To help Jim search for the treasure, Doppler commissions the ship RLS Legacy, commanded by feline Captain Amelia and stone-skinned first mate Mr. Arrow.

The ship's motley crew seem to be heavily influenced by cook John Silver, whom Jim suspects is the cyborg Bones warned him about.

A ruthless arachnid crew member named Scroop secretly cuts Arrow's lifeline, sending him into the black hole.

The film also features a cast including Tony Jay as the narrator, Austin Majors as Jim's younger self, and Jane Carr as Benbow Inn costumer Mrs. Dunwitty.

[8][9] The pitch was rejected by Michael Eisner, who knew Paramount Pictures was developing a Star Trek sequel with a Treasure Island angle (which eventually went unproduced).

[13] Angered at the rejection, Clements and Musker approached Feature Animation chairman Roy E. Disney who backed the filmmakers and made his wishes known to Eisner, who in turn agreed that the studio should produce the movie.

[21] The "mentor figures" for Jim Hawkins in the novel were Squire Trelawney and Dr. Livesey, whom John Musker described as "one is more comic and the other's very straight"; these two characters were fused into Dr. Doppler.

Clements also mentions that though the father-son relationship between Jim Hawkins and John Silver was present "to some degree" in the book, they wanted to emphasize it more in the film.

[22] Terry Rossio, who worked on the script, later argued the filmmakers made a crucial mistake turning Jim Hawkins into an adolescent.

[22] Patrick McGoohan was cast as Billy Bones at the suggestion of Corey Burton who played the smaller role of Onus in the film after having done an impression of him for a temp track.

[22] While designing for Treasure Planet, the crew operated on rule they call the "70/30 Law" (an idea that art director Andy Gaskill has credited to Ron Clements), which meant that the overall look of the film's artwork should be 70% traditional and 30% sci-fi.

[8] When asked if they drew inspiration from the previous film adaptations of Treasure Island for the character designs, Glen Keane said he disliked looking at previous portrayals of a character to "clear his mind of stereotypes", but that he drew some inspiration for the manner by which Silver spoke from actor Wallace Beery, whom he "loved because of the way he talked out of the side of his mouth."

McDonald's included promotional items such as action figures and puzzles in their Happy Meals and Mighty Meals, Pepsi-Cola placed promotional film graphics onto the packaging of a number of their soft drinks (Mountain Dew, Code Red, Sierra Mist, Mug Root Beer, Orange Slice, and Lipton Brisk), Dreyer's used their delivery truck panels to promote ice cream flavors inspired by the film (such as "Galactic Chocolate" and "Vanilla Treasure"), and Kellogg's included film-branded spoons in their cereal boxes.

[4] Dick Cook, then-chairman of Walt Disney Studios, expressed the hope that it would be a good way to distinguish themselves during the competitive holiday season.

[12] Treasure Planet was released on VHS and DVD in the United States and Canada by Walt Disney Home Entertainment on April 29, 2003.

The DVD includes behind-the-scenes featurettes, a visual commentary, deleted scenes, teaser and theatrical trailers, the music video for the song "I'm Still Here" by John Rzeznik, and a virtual tour of the RLS Legacy.

[54][55] Treasure Planet grossed over $12 million on its debut weekend, ranking at fourth place behind Harry Potter and the Chamber of Secrets, James Bond's Die Another Day, and Disney's own The Santa Clause 2.

[1][58][59] Its failure became apparent early on, as Disney's Buena Vista Distribution arm reduced its fourth-quarter earnings by $47 million within a few days of the film's release.

The site's critics consensus states "Though its characterizations are weaker than usual, Treasure Planet offers a fast-paced, beautifully rendered vision of outer space.

[66] Stephen Hunter of The Washington Post, who gave it 4 stars out of 5, stated that the film "boasts the purest of Disney raptures: It unites the generations, rather than driving them apart".

[67] Leah Rozen of People stated that the film "has imagination, humor aplenty and moves briskly", and that "the animation, combining traditional and digital techniques, is ravishing.

"[69] Kim Hollis of Box Office Prophets stated that "there's plenty to recommend the film – the spectacular visuals alone make Treasure Planet a worthwhile watch," though expressing disappointment because she felt that the characters were "not all that creatively rendered".

"[35] A. O. Scott of The New York Times described the film as "less an act of homage than a clumsy and cynical bit of piracy", and went on to say that it is "not much of a movie at all" and a "brainless, mechanical picture".

"[73] In 2020, Petrana Radulovic, writing for Polygon, praised the characters of Jim and Silver, as well as the "I'm Still Here" sequence and stated, the film "is a visual delight, a time capsule of the early 2000s in a way that perhaps no other animated movie of the era is.

In the sequel, Jim Hawkins and Kate, his love interest and classmate at the Royal Interstellar Academy, must team with Long John Silver to stop the villainous Ironbeard from freeing the inmates of Botany Bay Prison Asteroid.

[77] Following the box office failure of Atlantis: The Lost Empire (2001), Disneyland planned a second attempt to revive its Submarine Voyage ride with a Treasure Planet theme.

In October 2002, Disney Interactive released the naval strategy game Treasure Planet: Battle at Procyon for the PC, while in November, Sony Computer Entertainment released two separate Treasure Planet 3D platform action video games for the PlayStation (developed by Magenta Software) and PlayStation 2 (developed by Bizarre Creations).

[79] Bizarre Creations used Softimage's XSI engine for modeling, texturing and animation,[80] and released a Making-of video on their Facebook page in 2008.

[83] Jim Hawkins and John Silver also appear as playable characters in the video game Disney Heroes: Battle Mode.

[92][93] Many members of the crew who worked on the film including directors John Musker and Ron Clements, composer James Newton Howard as well as actor Corey Burton also celebrated its anniversary by partaking in a 3-hour livestream on YouTube on The Tammy Tuckey Show.
