Atlantis: The Lost Empire is a 2001 American animated science fiction adventure film directed by Gary Trousdale and Kirk Wise, produced by Don Hahn, and written by Tab Murphy. Produced by Walt Disney Feature Animation, it stars Michael J. Fox, James Garner, Cree Summer, Don Novello, Phil Morris, Claudia Christian, Jacqueline Obradors, Florence Stanley, David Ogden Stiers, John Mahoney, Jim Varney, Corey Burton and Leonard Nimoy. Set in 1914, the film follows young linguist Milo Thatch (Fox), who gains possession of a sacred book, which he believes will guide him and a crew of mercenaries to the lost city of Atlantis.

Development of the film began after production had finished on The Hunchback of Notre Dame (1996). Instead of another musical, directors Trousdale and Wise, producer Hahn, and screenwriter Murphy decided to do an adventure film inspired by the works of Jules Verne. Atlantis: The Lost Empire was notable for adopting the distinctive visual style of comic book artist Mike Mignola, one of the film's production designers. The film made greater use of computer-generated imagery (CGI) than any of Disney's previous traditionally animated features and remains one of the few to have been shot in anamorphic format. Linguist Marc Okrand constructed an Atlantean language specifically for use in the film. James Newton Howard provided the film's musical score. The film was released at a time when audience interest in animated films was shifting away from traditional animation toward films with full CGI.

Atlantis: The Lost Empire premiered at the El Capitan Theatre in Hollywood, Los Angeles, on June 3, 2001, and went into its general release on June 15. The film received mixed reviews from critics. Budgeted at around , Atlantis grossed over worldwide, of which was earned in North America; its lackluster box office response was identified as a result of being released in competition with Shrek, Lara Croft: Tomb Raider, The Fast and the Furious and Dr. Dolittle 2. As a result of the film's box office failure, Disney cancelled a planned spin-off animated television series, Team Atlantis; an underwater Disneyland attraction; and a volcanic Magic Kingdom attraction based on it. Atlantis was nominated for several awards, including seven Annie Awards, and won Best Sound Editing at the 2002 Golden Reel Awards. The film was released on VHS and DVD on January 29, 2002, and on Blu-ray on June 11, 2013. Despite its initial reception, reception in later years became favorable and has given Atlantis a cult following and reappraisal from critics as a mistreated classic, due in part to Mignola's unique artistic influence. A direct-to-video sequel, Atlantis: Milo's Return, was released in 2003.

Plot

In the ancient past, Atlantis is an advanced civilization with robotics and aviation. However, an apocalyptic explosion causes a megatsunami that destroys all but the core of its capital city, which “sinks beneath the waves” per Plato’s attestation.

Thousands of years later, in 1914, Washington, D.C. archaeo-linguist Milo Thatch obsesses over finding Atlantis. His employers ridicule his theories, but he gains an unexpected ally in eccentric millionaire Preston B. Whitmore, a friend of Milo's deceased adventurer grandfather who also sought the city. Determined to honor his old friend's quest, Whitmore recruits Milo for an expedition to Atlantis, having recently uncovered the Shepherd's Journal, an ancient Atlantean manuscript containing directions to the city.

Aboard the submarine Ulysses, Milo meets his teammates: Commander Lyle Tiberius Rourke, Lieutenant Helga Sinclair, demolitions expert Vincenzo Santorini, geologist Gaetan "Mole" Molière, medical officer Joshua Sweet, mechanic Audrey Ramirez, radio operator Wilhelmina Packard, mess cook Jebidiah "Cookie" Farnsworth, and a platoon of mercenaries. Upon reaching a cave entrance leading to the lost city, the submarine is destroyed by a massive robotic leviathan, killing most of the crew. Milo and the survivors escape in smaller craft, navigating through the cave to emerge among ancient ruins.

Milo translates the journal, guiding the team through caves beneath a dormant volcano until they reach the remains of Atlantis. There, they are greeted by Princess Kidagakash "Kida" Nedakh, who, despite being around 8,500 years old, has the appearance of a young woman. She leads them to her father, King Kashekim, who orders them to leave. Learning that Milo can read their language—a skill lost to the Atlanteans over millennia—Kida asks for his help in uncovering their forgotten history and technology, without which the city has declined and resources have dwindled. Milo learns that Atlantis is powered by the Heart of Atlantis, a massive crystal that grants longevity and health to its citizens through the smaller crystals they carry.

Rourke betrays Milo and the Atlanteans, revealing his intention to steal the Heart for profit, despite knowing the Atlanteans will perish without it. He mortally wounds the King while seizing control and uncovers the crystal beneath the city. Sensing danger, the Heart merges with Kida, who is then captured by Rourke. He departs with the crystallized Kida and his mercenaries; Vincenzo, Molière, Sweet, Audrey, Packard, and Cookie refuse to take part in the Atlanteans' destruction.

As he dies, the King reveals to Milo that the devastation of Atlantis was caused by his attempt to weaponize the crystal's power. To protect the city, the crystal merged with a royal family member: Kida's mother. This allowed them to create a protective dome over the city center, but Kida's mother never returned. To prevent the crystal from ever merging with Kida, the King hid it, accelerating Atlantis' decline. He warns Milo that Kida will be lost forever if she is not soon separated from the crystal and pleads with him to save her.

Alongside his allies, Milo rallies the Atlanteans to reactivate their long-dormant flying machines. In a climactic battle, they eliminate Rourke and his mercenaries in the volcano but also cause it to erupt. Milo and the others fly back to Atlantis with the crystallized Kida, who ascends into the air and awakens titanic stone guardians able to erect a shield barrier over the city. With Atlantis saved from the lava, the Heart separates from Kida and remains suspended in the sky.

Milo chooses to stay in Atlantis with Kida, having fallen in love with her. Before returning to the surface, Vincenzo, Molière, Sweet, Audrey, Packard, and Cookie each receive a small crystal and a share of treasure. The six reunite with Preston on the surface and agree to keep their adventure a secret to protect Atlantis. Preston opens a package from Milo containing his own crystal and a note thanking him. The newly crowned Queen Kida and Milo carve a stone effigy of her father to join those of past rulers floating beside the Heart of Atlantis. The city stands restored to its former glory.

Production Development

The idea for Atlantis: The Lost Empire was conceived in October 1996 when Don Hahn, Gary Trousdale, Kirk Wise, and Tab Murphy lunched at a Mexican restaurant in Burbank, California. Having recently completed The Hunchback of Notre Dame,Kurtti 2001, p. 9. the producer, directors and screenwriter wanted to keep the Hunchback crew together for another film with an "Adventureland" setting rather than a "Fantasyland" setting.Supplemental Features: History: The Journey Begins at 0:08–3:05 Drawing inspiration from Jules Verne's Journey to the Center of the Earth (1864) and Twenty Thousand Leagues Under the Seas (1870), they set out to make a film which would fully explore Atlantis (compared to the brief visit depicted in Verne's novel).Supplemental Features: Story and Editorial: Finding the Story at 3:24–3:57 While primarily utilizing the Internet to research the mythology of Atlantis,Supplemental Features: History: Creating Mythology at 0:30–1:10 the filmmakers became interested in the clairvoyant readings of Edgar Cayce and decided to incorporate some of his ideas—notably that of a mother-crystal which provides power, healing, and longevity to the Atlanteans—into the story.Supplemental Features: History: Creating Mythology at 3:48–4:20 They also visited museums and old army installations to study the technology of the early 20th century (the film's time period), and traveled underground in New Mexico's Carlsbad Caverns to view the subterranean trails which would serve as a model for the approach to Atlantis in the film.Supplemental Features: Art Direction: Designing Atlantis at 5:42–9:18
