- Box Office Bomb: One of the biggest percentage-wise in the history of filmmaking. 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 bombs in the history of animated films (formerly the biggest until Delgo came along). Warner Bros. gave it both a limited release and Invisible Advertising, because they expected it to flop.
- Channel Hop: Warner Bros. released the film originally, but is now distributed by 20th Century Fox (now a part of Disney, ironically) due to Rupert Murdoch's ownership of Media Assets, the company that owned the film.
- Creator Backlash: In the July 2001 issue of "Toon Talk", Don Bluth admitted the film was disappointing, and regretted how it 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 let's 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.
- Creator Cameo: Bluth himself voices the radio announcer at the end.
- Creator Killer: This was the second-to-last film from the animation studio Don Bluth founded after he left Disney on really bad terms, and the last one to actually credit him (he ordered his name removed from The Pebble and the Penguin). This movie's Defcon-1 sweetness level and the fact that it directly contrasted his earlier work effectively soiled the studio's reputation for good.
- Dueling Works: With Disney's The Lion King (1994) in that both films are animated musicals about an exile living in banishment from a kingdom. Needless to say, The Lion King easily defeated A Troll in Central Park in 1994, seeing as how the former became the highest-grossing traditionally animated movie, while the latter became the biggest animated Box Office Bomb until Delgo in 2008.
- It was also this with the American theatrical and VHS releases of My Neighbor Totoro, which also involves two siblings who discover a nature-related creature and go on an adventure with it, which came out around the same time as this. In that case, Totoro won because it's more fondly remembered by kids from that decade than A Troll In Central Park was.
- Fake American: The parents, who for some reason are voiced by none other than Jonathan Pryce and Hayley Mills. They don't do a very good job of it.
- Name's the Same: Gnorga's Villain Song "Queen of Mean" is not to be confused with the song of the same name in Descendants 3.
- Old Shame: Gary Goldman stated that he and Don Bluth were not impressed with doing this film.
- Relationship Voice Actor: Gus (Philip Glasser) and Stanley (Dom De Luise) were Fievel and Tiger respectively in An American Tail.
- The Shelf of Movie Languishment: The film was completed in 1992 and then sat on the shelf for two years.
- Talking to Himself: In the Italian dub, Gus and Rosie are both voiced by Domitilla D'Amico.
- Troubled Production: Don Bluth made the mistake of shortening production, hoping that it would inspire more spontaneity among his crew. It wound up being his worst-reviewed film.
- Unintentional Period Piece: The Twin Towers remain visible in a number of scenes.
- What Could Have Been:
- 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.
- Buddy Hackett was initially the voice for Stanley, but Bluth ended up replacing him with Dom De Luise because he was easier to work with (for example, Hackett's contracts demanded a limited number of takes per line, while Dom was more than willing to do multiple takes of his lines).
