'''Troll''' is a 1986 [[BMovie B-Movie]] about [[AllTrollsAreDifferent Torok]], the [[ExactlyWhatItSaysOnTheTin Troll]] (no relation to {{ComicBook/Turok}} or [[{{Belgariad}} Torak]]). Directed by JohnCarlBuechler, this was misbranded as a horror movie, but it shares far more aspects with the UrbanFantasy genre, and in fact it works better when viewed as such.

The movie focuses on the Potter family. In case you are wondering, yes, there is a Literature/HarryPotter, two in fact (father and son), and this was ''way'' before the books. Wendy Potter, the obnoxious little girl of the family, is abducted by the troll, who then takes her form and infiltrates into the family. For the rest of the movie, he basically turns the neighbours into plant pods to generate more trolls to take over the world. Why he didn't do that before nobody knows. Anyway, Harry Potter Junior, played by a teenage NoahHathaway, realises his sister was replaced... after watching two sci-fi movies. [[WhatAnIdiot And even so, he thinks she's an alien]]. It takes a meeting with Eunice St. Clair to realise what is really happening, and then he solves everything.

It's worth noting that this movie '''has no sequels'''. The SoBadItsGood ''Film/{{Troll 2}}'' is actually an Italian movie with no relation whatsoever to it, and has goblins instead of trolls. The two ''Troll 3'' movies (original names being ''TheCreepers'' and ''QuestForTheMightySword'', respectively) are even less related; the first has no humanoid creatures or magic whatsoever, instead featuring radioactive plants, while the later does feature a few trolls/goblins/whatever but it was meant to be part of the [[Film/TheBladeMaster Ator]] series.

!!Tropes present in Troll:

* AllTrollsAreDifferent: Literally; all the trolls produced differ greatly from Torok.
** The only actual troll is Torok. The other creatures he spawns from the tenants are assorted fey folk. Damned UGLY fey folk (excepting Creator/JuliaLouisDreyfus), but fey folk nonetheless.
* BiggerOnTheInside: The apartments achieve this as a result of the RealityWarping going on
* BrainlessBeauty: Harry Potter Junior (played by Noah Hathaway, who at the time aged quite nicely since his role as [[Film/TheNeverendingStory Atreyu]]) is fairly nice looking, but comes across as rather stupid.
* BrownNote: The horn Eunice blows to shut the singing faeries up.
* CoolOldLady: Eunice, once she and Harry Jr. start getting to know each other.
* DolledUpInstallment: The so called "sequels" were all original movies renamed in order to look like sequels to this movie. Considering [[SugarWiki/NeedsMoreLove how famous this movie is]], one has to wonder ''why''.
** ''Troll'' grossed well in 1986 for a BMovie, and had name recognition in the late 80's.
* EverythingsBetterWithPrincesses: Somewhat subverted; Eunice was a princess, but she decided to become a witch.
* {{Fanservice}}: It really just depends if you're either into girls running around wearing nothing but leaves covering naughty bits or into teenager boys showing their naked torsos, but either way you will be satisfied. An in-universe case for Torok, who stares at [[spoiler:the body of the girl he turned into a fairy/elf/whatever]].
* TheFairFolk: Torok began his evil ways when he was still an elf (he was turned into a troll for punishment), and after mistaking a midget for an elf [[spoiler: he turns him into an actual elf]]. He also [[spoiler: turns a woman into some sort of fairy that lures her boyfriend]], and it is slightly implied Eunice may be a fairy.
* GreenThumb: One of the few times not only a villain has it, it also doesn't fall into GoodPowersBadPeople because of the way it is used.
* IdiotPlot: [[invoked]] The New York Daily News review noted that some movies were for 13 year olds, and other movies were for morons - and that ''Troll'' was for [[BreadEggsBreadedEggs 13 year old morons.]]
* KidHero
* OhCrap: Eunice wears a good one when her own mushroom faerie joins in on the ''Cantos Profanae''.
* OurDemonsAreDifferent / OurGargoylesRock: A gargoyle/demon thing attacks our protagonists in the end.
* PetTheDog: Torok does care about the little girl, and so [[spoiler: he kills the demon/gagoyle thing mentioned above]]. He also [[spoiler: turns a person suffering from cancer into an elf]].
** [[spoiler: Killing the creature that attacked Wendy has nothing to do with his caring about the girl. He can't allow her to be harmed because her death would basically make the new faerie kingdom he was trying to create implode. She was the keystone for the whole thing.]]
* RealityWarping: seems to be a side effect of the ring's transformation process although from the transformed perspective it's RealityWarpingIsNotAToy.
** It isn't a side-effect, it's part of what Torok is plotting. He's trying to recreate a faerie kingdom in the apartment building, so that he can have another go at what got him turned into a troll in the first place.
* ShoutOut: One of the faeries is [[Film/CreatureFromTheBlackLagoon the Gill Man]].
* SpawnBroodling: Although the plant pods seem to be the same people that are killed, with a different body, it otherwise fits since they become rather mookish.
* WhenDimensionsCollide: Torok's intended plan. First turn all the apartments into pocket dimensions that once complete would expand and absorb the outside universe.
