After trying to make a name in Hollywood with the TV series ''Franchise/TheGreenHornet'' with mixed results, young actor and martial artist Creator/BruceLee traveled back to Hong Kong where his popularity as Kato was very high. There he met Raymond Chow and received the chance to star a film about martial arts. ''Tang Shan Da Xiong'', or ''The Big Boss'' (known in the U.S. as ''Fists of Fury'', in which case it is not to be confused with his later film ''Film/FistOfFury''), was the final result and the movie that started Lee's career and his way to becoming a legend of celluloid.

Cheng (Lee) is a Chinese man from Guangdong who has moved to Thailand with the help of his uncle. Prior to the start of the film, Cheng took an oath of non-violence at the behest of his mother. He becomes acquanited with his extensive family of cousins and soon comes to be very close to them, especially the sweet but vulnerable Chiao Mei (Maria Yi), with whom he develops a romance. Alas; getting a job at the ice factory where his cousins work; one day a block of ice is broken to reveal a bag of heroin inside. It turns out the ice factory is a front for a drug operation. The boss of the factory, Hsiao Mi, offers the workers (two of Cheng's cousins) who discovered the heroin a bribe to keep quiet. When they refuse it, he has them killed. Cheng and the remaining cousins start conducting an investigation. Hsiao tries to dissuade Cheng by promoting him to a foreman, but when this fails, he has the remainder of the family (sans Chiao) murdered. Cheng discovers them dead, and goes on a RoaringRampageOfRevenge.

Directed by Wei Lo (who would also discover Creator/JackieChan), ''The Big Boss'' was a breath of fresh air to martial arts films as it showed a flawed hero in a modern setting. The story (by Wei Lo and Bruce Lee) was very well developed and filled with suspense and action, and in a bold move for an action film, the main character remains almost inactive for the first half as Cheng must avoid violence due to his oath. The film not only launched Lee's career to the stratosphere; it influenced his own film-making style and the way future martial arts movies were done.

Wei Lo's usually restrained style was also influenced by his young actor's abilities; ''The Big Boss'' can be seen as his transition to a more explosive way of film-making that would be completed in ''Fist of Fury'' and the subsequent Jackie Chan films. The natural and raw look of the film added to the high dose of graphic violence (it is probably the goriest film in Lee's career, and consequently the most cut and censored) give the movie a harsh, gritty realism that adds to its charm.

As many have already said (and will continue saying without a doubt), Lee was a very charming actor whose presence filled the screen and owned it completely. That statement is proved here as we see him not as a killing machine, but as a common man who just wants to live peacefully, giving us many scenes of Cheng enjoying his new found family and struggling with his own vices. Lee's performance is very natural although one could say that he was basically playing himself.

To summarize, this is a watershed martial arts film both in terms of its star and the genre as a whole; and is essential viewing for anyone interested in either.

Not to be confused with the [[Franchise/MetalGear Metal Gear]] character who goes by "Big Boss".

!!This film provides examples of:

* ActualPacifist: Cheng has sworn off violence when the film starts. But when he gets pushed too far, he snaps. HARD. He goes from "wouldn't hurt a fly" to "your remains won't fit on a toothpick."
* AffablyEvil: Hsiao Mi first offers his workers membership in his cartel after they discover they're smuggling drugs. It's only after they politely refuse that he kills them. See WhatAnIdiot.
* AlliterativeTitle
* AllThereInTheManual: While not mentioned in the film, a few books released in the '70s at the time of the film's release mentioned that Cheng Chao An was forced to make his promise to his mother after his father was killed in a fight. In order to continue the family name, Cheng's mother wanted to make sure he would not fall to the same fate and that he'd live to raise his own family. Film historian Bey Logan even mentions this in an audio commentary.
* BMovie
* BigBad: Hsiao Mi
* CharactersDroppingLikeFlies: [[spoiler:All of Cheng's cousins except Chiao Mei are dead by the end of the film]].
* DecoyProtagonist: The film opens with Cheng being something of a common AudienceSurrogate who isn't allowed to fight and is awkward in city life. While Hsiu Chien is handsome, confident, protects the weak, lends money and can fight... [[spoiler: too bad he's TooCoolToLive.]]
* DownerEnding: [[spoiler: Bruce Lee's character is arrested at the end for the dozen or so murders he commits in avenging his family's death.]]

* ExcuseMeWhileIMultitask: Bruce Lee [[TheSnackIsMoreInteresting eats snacks]] and kicks some asses at the same time.
* FauxAffablyEvil: The titular Big Boss is extremely congenial and the kind of boss most employers would envy. Except, well, not really.
* FinishingMove: After [[HoistByHisOwnPetard kicking back a knife into his chest]], Cheng stabs Hsiao Mi in the ribcage...with his fingers.
* GivingSomeoneThePointerFinger: Observed when Cheng confronts the thugs at the factory after finally joining the fight.
* GoryDiscretionShot: Happens in one scene when Cheng's cousins get dismembered by the saw used to cut the ice blocks with when refusing Hisao Mi's offer.
* FunnyBruceLeeNoises: ''Averted'' in all versions except the oft ill-received Cantonese redub, which inserted stock cries from his other films.
* TheGlassesComeOff:
** Hsiao Mi deliberately removes his in the buildup to the final fight.
** He also does it in an earlier scene before demonstrating his martial arts skills.
* HongKongDub: The older export dub based on the Mandarin version.
* KissingCousins: They never kiss on-screen but Cheng and Chiao have feelings for each other
* ImpactSilhouette: Cheng punches one of his opponents through a wall, leaving a man-shaped hole in it.
* InfantImmortality: Averted [[spoiler:with Cheng's little cousin]]
* LipLock: Taken to an extreme with the heavily revised English dub, which takes every opportunity to make the lip movements match even if the dialogue bares little resemblance to what was said originally.
* MookFaceTurn: A few of Hsiao Mi's girls end up helping Cheng instead because of the way Hsiao Mi treats them.
* MsFanservice: After Cheng gets drunk post the party, a comfort girl is sent to, er, provide him some entertainment. The camera gives her a medium close-up enough to allow her disrobe...
* NiceGuy: In contrast to the stoic badasses that Bruce Lee usually liked to play, Cheng is a pretty mellow and gentle sort. Until his RoaringRampageOfRevenge, of course.
* NeverOneMurder: For the first half of the movie, the villains cover up their murders by murdering anyone who notices. They eventually realize they'll have to use more subtle tactics.
* OffhandBackhand: Cheng does this to two goons by throwing knives at them.

-->"That was dope."
-->"Huh? Dope in ice?"
* PosthumousCharacter: Old Wang.
* RageBreakingPoint: Cheng flips when his amulet is destroyed, breaking his vow metaphorically and physically.

* RoaringRampageOfRevenge: Cheng goes on one upon [[spoiler: finding his family murdered.]]
* ScrewTheMoneyIHaveRules: Two of Cheng's cousins refuse a bribe and an offer to join in drug smuggling. They pay for it with their lives.
* SexAsRiteOfPassage: A rather unexpected and dour play on this troupe happens in an entirely cut scene from the original release for The Big Boss, which took place between the family murder and the final fight at the Boss's compound. [[spoiler: Cheng returns to the Thai brothel he had visited earlier in the film to, ahem, "unwind" with another prostitute before he marched on with his suicide mission to the Bossí mansion. Presumably, the theme was that Cheng wanted to enjoy his final pleasures and re-establish his masculinity before either dying or getting jailed for a long time.]] Of course, the audience (and censors) did not take kindly to the movie's hero doing this, and the scene got axed from all future releases.
* TheSnackIsMoreInteresting: During the climax, Cheng faces the Boss and his mooks with a bag of chips in hand.
* SupportingProtagonist: Hsiu Chien [[spoiler:until he gets killed by the Boss's henchmen]]
* ShirtlessScene: Cheng gets one during the entire final fight.
* ThrowingYourSwordAlwaysWorks: Cheng demonstrates this multiple times. One of which includes an OffhandBackhand.
* VeryLooselyBasedOnATrueStory: The film was based on the true story of Cheng Chiu-on who fought the tyrants in Thailand. Cheng lived at the end of the 1800s and beginning of the 20th century. A memorial statue of him was erected in a garden in the Bangkok more than 80 years ago.
* WhatHappenedToTheMouse: The Ice Factory manager just disappears from the film after Cheng visits Hsiao Mi's house. What really happened is that Tso Chen, the actor who played the manager, and the film's assistant director, had a falling out with Lo Wei supposedly.
