->''"Crime is only...a left-handed form of human endeavor."''
-->-- '''Alonzo Emmerich'''

''The Asphalt Jungle'' is a 1950 [[TheCaper Caper]] crime drama directed by Creator/JohnHuston, [[FilmOfTheBook based on the novel]] of the same name by W. R. Burnett. It was the first major example of this trope while simultaneously being a deconstruction of it.\\
It's also considered a classic of the FilmNoir genre with an ensemble cast including Sterling Hayden, Jean Hagen, Sam Jaffe, Louis Calhern, James Whitmore, and, in a minor but key role, MarilynMonroe, an unknown at the time who was pictured but not mentioned on the posters.

After getting out of prison, Erwin "Doc" Riedenschneider goes to Cobby, a bookie, with an idea for a diamond heist. Cobby puts him in touch with Alonzo Emmerich, a crooked lawyer, who agrees to front Doc and his crew in the heist, who eventually include Dix, a "hooligan" who's been in and out of prison, his friend Gus, who runs a diner, and Louis, a safe-cracker. What none of them know is Emmerich, who has money troubles, is looking to double-cross the gang by taking the diamonds for himself.

A solid (though not spectacular) hit when it was first released, Huston's film is now considered one of the classics in its genre, and one of the most influential.

!!This film provides examples of:

* AffablyEvil: Doc is a gentleman gangster with good manners.
* AnyoneCanDie: And so they do.
* ArsonMurderAndLifesaving: Commissioner Hardy is dissatisfied with Ditrich's performance on duty and has three options for him: Reduce him to patrolman, bring him up for trial on charges of incompetence or ... give him one more chance to make good on his responsibilities.
* AvengersAssemble: The crew members for the caper are carefully selected by Doc.
* BackAlleyDoctor: Mentioned briefly, but ultimately averted:
** We can assume [[spoiler:Louis]] dies because the special doctor came too late or not at all.
** [[spoiler:Dix]] refuses to seek help from any kind of doctor which seals his fate as well.
* CallingCard: The nitro left in the safe by Louis.
* CaperCrew:
** '''The Mastermind:''' Doc.
** '''The Backer:''' Emmerich, though he turns out not to be trusted.
** '''The Burglar:''' Louis.
** '''TheBrute:''' Dix.
** '''The Driver:''' Gus.
* CityWithNoName: The city remains anonymous in the movie. Apparently, the exterior scenes were shot in Cincinnati. One version of the script even mentioned the city by name but it was taken out because ironically, Cincinnati was facing police corruption at the time.
* ConMenHateGuns: Doc.
-->"I haven't carried a gun since my twenties. You carry a gun, you shoot a policeman. Bad rap, hard to beat."
* TheDeterminator: Commissioner Hardy will stop at nothing to catch the crooks.
* DirtyCop: Lieutenant Dietrich.
* DirtyOldMan: Doc, and [[spoiler: he's HoistByHisOwnPetard because of it]].
** Emmerich as well ("Uncle Lon" indeed).
* [[spoiler:DownerEnding]]: And how!
* FatalFlaw: Almost like in a classic Greek tragedy, the characters had a weak spot which brought on their demise:
** If Riedenschneider had only left 5 minutes earlier rather than indulge his penchant for young girls, he'd have gone free.
*** Also, when the railyard security guard mentions that some guys bring young girls there to have their way with them, Doc becomes transfixed by the info and allows his face to be illuminated by the guard's flashlight, which causes him to identify and try to apprehend Doc and Dix.
** Emmerich and his penchant for luxury.
** Cobby and his craving for admiration.
** Dix and his gambling nature.
* GreyAndGrayMorality: The bad guys aren't all bad: one is a family man, one is tough but has an intense loyalty, even Dix has his generous side, a poor kid who just had a lot of bad breaks. And the good guys are hardly all good. One detective is corrupt, others are a bit slow, and the Commissioner comes across as a morally superior fanatic who sees everything in [[BlackAndWhiteMorality black and white]].
** Adding an extra punishment for Dix...that he will be remembered only as the Commissioner describes him to the newspapers, as "a man without human feeling or human mercy," with his human, brave, and honorable sides being forgotten.
* UsefulNotes/TheHaysCode: The police commissioner's spiel near the end when he tells everyone what a great job the police do. Also the fact that [[spoiler:all criminals involved in the caper get caught or die.]]
* HerrDoktor: Doctor Riedenschneider with his thick German accent.
* JackBauerInterrogationTechnique: Ditrich uses this technique successfully on Cobby.
* MealTicket: Emmerich, for GoldDigger Angela.
* TheMistress: Angela, for Emmerich.
* MsFanservice: MarilynMonroe, naturally...but in this early role, it's pretty [[DownplayedTrope downplayed]], comparatively.
* OneLastJob: Emmerich, Dix and Doc all plan to retire after the caper.
* ThePerfectCrime: Subverted. Riedenschneider points this out after he is struck by the foot patrolman later in the film, that no matter how well a thing is planned, some small detail will be the one to trip you up, like the alarm, the gun accidentally going off and wounding the "boxman" or getting stopped by a simple foot patrol checking the trainyards.
* PlethoraOfMistakes: The caper goes awry mostly due to [[TragicMistake emotional misjudgements]] and plain, simple bad luck.
* ReliablyUnreliableGuns: During his fight with the police man, Dix' gun drops to the ground and goes off, [[spoiler:fatally wounding Louis in the process.]]
* SuicideNote: [[spoiler:Emmerich]] starts to write one to his wife, but he has second thoughts and destroys it before blowing his brains out.
* VillainProtagonist: The story is told from the criminals' point of view.
