->'''Captain of the "Weser":''' So, what's it like down there, in a submarine?
->'''Der Leitende:''' It's... quiet.
->'''Captain of the "Weser":''' Quiet? Hmm.


''Das Boot'' is a [[TheEighties 1981]] German movie ([[TheFilmOfTheBook based on the 1973 novel of the same name]] by Lothar-Günther Buchheim) about the German submersible U-96. It is directed by Creator/WolfgangPetersen and stars, among very good German stage actors, Jürgen Prochnow as TheCaptain (commonly called ''Kaleun'', short for ''Kapitänleutnant'', or ''der Alte / the Old Man''). The movie is generally praised for its [[SubStory realistic portrayal of the claustrophobic atmosphere in a WWII sub]]. As noted by many visitors to Bavaria Studios, the interior set of the sub is actually even more claustrophobic than comes across on the screen.

By now you may wonder why nothing has been said about the plot so far. That is because the plot is quite simple. The U-96 sets sail. They then spend weeks trudging around the mid-Atlantic dealing with boredom, bad weather and a complete absence of Allied targets. They manage to attack one convoy and sink two ships, and get almost killed by the Allied navy. They then get ordered into a near-suicidal situation entering the Mediterranean sea through the British controlled Strait of Gibraltar, the most heavily defended seaway in the world, and are only spared from death pretty much by chance. They escape after a horrendous, odds-defying ordeal and limp home. The ship is then sunk the instant it docks by an Allied air raid. That's pretty much it: all the weeks-long stretches of boredom interspersed by hours-long stretches of terror that made up real German naval patrols.

''Fun Fact:'' When the movie premiered in the United States, the audience cheered at the caption at the very beginning that says that 30,000 of 40,000 German submariners died. The makers of the movie were really afraid at that moment, because that was supposed to be a tragic fact. By the end of the movie, however, the audience was also sympathetic to the submariners and, as said in the director's commentary, gave a standing ovation to the film.

!!This work contains examples of:

* ActuallyThatsMyAssistant: The captain of the supply ship ''Weser'' awkwardly assumes the young, clean shaved and [[SharpDressedMan uniformed]] 1WO is the Captain among a bunch of jaded and bearded sea-wolves.
* AllGermansAreNazis: Averted, as befits a film made by Germans, for Germans. Only the 1WO has any faith in Hitler's program. However, historically only partially accurate: of all the services, the German Navy was the least political, but the number of true believers in the Uboat service was among the highest.
** This may well be caused by the fact that the Uboat service had to receive so many replacement (to replenish casualties they sustained which was growing to such massive amount by 1943), as the service loses men (especially old experienced ones) they will tend to get replaced by newer ones that are either heavily indoctrinated or similarly more entrenched with the Nazi ideology. During the earlier part of the war, they probably are as apolitical as the other Kriegsmarine aspect, but as the staggering casualties mount, they get slowly refilled with men who are more aligned with the Nazi.
** TheCaptain even states that the newer crewmembers he has are not long out of the Hitler Youth.
* AnachronismStew: While the song itself is old enough, the recording of "It's a Long Way to Tipperary" used in the film is sung by the Red Army Choir and post-dates the war by decades.
* AnyoneCanDie: The text at the top of the page suggesting a 75% mortality rate for German submariners? It's not an exaggeration. No other branch of any armed service suffered such a high casualty rate and continued to function.
** The German U-Boat crews suffered higher casualty rates than even the Japaneese Kamikazes.
* ArtisticLicenseHistory: While the film does give an excellent feel of what life was like on a U-Boat, the film takes place in autumn 1941, when the U-Boat Force was doing much better than it would later on.
* AuthorAvatar: Leutnant Werner. The author of the original novel was himself a WWII naval correspondent, and the novel was heavily based on his own experiences.
* BadassBoast: "They are in the casino, celebrating [[OnlyMostlyDead our sinking]]... Not yet kameraden, not yet!"
* BeardOfSorrow:
** After weeks of being stuck on the u-boat, the 1WO is pretty much the only one who still bothers to shave.
** Nicely foreshadowed, when the Captain advises Werner to save some pictures for when they return, as the whole crew of mostly young new recruits will have beards by then.
* CantCatchUp: In time to turn the tide, anyway. The film opens at the beginning of the tipping point in the Battle of the Atlantic, when the second 'happy time' of hunting is over for the Germans, the Tommies have stopped making mistakes, and radar and active sonar are nasty but increasingly common factors for U-boat crews to ([[FailureIsTheOnlyOption often unsuccessfully]]) try to deal with. Near the war's end, the German navy had [[RealLife successfully developed]] the [[StupidJetpackHitler vastly superior]] Type-XXI submarine, but by then Germany's industrial capability was so devastated that only four ships of the type put to sea.
* CheeseEatingSurrenderMonkeys: Averted. It's mentioned that during their time in France many of the crew are ProperlyParanoid about spies, and in particular, Ullmann is terrified of what will happen to his French fiancée if LaResistance find out she's pregnant by a German.
* ChromosomeCasting: As one might expect given the setting and period, all of the characters are men.
* DamageControl: Stuck at the bottom of the Straits of Gibraltar, the entire crew has to help repair the boat.
* DarkAndTroubledPast: The stiff 1WO comes off less callous and more sympathetic in the mini-series when he reveals his fiancée died in an aerial raid on Cologne only weeks before the start of the patrol.
* DeathFromAbove: The crew are menaced by Allied aircraft several times. [[spoiler:The first time (shown only in the uncut edition) takes place right after they leave their port with minor equipment damage. The second time, Krichbaum is badly wounded. The third...[[DownerEnding well]]...]]
* {{Determinator}}: The chief engineer.
* DiabolusExMachina: Technically not an example because the ending is justified by the premise [[spoiler: and the aerial menace has been foreshadowed and shown]], but the DownerEnding does come suddenly out of nowhere and is guaranteed to shock a first time viewer.
* DiveDiveDive: Standard evasive maneuver against incoming or present danger. Deconstructed at Gibraltar when the immersion can't be stabilized due to the damage sustained and the boat keeps diving and diving out of control.
* DoNotDoThisCoolThing: Hotly debated. The author of the original book accuses the film of this, and some do side with him, but a huge number of people consider the movie to be the final, ultimate proof there is no glamour in war here, they say, merely suffering, misery, missed opportunities [[spoiler:and heartwrenching slaughter at the end]].
* DownerEnding: A pretty extreme example - there really wasn't a much stronger way for the efforts of the submarine's crew (and the entire German navy really) to be rendered totally useless.
* TheDreaded[=/=]HeroKiller: No Allied characters are shown, but their destroyers and airplanes fulfill this role. Evasion is the only option and a number of German aces of the deep have met their end against those hunters.
* DrowningMySorrows: The film starts with sub crews getting obnoxiously, paralytically drunk on shore leave. Given what they've just come from and are about to go back to you can't really blame them.
* EarWorm: Both in-universe and out-example. The crew of the U-96 are fond of "It's a Long Way to Tipperary", a UsefulNotes/WorldWarI British soldier song, and audiences of the film will likely not forget the song in a hurry.
* EnforcedMethodActing:
** The actors were not allowed to expose themselves to sunlight a few months before shooting. Also, the scenes were more or less shot chronologically, so that their appearances would change realistically.
** Jan Fedder, who played the injured sailor, really was injured when a special effect went wrong.
** In the scene at La Rochelle harbor near the beginning, actor Otto Sander, playing a drunk Phillip Thomsen really ''was'' drunk. Originally another actor was slated to play that part, but he was fired before filming began...ironically enough, because ''he'' was too drunk all the time.
** The cast were required to run drills of the emergency dive sequence, to ensure they were able to convincingly carry out the tasks the real crews had to perform during an emergency dive.
* EveryoneCallsHimBarkeep: Only a few of the enlisted crewmen have their names provided. Everyone else is "The Captain", "The 1WO" etc.
* FanDisservice: To produce exactly the effect intended, the stark realization of the cold dehumanizing grind of war. The film goes into detail about the toilet habits and medical well being (or lack thereof) of the crew, and has several lingering close up male naked butt shots as they either rush out of the loo in an emergency or are examined for disease.
* FatalFamilyPhoto:
** On two occasions Werner gets shown pictures of crew's family: The chief engineer shows him pictures of his wife and cadet Ullman shows him a picture of his (pregnant) French girlfriend who wants to marry him. [[spoiler:The end of the film sees Ullman die in the air raid, but the engineer subverts it by staying alive.]]
** In the uncut edition, Navigator Kriechbaum shows Werner a picture of his four sons, and says he has a fifth on the way. [[spoiler:He gets wounded by a British fighter and is last seen being loaded onto an ambulance at the base, being driven away seconds before the air strike.]]
* AFatherToHisMen: TheCaptain feels too old among ''his'' young children.
* FromBadToWorse:
** First they hit a three-week storm. Then they fall afoul of a destroyer. [[spoiler:Then destroyers with ASDIC. Then aircraft with radar. Then their hydroplanes break, nearly sinking them. Then, after frantic repairs and just managing to resurface the boat before they are crushed/drowned/suffocated, they are sunk in port by an air-raid.]]
** On the bright side, the journey home went pretty smoothly compared to the novel version. Along with the above, U-96 in the novel spent their return journey without periscopes, without radio, without sleep, with the entire hull shuddering and twisting around with every wave (they spent most of the return trip in escape gear, in case a large wave snapped the pressure hull open), without working torpedoes (they tried to sink a neutral liner with them and failed thanks to the first officer's incompetence), with engine fumes venting into the boat and only one intermittently working engine. Then upon coming in sight of the shore, they found themselves in a minefield (as they discovered when a friendly U-boat a few hundred meters away ran into one), were forced to stay perfectly still on the surface in full view of any passing enemy aircraft (due to risk of hitting said mines) and then were subject to an air raid that destroyed the nearby friendly U-boat, leaving U-96 to return to port with two dozen traumatized and hideously wounded sailors from another boat on their already ruined deck. [[spoiler: It was only at that point that the full air raid occurred and sank U-96 in port.]]
* UsefulNotes/GermanDialects: Each of the crew members speaks with a different dialect of German, as Wolfgang Petersen wanted to accurately reflect the diversity of the Third Reich in 1941. For instance, Pilgrim speaks with a Hamburg dialect (frequently saying "Moin Moin!"), Johann with an Austro-Bavarian accent, and Schwalle speaks with a Berlin dialect.
* GloryDays: The period in which German submarines had the upper hand is called "the happy times" and ended a few months before the beginning of the movie. The remaining aces get only more bitter and cynical.
* GratuitousEnglish:
** Aside from the afore-mentioned EarWorm, the Captain is fond of defiantly stating "Not yet!" JustifiedTrope in that he's directing his comments at the Royal Navy that's trying to sink his boat and kill his crew.
** Also Thomsen's "I am not in the condition to fuck."
* GratuitousFrench: In the novel, usually when the submariners are reminiscing about their time in France. The Old Man is fond of saying "Comme ci, comme ça" in dire situations, but by far the biggest offender is [[spoiler:[[MyGirlBackHome Werner's Girl Back In France]], Simone]].
* TheGreatRepair: A matter of life or death after the U-boat nearly hits rock bottom at Gibraltar.
* HeroOfAnotherStory: Thomsen, awarded with the Knight's Cross.
* HeroicBSOD: Johann, of all people, cracks under pressure and is subsequently terrified of the consequences, but the Old Man is lenient and Johann's top performance returns.
* HeroWorshipper: The crew of the supply ship Weser. Their enthusiasm is met with apathy by the submariners, but the food is welcome anyway.
* HopeSpot: [[spoiler: When the crew manage to resurface the submarine, epic music plays, and the scene cuts to the men happily singing "It's a Long Way to Tipperary".]] Then, they arrive at La Rochelle, and [[spoiler: are strafed by a British fighter-bomber.]]
* TheHunterBecomesTheHunted: A normal submarine patrol consists in sinking merchants and usually involves being chased by destroyers if the submarine can't stay undetected. The trope is used as the TagLine in the English box art.
* IfWeGetThroughThis: The Captain tells the crew "it's half a bottle of beer for each" if they can make it safely back to La Rochelle.
* KillEmAll: [[spoiler:The bombing of the sub at the end.]] Also an excellent example of {{irony}}.
* MyCountryRightOrWrong: Everybody aboard U-96 except the 1WO.
* NaiveNewcomer: Werner.
%%* NaziProtagonist
* NavalWeapons: The U-96 has to crash-dive to stay clear of destroyer's surface guns and then avoid their dreaded depth charges. Maritime flares are heavily used to illuminate the sea at Gibraltar. The submarine relies on torpedoes and also has a deck gun that is never used.
* TheNarrator: Acts as both TheWatson and MrExposition. He's on board as a journalist, thus it's his job to be inquisitive about everything, and pass on his knowledge. He has naval experience on surface ships but this is his first voyage on a submarine. The crew and officers sometimes pause to explain what they're doing to him but he often has to figure it out by observation
* NazisWithGnarlyWeapons: Well, yes, except that (again) only the 1WO is really a Nazi...
* PlotArmor: Played With and Deconstructed. Werner often tries to reassure himself that the boat can't sink because ''he's'' on the boat and ''of course'' he has to get out of this. After all, we're all the main character according to ourselves, and every one of the 75% of German submariners who perished felt the same way. [[spoiler: Ultimately Played Straight.]]
** [[JustifiedTrope Justified]] ForegoneConclusion, for those aware of the original book being written by a surviving eyewitness.
%%* PresentTenseNarrative
* PropRecycling: Steven Spielberg borrowed their full scale, floating replica of a German U-Boat, for ''Film/RaidersOfTheLostArk.''
* PuttingOnTheReich: 1WO.
* RecklessGunUsage: At the party at the beginning of the film, one officer staggers in drunk and begins firing his pistol randomly. Luckily, he doesn't hit anybody.
* ReCut: Several. ''Das Boot'' was 150 minutes long for its original theatrical release in 1981, then expanded into a five-hour MiniSeries on British and German television a few years later. In 1997 Wolfgang Petersen made a new Director's Cut edit for a theatrical reissue, which clocks in at just under 210 minutes. Both the miniseries and 1997 versions have been released on DVD.
* RedemptionInTheRain: Sort of. Johann makes up for his earlier breakdown by working tirelessly to repair a number of life-threatening leaks, and of course gets extremely wet in the process.
* ShellShockedVeteran: Thomsen. In the uncut version, while at the bar with Der Alte, the telephone rings and Thomsen cries out "ALARM!!!"
* ShootTheShaggyDog: [[spoiler:After all they've suffered and survived through the entire film, most of the crew die or get injured suddenly in an air raid the moment they get back home.]]
* ShownTheirWork:
** Every single detail of the internal construction of a VIIC U-Boat was painstakingly researched and included on the set. Literally the only difference between the internals of the set and the internals of a real U-Boat was that the set could have the side removed to allow for effective filming, though they only did that for one scene. A pretty short scene. The rest of the movie used a novel hand-held gyroscope equipped camera, as Steadicam was too bulky to be used inside the cramped set. The camera was specially designed and made to facilitate filming of this movie, and the gyroscopes were so noisy that most of the movie had to be dubbed.
** In addition to this, for the bridge of the U-Boat (where the lookouts stood, mostly exposed to the ocean), rather than stick with the then-standard method of throwing buckets of water at the actors to simulate waves hitting the ship in a storm, the crew built a specialist rig that would throw realistic amounts of water at the bridge at realistic pressure - this led to the previously noted incident where the amount of water caused an actor to lose his footing and threw him into a railing, breaking one of his ribs. The setup was realistic enough that when a shot called for a wave to come down the hatch into the control room (Extremely common and not at all a problem for the bilge pump), the exact same system in the exact same setup provided what could only perhaps be described as a 'column of furious water' - more than 4 metres and two hatchways down from the bridge.
%%* SilentRunningMode
* StockSoundEffects: ''Ping... Ping... Ping...''. Unlike most examples of the trope, only used when appropriate, since it implicitly tells the audience of the use of Allied active sonar.
* SubStory: TropeCodifier: not only universally regarded as the greatest submarine film, but also easily among the greatest war films.
* SuicideMission: The U-Boat is supposed to get to Italy via the Strait of Gibraltar, one of the most heavily defended Allied naval zones in the world.
* TheStoic: The 1WO is all about this in the initial stages of the film, being new to the war effort and a dedicated Nazi. He remains immaculately dressed and clean shaven for most of the film while the rest of the crew all become steadily filthier and more bedraggled with every scene. It is only in the latter stages of the film when even he cannot keep ontop of it all and slowly becomes dishevelled and unshaven too by the end of the film.
* ThoseWackyNazis: Averted, ironically. The story is primarily concerned with the ordeal of the submariners, to the point that, beyond the token "True Believer" and a brief mention of racial policy [[spoiler: (Werner recalls a colleague who attempted suicide after discovering he had slept with a Jewish girl)]], the Nazi ideology is never [[IncrediblyLamePun brought to the surface]].
* ThrowItIn: A fairly literal example. During one scene of the storm, the actor who played Pilgrim was swept off his feet by the rushing water and nearly thrown off the set. Bernd Tauber (Kriechbaum) realized he was suddenly missing and, with the cameras still rolling, helped him back to the hatch. Wolfgang Petersen did not realize it was an accident and initially wanted to do another take of this unscripted moment. The actor was actually injured and had to be partially rewritten so that Pilgrim spends a period of the cruise in bed.
* TorosYFlamenco: The soundtrack plays flamenco music when the crew arrive in Spain. They dock at Vigo, a northern city where that kind of folklore has no roots in real life.
%%* WarIsHell [Zero context example. Please provide context before removing the comment tags.]
* WeHaveReserves: The implied attitude of the off-screen Commanders.
* WeJustNeedToWaitForRescue: The crew are horrified that the Allies did not come to help the burning suffering crew of a ship they had bombed.
* WhatHappenedToTheMouse: We never find out what happened to Ullmann's French girlfriend, or 2WO's wife in Köln. Fairly justified, as the crew is not allowed to send personal messages and the movie ends just as they return home.
* WorthyOpponent: The Old Man frequently heaps praise on the tactics and skill of the British, often in the same breath as an utterance of "Tommy bastards", and often while on the point of being sunk by them. The crew even have a fondness for ''[[EarWorm It's A Long Way To Tipperary]]''.
