'''''C.H.U.D.''''' (''[[ImAHumanitarian Cannibalistic]] [[WasOnceAMan Humanoid]] [[BeneathTheEarth Underground]] [[AttackOfTheKillerWhatever Dweller]]'') is a 1984 horror film about carnivorous mutants in the sewers of New York City. Street people begin to disappear and the police start to take notice. The eponymous creatures become bolder and come out to drag away more noticeable people, but the Nuclear Regulatory Commission covers up their existence until the last minute.

The movie spawned two sequels of questionable relation to the first.
!!This film provides examples of:

* AbsurdlySpaciousSewer: TruthInTelevision. New York is one of the few American cities that actually has these.
* BeneathTheEarth: It ''is'' a movie about mutants dragging people into the sewers.
* BigApplesauce
* BodyHorror: The monsters are horribly mutated humans. One scene takes it further, with the chud's neck stretching to a giraffe-like length for no explained reason.
* CrazyHomelessPerson: Averted and played straight. Many sympathetic and intelligent street people are shown. However, the C.H.U.D.s [[WasOnceAMan were homeless people]] and we get to see a couple in mid-transformation.
* DisposableVagrant
* EyeLightsOut: The C.H.U.D.s' eyes lose their radioactive glow when they die.
* GlowingEyesOfDoom: Perfect for looking creepy while crawling out of the sewer.
* ImAHumanitarian: The C.H.U.D.s seem to prey primarily on humans, even leaving the body of a dog dragged down with one of their victims uneaten.
* InitialismTitle
* LongNeck: One of the monsters starts extending its neck, which makes it all more easy to decapitate it with a sword.
* NuclearNasty: The heroes can track the things with a Geiger counter.
* ObstructiveBureaucrat
* TheReveal: [[spoiler: C.H.U.D. does ''not'' stand for Cannibalistic Humanoid Underground Dweller. It stands for "Contamination Hazard Urban Disposal" and the agency coverup.]]
* ShoutOut: ''WesternAnimation/TheSimpsons'' give a memorable one when Homer explains why he hates visiting UsefulNotes/NewYorkCity:
-->'''Homer''': ...and that's when the C.H.U.D.s came after me."
** Another episode reveals that C.H.U.D.s live under Springfield, along with [[Literature/TheTimeMachine Morlocks]] and Mole Men.
* WasOnceAMan: The C.H.U.D.s were originally homeless people who were mutated by radioactive waste left in the sewers.
