* AcclaimedFlop: Has a respectable 68% on Rotten Tomatoes 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."
* 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 many people 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 ''The Black Cauldron''.

* {{Lzherusskie}}: One of the gunners.
-->''We are wanting to move!''
* 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 ''Disney/LiloAndStitch'' 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.
** 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]].
