* AcclaimedFlop: Has a respectable 69% on Website/RottenTomatoes but didn't make back its $140 million budget.
* ActorAllusion:
** Scroop who was voice acted by Michael Wincott, who also played Rochefort in Disney's ''Film/TheThreeMusketeers1993'' had the same line (word) delivered exactly the same way after the same question; "Transparently."
** Scroop's Japanese voice actor Creator/RyuzaburoOtomo also voiced Crocodile in ''Manga/OnePiece'', who, like Scroop, is a pirate.
* BoxOfficeBomb: Budget, $140180 million. Box office, $109,578,115. It pretty much erased a lot of the profits Disney made from ''Disney/LiloAndStitch'' earlier in the year.
* CastingGag:
** In the Japanese dub, Silver is voiced by Genzo Wakayama, who voiced ''another John Silver'' in the animated version created by Creator/TMSEntertainment of the original story in the 70s.
** There's another Silver casting gag in the Italian dub. Silver is voiced by Renato Mori, who previously voiced a different version of the same character in ''ThePagemaster''.
* CreatorKiller: Very nearly became this for John Musker and Ron Clements, the ''Little Mermaid/Aladdin'' director duo who also helmed this film, as they did not work another movie until the end of the decade. The ExecutiveMeddling involved with Disney and the film's bombing led to them temporarily resigning from Disney, and they also considered reuniting with former boss Jeffrey Katzenberg at Creator/DreamWorksAnimation before the management shift in 2005 led to Katzenberg's own former boss Michael Eisner having to resign from Disney himself. Musker and Clements were brought back to Disney by John Lasseter circa 2006, and they moved on to ''Disney/ThePrincessAndTheFrog''.
* DoingItForTheArt: Musker and Clements spent ''sixteen years'' trying to get this movie made, first pitching it after the success of ''Disney/TheGreatMouseDetective'' and immediately following each successive movie they directed. They've openly admitted that the only reason they directed ''Disney/{{Hercules}}'' was because the studio heads flat-out promised that they would give it the green-light if they made one more financially successful movie.
* DuelingMovies: One of the most [[PyrrhicVictory destructive]] duels ever, in its race to be released before the long-delayed ''WesternAnimation/TitanAE''. Both animation teams were constantly looking over their shoulder at each other, according to WordOfGod:
--> [-Fatherless boy tries to solve his [[DisappearedDad daddy issues]] by going on a space voyage in search of a long-lost treasure, hidden on a BigDumbObject, with a [[IncrediblyLamePun less-than-stellar]] crew of galactic PettingZooPeople, one of whom is a ParentalSubstitute, [[spoiler:but proves to be TheMole,]] using a [[ImDyingPleaseTakeMyMacGuffin starmap]] [[YouWillKnowWhatToDo only he]] [[LivingMacGuffin can read]]. The villain [[spoiler:redeems himself in a TakeMyHand moment]] while trying to activate/deactivate the {{forgotten| phlebotinum}} DoomsdayDevice. Both films were deliberately marketed to single-parent Gen-X kids, with an uplifting {{Grunge}} soundtrack. One is about {{Pirates}} in a SteamPunk-ish/CyberPunk-ish AlternateUniverse, based on a [[Literature/TreasureIsland classic novel]]. The other is about SpacePirates AfterTheEnd, inspired by ''Franchise/StarWars'' and ''Series/{{Battlestar Galactica|1978}}''. Both films got an EarthShatteringKaboom.-]
** The sad part is neither film won; in fact both ended up tanking their respective studios because of divided profits. Both were good movies in their own right but couldn't hold up with competition. Don Bluth hasn't produced a movie since (though he's hoping for a theatrical adaptation of ''VideoGame/DragonsLair'') and this was almost the end of traditional animation for Disney.
* ExecutiveMeddling: The film was conceived as far back as 1985's ''Disney/TheBlackCauldron'' and was was first pitched by Musker and Clements in the same meeting as ''Disney/TheLittleMermaid''. Jeffery Katzenberg ruled in favor of ''Mermaid'' and again on two separate occasions, in the end promising to give it the green light if ''Disney/{{Hercules}}'' was successful. Then when it was finally produced, it was given a TotallyRadical [[NeverTrustATrailer marketing campaign]] that completely turned off audiences, ensuring that it would never be seen.
* GenreKiller: The film's massive failure against several successful [[WesternAnimation/{{Shrek}} computer]] [[WesternAnimation/IceAge animated]] [[WesternAnimation/MonstersInc films]] proved to be the final nail in the coffin for hand-drawn animation at Disney. They and their rival [=DreamWorks=] Animation dropped the medium a couple years later and Disney's [[Disney/ThePrincessAndTheFrog two]] [[Disney/WinnieThePooh efforts]] to bring it back at the end of the decade proved similarly unsuccessful.

-->''We are wanting to move!''
* MissingTrailerScene: Missing dialogue from the theatrical trailer:
--> '''Silver:''' You think a pup like you can take on the likes of me?!
--> '''Jim:''' Watch me!
* ScrewedByTheNetwork: Disney was utterly un-supportive of this movie as the execs felt that it didn't fit the company's image. It got very little advertisement once released which ensured its failure at the box office and has gotten no mention since then.
* SerendipityWritesThePlot: They mention in the {{DVD Commentary}} that they decided to kill off the pirates that were hardest to animate as early as possible.
* StillbornFranchise: A sequel was put into production before it was released but was cancelled when the film underperformed.
* VindicatedByCable: When released, ''Treasure Planet'' found itself overshadowed at the Box Office by ''Film/HarryPotterAndTheChamberOfSecrets''/ It ended up being a colossal flop that ended up [[GenreKiller turning Disney off of traditional animation.]] Several years later, separated from being overshadowed by ''Harry Potter'', ''Treasure Planet'' finally found its audience on cable.
* WhatCouldHaveBeen:
** Creator/AlanSilvestri was attached to score the film but pulled out to do ''Lilo & Stitch'' instead.
** There's a line cut from the ending that would have revealed it was [[MisterSeahorse Doppler]] who gave birth to the babies.
** In the theatrical release, there was a scene where after being injured, Captain Amelia looks at her hand, which is covered in blood. It showed that her injury is indeed very serious, but was cut for home release because of being very bloody. In fact, a number of discs were recalled from shops because the scene just got that far.
** There was going to be a sequel that would pick up where the first movie left off. More information [[http://animatedviews.com/2014/buried-treasure-the-ill-fated-voyage-to-treasure-planet-2 here.]]
** Originally, Jim would have fought Hands on the RLS Legacy instead of Scroop. Thomas Schumacher said to change it to Scroop because he's more menacing and they have too many characters in the film.
** Captain Amelia was originally going to be a Medusa before being changed to a CatGirl because her hair was too hard to animate.
* WordOfSaintPaul: [[http://steamcommunity.com/app/331970/discussions/0/618463738403378311/ In a Steam forum thread]] on the ''Battle at Procyon'' game, one of the game's developers stated that while the RLS prefix was chosen for Robert Louis Stevenson, the game's development team came up with the idea that it stood for Royal Light Ship.
