'''Alligator''' is a 1981 horror/comedy film, directed by Lewis Teague and starring Robert Forster, with a screenplay by Creator/JohnSayles, in which "Ramon", the eponymous beast, runs amok in the Chicago sewer system after feeding on covertly discarded growth hormone. The film is notable for being among the first of the slew of ''Film/{{Jaws}}'' homages/rip-offs to be produced by the American movie industry. Unlike 99% of the horrors that have come lurching along in its wake, the humor is intentional, the human characters are sympathetic, and the flick is worth seeing.

A sequel was released in 1991, subtitled ''The Mutation''.

%%* AbsurdlySpaciousSewer
* BrickJoke: Because in the middle of the film, [[spoiler: one of the heroes arrested a man for selling a baby gator for pet and telling the other cops to flush this gator.]]
%%* ChildrenAreInnocent: Subverted more than once.
%%* CorruptCorporateExecutive
* CowboyCop: The hero's reputation, even though it's not exactly deserved.
* DaChief: A more sympathetic and intelligent version than usual.
* EgomaniacHunter: The ill-fated Col. Brock.
* FollowTheLeader: To ''Jaws'', with several of its plot-points being repeated, including [[spoiler: a child being eaten by the beast, setting off a horrific media circus.]]
* GreatWhiteHunter: Again, an overt parody in the form of Col. Brock.
* HereWeGoAgain: The film ends with [[spoiler:another alligator getting flushed into the sewer.]]
%%* HotScientist
* IntrepidReporter: Subverted, in that the guy is an obnoxious jerk, but genuinely goes [[GoingForTheBigScoop looking for scoops]], eventually [[spoiler: taking [[ApocalypticLog crucial pictures]] of Ramon, even as he is devoured.]]
* InfantImmortality:
** Averted when on a dare, a kid jumps off the diving board of his backyard swimming pool at night while the alligator is momentarily staying in it. He realizes at the last moment what is happening and tries to step back, but his friends push him in anyway because they didn't see it and think he chickened out.
** However, it was played straight when a little girl toddler was in the back yard with her mother's wash. Mom hears the phone ring, goes in to answer it, and along comes the titular beast. Mom sees the monster leave the yard, screaming and crying as she looks for her child. Then the little girl lifts up the clothes basket she was hiding under!
* KarmicDeath: Ramon [[spoiler: kills the Corrupt Corporate Executive whose experiments inadvertently created him.]]
* MadBomber: This is literally the name of one character in the credits. Might called a case of [[spoiler: [[ChekhovsGun "Chekov's Explosives"]]...]]
* MyGodWhatHaveIDone: The kids at the pool, not the one who's dead. They thought it's just a prank, but the moment they saw they just fed their friend into a giant alligator, the sheer look of horror they had just screams off this trope.
%%* NeverSmileAtACrocodile
%%* NighInvulnerability: Ramon
* NightmareDreams: David has these from the first encounter with Ramon.
* PetBabyWildAnimal: Subverted. Ramon gets unceremoniously flushed into the sewer while still tiny, and his former owner then makes every effort to help kill him.
%%* ReptilesAreAbhorrent
* SewerGator: The film is about a deadly giant aligator killing humans in the sewers of Chicago.
* ShoutOut: The [[Film/TheThirdMan graffiti]] in the sewers, the name of the [[Series/TheHoneymooners sewer-worker]] Ramon kills.
* SuspiciouslyStealthyPredator: Because it just wouldn't be a ''Film/{{Jaws}}'' ripoff if the beast let anyone but the hero realize it was out there too soon, would it?
* StockFootage: The sequel uses snippets of footage from the first film's alligator sequences in some scenes.
* TalkingTheMonsterToDeath: Sarcastically suggested by the Hot Scientist, in reference to her motor-mouthed mother.

!!The sequel has examples of:

* KarmicDeath: The CorruptCorporateExecutive, whose casual dumping of toxic waste into the sewers created the giant alligator, is accidentally pushed into the lake and is soon eaten by the beast.
* MagicCountdown: Hawk leaves dynamite with timer on it in the sewer for the alligator, and hurriedly climbs back to the surface and warns other about how they have only ten seconds and they all scramble or safety. Cut back to the dynamite, which has noticeable amount of time left in the timer.
* NumberedSequels: With [[OddlyNamedSequel2ElectricBoogaloo Electric Boogaloo]].
