Los Olvidados (1950, Mex.) (aka The Young and the Damned, and The Forgotten Ones)

In Luis Buñuel's nihilistic and grim cautionary tale - one of the greatest, and harshest, socially-realistic films ever made, filmed in stark black and white cinematography, and set in the slums of Mexico City populated by gangs of street kids:

• a juvenile delinquent gang in Mexico City led by amoral, older, violent reform school jail-escapee and miscreant El Jaibo (Roberto Cobo) committed horrific, sadistic acts of murderous brutality and petty crime, including the merciless robbery and beating of blind street musician Don Carmelo (Miguel Inclán), and the destruction of his drum
• in the next sequence set near a half-built, high-rise building, Jaibo (in denim overalls) vengefully beat rival Julian (Javier Amezcua) to death by striking him from behind in the head with a large rock (hidden in a fake arm sling) and then stole his money, in retaliation for Julian allegedly reporting him to police and sending him to jail
• the film's most sympathetic main character was the youngest gang member Pedro (Alfonso Mejía) in Jaibo's gang; he was bribed (with some of Julian's stolen money) to not report Jaibo's act of murder
• Pedro prostituted himself to survive by accepting homosexually-pedophilic advances; because he was the offspring of a rape, he was unloved by his widowed mother (Estela Inda) with four children
• in a famous, unsettling surrealistic dream sequence (in slow-motion and chiaroscuro), Pedro had visions of Julian's blood-stained face and dead body under his bed (he had witnessed the murder) with chicken feathers floating in the air, and then he saw his unloving mother floating toward him with a large slab of rotting raw meat as a lightning bolt struck (she normally deprived him of food); suddenly, Jaibo reached from under the bed with his long distended arm and snatched the meat, as the dream ended

Pedro's Surrealistic Dream: He Envisioned Julian's Dead Body Under His Bed, and His Mother with a Large Slab of Raw Meat

• other such disturbing imagery included the sensous, fetishistic imagery of teenaged Meche (Alma Delia Fuentes), the pretty younger sister of a gang member, who seductively poured milk on her thighs to wash herself, and the sight of an abandoned boy named Ojitos or Cute Little Eyes (Mário Ramírez) suckling from a goat's teat in the market square

• later (after a fist-fight with Jaibo), there was a poignant image of a bloody-nosed, battered Pedro looking through a dirty window
• to attempt to reform himself, Pedro took a job as a blacksmith apprentice; there, he was wrongfully set up by Jaibo for a theft crime (of an expensive knife); charged with the crime, Pedro was sent to a rehabilitation "farm school" center where he misbehaved and killed two chickens
• to test Pedro's honesty, the school's principal gave Pedro 50 pesos for an errand to purchase cigarettes; while on the way to buy the cigarettes, the menacing Jaibo stole the money, and the two boys got into a vicious fist-fight; although the fight ended in a draw, Pedro loudly announced that he had seen Jaibo kill Julian; the revelation was heard by blind street musician Don Carmelo, who reported it to police
• as a result, Jaibo retaliated by tracking down and vengefully killing Pedro (during a brief, dark scene)

Jaibo's Murder of Pedro

Pedro's Bloodied Corpse

• Jaibo died when he attempted to escape and was shot with two gunshots by the police as he left the murder scene - (during his surrealistic death, a mangy stray dog ran toward the camera and was superimposed over his face as he swooned and died)

Pedro's Body in Sack on Donkey, as Pedro's Mother Passed by

Disposal of the Sack Down a Garbage-Covered Cliff

• Pedro's body was found by Meche and her grandfather, and to avoid the police, his corpse was gracelessly disposed of; it was put in a sack and carried out of town on a donkey, to be dumped down a garbage-covered cliff -- while Pedro's mother passed in the street, ironically not knowing her lost son was dead
