* ActorAllusion: Cloris Leachman voices Gnorga, the Queen of the Trolls in this film, and she had previously played a role as Cerena, Queen of the Trolls in the Creator/HannaBarbera Christmas special "The Little Troll Prince".
* BoxOfficeBomb: One of biggest in the history of animated films. The film had a budget of $23,000,000 and only grossed $71,368 domestically, which is less than one-third of 1% of its budget, making it one of the biggest {{box office bomb}}s in the history of animated films (formerly ''the'' biggest until ''WesternAnimation/{{Delgo}}'' came along).
* CreatorBacklash: In the July 2001 issue of "Toon Talk", Don Bluth admitted the film was terrible, and regretted how badly the film turned out;
-->“As it is never a good thing that a child is born prematurely, so it is with producing a film. Development of a script is like the development of a child in the womb; It takes time and must be done right. Building the movie, “A Troll In Central Park”, taught us this lesson, but indeed, the hard way.”I tell you all this in the hope that you might benefit from our foolish mistakes. Scrutinizing your own work is so important, but lets face it, we all are afraid of not measuring up, so we stubbornly cling to our own opinions, shutting out all others. Stanley could have been a richer character with more levels to his personality. Maybe he could have had a dark side, a troll side that he struggled with.”
* FakeAmerican: The parents, [[WTHCastingAgency who for some reason are voiced by none other than]] Jonathan Pryce and Hayley Mills. [[OohMeAccentsSlipping They don't do a very good job of it.]]
* HeyItsThatVoice: Gus and Stanley are [[WesternAnimation/AnAmericanTail Fievel and Tiger]] respectively.
* InkSuitActor: Gus bears a small resemblance to his actor Phillip Glasser.
* OldShame: Gary Goldman stated that he and Creator/DonBluth were not impressed with doing this film.
* [[ScrewedByTheNetwork Screwed by the Studio]]: According to the IMDB trivia. Gary Goldman stated that the reason the movie did so poorly at the box office was the fact that it was released without any promotion whatsoever, and what release it ''did'' have was limited. To which most people replied "Have you ''SEEN'' the thing?!"
* WhatCouldHaveBeen: Bluth has said that, had they not rushed their production, he would have wanted Stanley to be a much darker character with more abundant flaws.
* WritingByTheSeatOfYourPants: The film was apparently a failed effort for Bluth's team to invoke this trope.
