The Big Boss (1971, HK) (aka Tang shan da Xiong, or Fists of Fury)

In writer/director Wei Lo's HK "karate - kung fu" martial-arts masterpiece, it introduced Bruce Lee in his first breakout starring role as a formidable opponent in choreographed fight sequences - and contained many of Lee's trademarked actions seen in future films:

• young Chineseman Cheng Chao-an (Bruce Lee), a city dweller who was sworn to non-violence to his mother (signified by the jade amulet necklace around his neck), moved from a northern province in China with his uncle to work in a blue-collar job at an ice factory in a rural area in Thailand with his extended family - mostly cousins, including his tough, martial-arts practicing cousin Hsu Chien (James Tien)
• upon meeting his only female cousin Chiao Mei (Maria Yi), Cheng was powerfully attracted to her and flirted with her
• the corrupt, heroin-drug-dealing and chief smuggler mobster Hsiao Mi (Han Ying-Chieh), known as the "Big Boss" - the head of the factory, was a skilled kung-fu master who lived in a grand mansion with lots of vicious German Shepherds; often, he would be surrounded by female masseuses
• the workers (many of whom were Cheng's co-working relatives) were often bullied or bribed to keep silent by the Big Boss' thugs and henchmen
• after Cheng's two cousins Chen (Peter Yang) and Wong (Li Hua-sze) discovered a package of white-powdered heroin that was being smuggled and hidden in a broken block of ice, the two inexplicably and bafflingly disappeared; it was learned that they were murdered when their bodies were chopped up by an industrial buzz-saw and hidden in frozen blocks of ice

The Mysterious Deaths of Cheng's Two Cousins
Heroin Hidden in Blocks of Ice	Retaliation for Witnessing Drug Trade: Buzz-Sawed Body

• when two of Cheng's other cousins, Hsu Chien and Ah Pei (Billy Chan Wui-ngai), went to the Big Boss to inquire about the whereabouts of their two cousins who had disappeared, they also went missing
• as a result of the many disappearances of the factory workers, they refused to work and revolted against the factory management; up to this point, Cheng had kept a restrained attitude in his retaliatory resistance efforts toward the Big Boss; during the chaotic fighting against thugs hired by the factory managers, Cheng's necklace was cut and broken - allowing him to break his vow of non-violence
• he decided to engage in his first major brawl against many of the Big Boss' henchmen at the factory; in an action sequence filmed with precise choreography, Cheng used energetic, deadly-accurate, lightning-fast high-kicks and swiveling movements to fight off numerous attackers; he then challenged the remaining group: "You wanna fight, I'll take you on!" - and when they resumed their attack, he dispatched all of the men (seen with POV kicks to their heads)

Cheng's Fight Against the Factory Henchmen of the Big Boss

• to buy off Cheng's opposition, he was appointed foreman of the ice factory, and he refrained from taking the side of the resistant protestors; during a dinner party, Cheng drunkenly dallied with sexy brothel prostitute Miss Sun Wuman (Marilyn Bautista); she ultimately warned him about the illicit drug-trafficking operation and cautioned Cheng to be careful because his life "might be in danger"; she showed him her naked right breast scarred by cigarette burns when she was the Big Boss' girlfriend

• soon after her warnings, the brothel prostitute Sun Wuman was murdered by the Big Boss' murderous son Hsiao Chiun (Tony Liu/Lau Wing), who threw a knife into her heart (sometimes edited out of some reels)
• to investigate on his own, Cheng discovered drugs in the factory, and body parts of his relatives hidden in blocks of ice; Cheng visited the Boss' mansion where he unrealistically jumped high over attacking German shepherds
• Cheng vengefully fought one-on-one against the Big Boss' son and some of his followers when surrounded - and powerfully punched one of the gang members through a wall, leaving a perfect impact silhouette or outline of his body etched in the wall; then, he pummeled Hsiao to death in the abdomen
• upon his return home, Cheng learned that all of his remaining family members had been murdered (and Chiao Mei had been kidnapped); he mused (in voice-over) about all of his murdered relatives (imagined in a row) and the promises made to his mother Chow Mei (Maria Yi) as he contemplated his next move: "I promised my mother I'd keep out of trouble. I tried to do it, too. But now, I'm really in a hell on this. What can I do? If I had any sense, I'd get out of here. If anything happened to me, who'd take care of Mei? She needs somebody now. She's over 70. But I can't just walk away from this. I just can't do that. I can't!"

Cheng's Final Showdown Against the Big Boss

• in the film's ultimate bloody and intense showdown sequence, Cheng entered onto the manicured green lawn grounds of the Boss' mansion; he calmly munched on a prawn cracker as six of the Boss' goons approached with knives to outnumber him
• meanwhile, hostage Chiao Mei escaped from her holding cell and sought to alert the Thai police; Cheng single-handedly and quickly vanquished the menacing group: ("Beat it, or I'll kill you, right now!"), and then the bare-chested, muscular Cheng faced off against the big Boss himself who was wielding two long knives
• there were two versions of the Big Boss' death: (1) in the R-rated version, he was simply stabbed in the chest with a knife that was thrown by the Big Boss but then deflected by Cheng's rapid kick back into him; (2) in the longer unrated version, Cheng was able to further ensure the Big Boss' demise with an infamous "death by finger impalement" technique into his rib-cage
• then, Cheng repeatedly punched the Boss' face before collapsing exhaustedly onto the Boss' dead body as the camera zoomed out; he surrendered to police when arrested for his murderous revenge, while the rescued Chiao Mei embracing him
