** The (now-)famed director Creator/HayaoMiyazaki was planning on making the film, and you can see Yoshifumi Kondo's pilot [[https://www.youtube.com/watch?v=QIS2JhWli_A on YouTube]]. However, he later left the project as he went off to Creator/{{Topcraft}} to do ''Manga/NausicaaOfTheValleyOfTheWind'', and left the film in the hands of someone else.

* DeletedScene: The DVD release has some extra scenes that weren't on the old VHS release, which patch up some minor holes in the plot. Most of the scenes were deleted due to NeverSayDie being enforced, so Nemo's life wasn't allowed to be shown to be in jeopardy by using the scepter. One place where the edits may have actually been an improvement is the intro; instead of a long and uninteresting opening credits sequence with the "Little Nemo" theme by Melissa Manchester (which appears on the DVD), they instead skipped the credits and played the song over Nemo's first dream.

** The "Etiquette Song" was originally entitled "The Chimpanzoo", originating as a CutSong from ''Film/MaryPoppins''.

* TheShelfOfMovieLanguishment: The U.S. theatrical release didn't come until 1992, three years after the Japanese one, despite the film being intended for the Western market all along. That it made it to the U.S. at all was at least in part to capitalize on a revived interest in animated features in the West after ''Disney/BeautyAndTheBeast'''s success the previous winter, which got several other foreign and/or shelved films into theaters at last.

** Another reason was that the shows from Creator/DiC and Disney were taking Creator/TMSEntertainment's production time away from ''Little Nemo''.

** The "Etiquette Song" was originally entitled, "The Chimpanzoo" and was written for and cut from ''Film/MaryPoppins''.
