The Boat

The Boat is the English release title of Das Boot, a 1981 West German war film directed and written by Wolfgang Petersen from the novel by Lothar-Günther Buchheim, starring Jürgen Prochnow.¹ The film dramatizes an authentic 1941 U-boat operation in which the German submarine U-96 sailed from La Rochelle, France, to attack British freighters in the Atlantic.² Identity is confirmed against filmportal.de, the database of the Deutsches Filminstitut, which records the original title, the 1941 operation, and the German premiere dates.²

Plot and production

The picture follows one Atlantic patrol, beginning when the submarine leaves La Rochelle in German-occupied France and ending when it comes back to harbor a few months afterward.³ An encrypted radio message orders the crew to break through the Strait of Gibraltar, straight through the Allied destroyer screen. The desperate attempt fails; a renewed air attack hits the boat hard and it sinks to the seabed.⁴

Production method. After measuring and photographing the Type VII submarine displayed at Kiel and scrutinizing original blueprints, the production architects built a floatable, diesel-powered surface model, very precise life-sized interiors, and scale models of 1:6, 1:12, and 1:25.⁵ The whole interior mock-up, with all crew and gear, was mounted on an electronically controlled, hydraulically operated platform 12 meters above the studio floor, where diving angles of up to 15° and rolling angles of up to 40° could be simulated.⁵ Much of the film was shot in a real submarine to create a genuinely claustrophobic atmosphere.⁷

The famous running shot through the boat was achieved with a handheld gyro-stabilized device: the cameraman, wearing elbow pads and a crash helmet, ran through the compartments and dove through two bulkhead hatches while underway, recreating the wartime maneuver of tilting the boat forward for diving.⁵ Because the handheld camera's noise prohibited on-stage sound recording, the German and English versions were taped later in a synchronization studio.⁵ Scale-model shooting began in the North Sea off Heligoland using the 1:6 submarine filmed in slow motion, and the Strait of Gibraltar scenes were shot on Lake Constance.⁵ First shots with an eleven-meter model were filmed in October 1979 off an island, and after 166 shooting days the film was in the can.⁶

Principal photography ran from July 1980 to June 1981 at La Rochelle, off Helgoland, off Immenstaad on Lake Constance, and at the Bavaria Atelier in Munich-Geiselgasteig.²

Interpretation and German memory

The film's framing is anti-Nazi in a specific way: the crew's loyalty lies with the navy and their captain rather than with the Nazis.⁷ Petersen's vision emphasized the ability of man to suffer and endure, rather than any innate aggressiveness, and the German distributor advertised the film as a "Voyage to the limits of human endurance."⁵

German criticism has focused on what that framing leaves out. Filmdienst judges the film ambivalent because it neither reflects the political situation of World War II nor keeps its distance from the conduct of war.⁸

Origins: Buchheim's novel and the real U-96

The movie is a screen version of the novel by German author Lothar G. Buchheim, drawing on the time he spent as a war photographer serving on a U-boat during World War II.⁷ The story rests on a real operation: in 1941 U-96 put out from the harbor of La Rochelle to torpedo British freight ships in the Atlantic.²

Petersen, born in Emden in 1941, said Buchheim's novel was the first book he had read that told how war really feels.⁵

Versions and releases

The film exists in three principal versions. The theatrical cut runs 149 minutes (4069 m) and premiered in Germany on 17 September 1981 at the Mathäser Filmpalast in Munich and the Arkaden in Wiesbaden.² The television version runs 308 minutes in three parts, first broadcast on ARD on 24 February, 27 February, and 3 March 1985.⁴ The Director's Cut, FSK-certified on 6 November 1997 at 208 minutes (5705 m) for ages 12 and up, received a German theatrical release on 11 December 1997.²

Sources differ slightly on the longer cuts. Variety describes the miniseries as a six-hour TV version and the 1997 Director's Cut as 207 minutes,³ while the German film databases give 308 minutes and 208 minutes respectively.²^•⁴ Filmdienst records that the 1997 long version extended the 1981 classic by around 60 minutes and was acoustically upgraded with a digital sound mix and surround effects to the level of Hollywood productions.⁸

Reception and box office

In the 1980s, the US Naval Institute observed, Das Boot proved hugely popular in the United States, possibly since American audiences had few other films showing the war through the eyes of the losing side.⁵ In a review published at the time of the film's release, Variety judged it easily the costliest German production since World War II, and perhaps ever made in German cinema.³

The home-video database blu-ray.com lists box office figures of $11,487,676 and $84,970,337 across listed release dates including 1981–1982 and the 11 December 1997 Director's Cut release; the figures are not itemized by territory or version, and no other retrieved source gives a gross figure, so they should be read with caution.⁹
