'''Alligator''' is a 1981 horror/comedy film, directed by Lewis Teague and starring Robert Forster and Robin Riker, with a screenplay by Creator/JohnSayles, in which UsefulNotes/{{Chicago}} policeman David Madison has to stop "Ramon", the eponymous beast, who is running amok in the city 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/remake was released in 1991, subtitled ''The Mutation''.

!!Provides examples of:

* AbsurdlySpaciousSewer: As noted by the quote above, it has a mighty big alligator freely wandering around in it.
* AntagonistTitle: The protagonist is Madison.
* AttackOfTheTownFestival: Ramon rampages through a high-society wedding.
* BigBad: Mr. Slade, the CorruptCorporateExecutive indirectly responsible for Ramón becoming giant.
* 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.]]
* CaliforniaDoubling: The film was not shot in Chicago.
* ChildrenAreInnocent: Subverted; two of them push their unwilling friend into a swimming pool, although [[spoiler: they certainly weren't trying to get him eaten]]. Also Madison has to deal with a [[BrattyHalfPint pretty mouthy kid]] who witnesses one of Ramon's attacks.
* CorruptCorporateExecutive: Slade. He orders the experiments which thanks to illegally discarded test-animal corpses leads to Ramon becoming the menace he is.
* CowboyCop: Madison's reputation, even though it's not exactly deserved.
* DaChief: A more sympathetic and intelligent version than usual.
* EgomaniacHunter: The ill-fated Col. Brock.

* HotScientist: Marisa Kendall, the reptile-expert/love interest who helps Madison in trying to kill Ramon.
* IntrepidReporter: Subverted, in that the guy is an obnoxious jerk whom Madison heartily dislikes, 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 is played straight when a little girl toddler is 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, and runs back out 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"]]...]]

* MotorMouth: The Hot Scientist's [[OneSceneWonder mother]].
* MyGodWhatHaveIDone: The kids at the pool, not the one [[spoiler: who's dead. They think it's just a prank, but the moment they see they've just fed their friend to a giant alligator, the sheer look of horror they have just screams of this trope.]]
* NeverSmileAtACrocodile: Hi there, Ramon!
* NighInvulnerability: Ramon is even bigger, stronger and better armored than a normal alligator, thanks to the aforementioned experiments. It finally takes [[spoiler: a bomb to finish him off.]]
* NightmareDreams: Madison has these from his 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, Of course, she has no reason to even know it's the same alligator.
%%* ReptilesAreAbhorrent

* ShoutOut: The [[Film/TheThirdMan graffiti]] in the sewers, the name of the [[Series/TheHoneymooners sewer-worker]] Ramon kills.

* TalkingTheMonsterToDeath: Sarcastically suggested by the Hot Scientist, in reference to her motor-mouthed mother.

!!The sequel has examples of:

* 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.
