History Trivia / LittleNemoAdventuresInSlumberland

** At one point the art style for the film was closer to the comics [[https://www.deviantart.com/filbarlow/art/1989-Little-Nemo-Character-line-up-503539230 shown by this artwork by filbarlow]] but a Disney-esk/Anima art style was chosen insted.
** Creator/GeorgeLucas was approached with the story but refused it; Creator/ChuckJones was also attached at some point, but left.

** The "Etiquette Song" was originally entitled, "The Chimpanzoo" and was written for and cut from ''{{Mary Poppins}}''.

* 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 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.
