for orders or signs of the enemy.
