* AcclaimedFlop: Has a respectable 68% 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''.
* 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: This movie was conceived back when ''Disney/TheLittleMermaid'' was... but the executives didn't allow Musker and Clements to make it until much, much later, and when it was made, the [[NeverTrustATrailer marketing campaign]] ensured not enough persons saw it by playing up the TotallyRadical aspects of it to the point of being obnoxious.
** It goes back even further than that; it was conceived as far back as 1985's ''Disney/TheBlackCauldron''.
* GenreKiller: ''Treasure Planet'' was one of a series of 2D animated bombs in the early 2000's that convinced Disney and rival [=DreamWorks=] Animation to drop the 2D film altogether. While DWA never did another traditionally animated film after 2003, Disney eventually returned to the pool with Musker and Clements' next movie, ''The Princess and the Frog''. Unfortunately, that and ''[[Disney/WinnieThePooh Winnie the Pooh]]'' did not help enough to revive theatrical 2D animation.
* {{Lzherusskie}}: One of the gunners.
-->''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.
* 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.
* 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.
