Little Nemo: Adventures in Slumberland

Little Nemo: Adventures in Slumberland, released in Japan as simply and credited in some territories as Little Nemo, is a 1989 animated musical fantasy film directed by Masami Hata and William Hurtz. Based on the comic strip Little Nemo in Slumberland by Winsor McCay, the film went through a lengthy development process with a number of screenwriters. Ultimately, the screenplay was credited to Chris Columbus and Richard Outten; the storyline and art style differed from the original version. The original soundtrack was penned by the Academy Award-winning Sherman Brothers. The film features the English dub voices of Gabriel Damon, Mickey Rooney, René Auberjonois, Danny Mann, and Bernard Erhard.

Even though it derived from an American comic strip, Little Nemo was animated by the Japanese company Tokyo Movie Shinsha and thus is often considered an anime film, although it was a joint production of Japanese and American animators and production companies.

The movie was infamous for being in development hell with many people, some of whom worked at Disney, Star Wars, Looney Tunes, & Studio Ghibli, figures such as George Lucas, Chuck Jones, Ray Bradbury, Isao Takahata, Brad Bird, Jerry Rees, Chris Columbus, Ken Anderson, Frank Thomas, Oliver Johnston, Paul Julian, Osamu Dezaki, the Sherman Brothers (Richard M. Sherman and Robert B. Sherman), Hayao Miyazaki (who was working at TMS at the time), and Gary Kurtz being involved with the movie before all dropping out.

The film was first released in Japan on July 15, 1989, by the Toho-Towa and in the United States on August 21, 1992, by the Hemdale Film Corporation for the dub. It received mixed reviews and was a box-office bomb, earning $11.4 million on a $35 million budget. However, it sold well on home video and has since developed a cult following.

Plot
A young boy named Nemo experiences a nightmare in which he is pursued by a locomotive. Upon awakening the next day, he goes with his pet flying squirrel, Icarus to see a parade welcoming a traveling circus. However, Nemo is unable to see the circus since his parents are too busy to take him. That night, Nemo imitates sleepwalking in an attempt to sneak some pie away, which acts against a promise he had made earlier to his mother, who catches him in the act and makes him run back to his room empty-handed. Upon falling asleep, Nemo is approached by figures from the circus parade. The circus organist introduces himself as Professor Genius and claims that they had been sent on a mission by King Morpheus, the king of a realm named Slumberland. The mission involves Nemo becoming the playmate of the princess, Camille. Although Nemo initially has reservations about interacting with a girl, he and Icarus decide to set off to fulfill his mission after being persuaded with a gift box of cookies from the princess.

Nemo is taken to Slumberland in a dirigible which he is allowed to drive, causing some chaos, and is introduced to King Morpheus. Morpheus reveals that he summoned Nemo to become his heir to the throne. Morpheus gives Nemo a golden key that opens every door in the kingdom and warns him of a door with a dragon insignia that must never be opened. Nemo is introduced to Princess Camille and the pair roam the entirety of Slumberland together. Afterward, Nemo meets the mischievous clown, Flip, who angers a group of cops and forces him and Nemo to hide out in a cave. There, Nemo discovers the door that Morpheus warned him not to open. Flip tempts Nemo into unlocking the door, which unleashes "the nightmare". Nemo rushes back to Morpheus' castle in time for his coronation ceremony, where Nemo is handed the royal scepter, the only thing capable of defeating the Nightmare King the ruler of Nightmare Land, should he ever return to Slumberland. In the middle of a dance session between Morpheus and Genius, "The Nightmare" reaches the castle and steals Morpheus away. As the partygoers search for a scapegoat, Flip and Nemo accuse each other, though the responsibility goes to Nemo who had the key.

Nemo awakens in his home, which floods with seawater and ejects him into the ocean. Genius discovers Nemo and tells him not to blame himself for all that has happened and that Flip is to blame, but Nemo accepting the situation pledges to find the King. When the two return to Slumberland, they rescue Flip from being shot out of a cannon because he has a map of Nightmare Land, where Morpheus is currently being held. Nemo, Icarus, Camille, Flip, and Genius set off in a tugboat in search of Morpheus. They are soon sucked into a whirlpool and find themselves in the goblin-infested Nightmare Land. The five come across a group of shapeshifting goblins called Oomps who wish to aid in the quest to rescue Morpheus. The Nightmare King sends a flock of gigantic bats to seize the rescue party. Nemo attempts to use the scepter but awakens in his bed instead. The Oomps appear in Nemo's room and the group travels to Nightmare Castle by flying through a portal in the sky. However, they are subsequently imprisoned in the castle, where the Nightmare King demands possession of the scepter. Nemo soon uses the scepter to finally eliminate and defeat the Nightmare King but almost at the cost of Nemo's life. Slumberland celebrates the fall of the Nightmare Kingdom. Camille escorts Nemo home on the dirigible. The two share a kiss before Nemo awakens in his room, where he apologizes to his mother for breaking his promise and trying to take the pie. Nemo's parents also agree to take Nemo to the circus. Nemo stares out the window as he looks forward to his new day.
