* CashCowFranchise: Oh yes! What makes this even more annoying is that some people buy the stuff to look {{Goth}} or {{Emo}}, not because they've actually seen the movie. Ironically, Tim Burton seemed to try to prevent this to an extent, by refusing to do sequels and ruin the integrity of the movie for fans.
* ChristmasCreep: This was the inspiration for Tim Burton's poem. He wrote the original story after seeing Christmas decorations being put up in a store window display while the Halloween decorations were being taken down.
* CreatorCameo: Music/DannyElfman's head is inside the jazz trio's upright bass.
* DevelopmentHell: Burton used to be a Disney animator and came up with the concept, presented as a poem, in the early 1980s.
* DoingItForTheArt: Took over three years to film, utilizing up over a dozen ''sound stages'', a phenomenal amount of space. It was also a technical innovation: a special motion-control camera was created to allow for more sweeping cinematography.
* ExecutiveMeddling: Technically, this is why the film exists at all. Burton wrote the poem during his tenure at Disney, who, as per their policy, claimed it their intellectual property.
** The vampires playing hockey at the end of the film were originally using Burton's head as a puck.
** Disney moving the film under its [[Creator/TouchstonePictures Touchstone label]] rather then releasing it under the "Walt Disney Pictures" label due to the dark content. Future re-releases, both home and theatrical, would bring it back under the Disney name, after the Disney brand began to expand their demographic starting with the PG-13 ''Franchise/PiratesOfTheCaribbean'' series.
* FanNickname:
** [[OurDemonsAreDifferent Bone-Demon]]: Jack and any fan-made skeletons like him. Understood to be a sort of sub-species of either [[TheUndead Undead]] or demon. Usually used in the camp that thinks Jack and Sally have kids [[LampshadedDoubleEntendre by natural means]].
** Dr. Finkly: Dr. Finklestein, by his fans.
** Jewel: Dr. Finklestein creation/wife seen at the end of the movie. While there's no evidence that Finklestein's "Be careful, my precious jewel!" is a reference to her name, the fans use it anyways.
** Skeledoll: The name of Jack and Sally's fandom [[AlwaysFemale daughters]]. Can be either just ragdolls with bones or [[PatchworkKids a mixture of ragdoll and skeleton]].
** Spiral Hill: The hill where Jack gets his first song and where Jack and Sally have their BigDamnKiss. The English localisation of ''VideoGame/KingdomHeartsII'' calls it "Curly Hill" (the Japanese version calls it "Spiral Hill"), but if [[http://forum.tnbc.eu/viewtopic.php?t=2362 this poll is any indication]], fans massively prefer "Spiral".
* NonSingingVoice: Music/DannyElfman does the singing voice of Jack, while Chris Sarandon does the speaking voice. In "Oogie's Revenge", the trope is averted with Sarandon singing the songs.
** The Italian dub manage to avert this with Jack, having him dubbed by [[http://en.wikipedia.org/wiki/Renato_Zero Renato Zero]], a famous singer; as well as the German dub, with Music/NinaHagen as Sally.
* ProductionPosse: Tim Burton regulars like Catherine O'Hara, Glenn Shadix and even Danny Elfman have voice roles.
* RecursiveAdaptation: The film was based on an illustrated poem by Tim Burton. An anniversary edition of the poem added some more Burton illustrations more close to the film.
* ReferencedBy: The Music/Blink182 song "I Miss You" has a couple lines about living "like Jack and Sally" and having "Halloween on Christmas." Mark Hoppus wrote the song for his then-fiance (now ex-wife), both of whom were huge fans of the film and eventually had a ''Nightmare''-themed wedding.
* TalkingToHimself: Averted. Elfman does the voice of Jack Skellington and Barrel, but since he's the ''singing'' voice of Jack, he never runs into this trope. Likewise averted by Sally and Shock, who are both voiced by Catherine O'Hara but never share a scene with each other.
* WhatCouldHaveBeen:
** Originally, [[spoiler: Dr. Finklestein was going to be Oogie, disguised because he was jealous that Sally chose Jack over him and wanted to teach her a lesson.]] [[http://www.youtube.com/watch?v=GEOZbihCyoE See here]].
*** The line "You meddlin' stick figure!" was pretty funny.
** Another idea was to have the bugs exit Oogie Boogie's body and attack Jack. The storyboards for this can be viewed [[https://www.youtube.com/watch?v=gz-X3gVpm3g here.]]
** Also [[http://www.nightmarebeforechristmas.net/nightmare/script/2 This early script]] shows some changes, like we were going to see some of the other holidays at the beginning sequence, and "This Is Halloween" is considerably different from the final product (for example, Jack was going to come in on a {{Cool|Horse}} [[HellishHorse Undead Horse]]).
** There was also a couple of storyboards floating about the net (which seems to missing now) that had Jack and Oogie going at each other with [[FamilyUnfriendlyViolence freaking maces]].
** Also, Sandy Claws might have been voiced by VincentPrice.
** Music/DannyElfman was not the first choice to do the music. Instead, [[Film/TheNeverEndingStory Giorgio Moroder]] was offered the project but turned it down.
** Weirdest of all, the movie almost ''didn't'' get the Spiral Hill which codified GothSpirals! On the DVD commentary, Henry Selick indicated that Tim was unsure about the hill because of his mandate that "magic does not exist in Halloween Town." (Specifically, the unwinding part seemed like magic.) Selick only changed his mind by saying, "All right, then, it's a mechanical hill."
*** He used this same trick to get Lock, Shock, and Barrel's bathtub worked in, by adding a crank in the back and calling it mechanical.
** The poem in the opening narrative was recited by Edward Ivory, who also played the voice of Sandy Claws. An earlier recording (which is available on the original soundtrack) was several lines longer and read by Actor/PatrickStewart. Hear it in all its glory [[https://www.youtube.com/watch?v=tY3MAguzzKA here.]]
** Stewart also provided a coda that wasn't used, where it was revealed that the narrator was in fact Sandy Claus himself, and had visited Jack years later, having "grown quite fond of that skeleton man". It is also revealed that Jack had [[BabiesEverAfter several baby skeletons running around]] (presumably with Sally). This verse is also available on the original soundtrack, and can be heard [[https://www.youtube.com/watch?v=udDDa1aAw_o&list=PLBAFD34845E5AE435#t=29 here.]]
** At one point Burton considered making a follow-up titled ''The Unlucky Clover'' based around St. Patrick's Day.
