Das Boot is among the most realistic of all World War II films and one of the most spectacular object lessons in manipulating and choreographing the space on the screen. Director Wolfgang Petersen manages to convey the long periods of boredom for the crew of a submarine while making that boredom interesting for the audience. The film is largely unconcerned with the issues surrounding World War II, instead focusing on the individual sailors aboard the sub. Cinematographer Jost Vacano is continually creative in finding new things to reveal aboard the cramped quarters of the sub, and the film's intensity is impressive. The scene in which the sub's captain (Jürgen Prochnow) sinks what he thinks is an unoccupied enemy ship, only to find that it isn't, is among the most memorable scenes in any war film. There are few films that can maintain interest for such a lengthy running time with so few sets to work with, but Das Boot does exactly that for all 210 minutes of the expanded, post-release director's cut.
