* {{Anvilicious}}: Lydia is fascinated by death because her parents misunderstand and neglect her, but the Maitlands do nothing but reminisce about how much they enjoyed their lives, even with hassles like a NosyNeighbor and their [[LawOfInverseFertility lack of children]]. In the end they find a joyous existence only by making peace with the Deetzes and becoming a second set of parents for Lydia. DeathIsDramatic only for the dead, and it sure as sunrise ''doesn't solve problems.'' SuicideIsShameful, and even a "natural" death is a '''cast-iron pain in the ass.'''
* SugarWiki/AwesomeMusic: Aside from DannyElfman's title theme, the use of Harry Belafonte, including "Day-O", which is also a SugarWiki/{{Funny Moment|s}}.
* DesignStudentsOrgasm: This happens to the house at one point thanks to the Deetzes.
* EarWorm: The title theme by DannyElfman; wicked-cool, but hard to forget.
* EveryoneIsJesusInPurgatory: It's possible to interpret Betelgeuse/Beetlejuice as {{Satan}} himself. Besides having a name that looks similar to the Biblical "Beelzebub" (literally, "Lord of the Flies"), Beetlejuice is also given an origin story that could have come straight out of ''Literature/ParadiseLost'': Juno, who according to this analogy would represent God (and in fact is named after the queen-goddess of Roman mythology) mentions that Beetlejuice was once her assistant but had parted ways with her because he thought he could be a better exorcist. And it's not hard to imagine that Beetlejuice's threatened marriage to Lydia would not only make her his wife, but cost her her soul as well.
* FanficFuel: Just who was Betelgeuse before he died?
* FunnyAneurysmMoment: Sylvia Sidney plays a smoking ghost with a hole in her throat which emits smoke. Sidney died from throat cancer in New York City - at the age of 88.
* HarsherInHindsight: The film as a whole, with its humorous focus on death, was written by two screenwriters who died in their 40s.
* HilariousInHindsight: The original concept of Beetlejuice being a shape-shifting reptilian demon. One of the insults used against Ghost of ''Radio/TrueCapitalist'' is that he's a reptilian shape-shifter.
** Just like in this film, Michael Keaton had to wear similar eye makeup in the Batman films. The hilarious part comes in ''Film/BatmanReturns'' when Batman unmasks in front of Catwoman...
** Betelgeuse wore a wedding outfit that's similar to ComicBook/TheJoker's costume. Ohoho...
** In this film Creator/MichaelKeaton and Geena Davis are enemies, but a few years later they played lovers on opposite side of the political spectrum in 1994's ''Speechless'' (which also co-starred the late ChristopherReeve, of ''Superman'' fame, as a rival to former Batman actor Keaton).
** Lydia's reference to Delia "sleeping with Prince Valium tonight" becomes this when you consider an actual character by that name appeared in ''Film/{{Spaceballs}}'' (and after seeing him you can understand why Delia would be rendered unconscious by spending a night with him). This might actually be a ShoutOut, since ''Film/{{Spaceballs}}'' came out a year before ''Film/{{Beetlejuice}}''--but since both movies would have been in production very close together if not overlapping, it's more likely a hilarious incredible coincidence.
* IAmNotShazam: Due to the two being homonyms, people make the mistake of thinking the character is named Beetlejuice as well, rather than Betelgeuse.
** His name ''is'' Beetlejuice. He is forced to write it as a homonym for the same reason he cannot say or tell people his name; it's part of his exile.
** His name is officially "Beetlejuice" in the animated series - hence Lydia calling him "BJ."
** The Maitlands have difficulty summoning him at first as they are unfamiliar with astronomy and/or Arabic, pronouncing [[https://en.wikipedia.org/wiki/Betelgeuse "Betelgeuse"]] as "Bait All Guys."
*** Additionally, despite the poster, the film credits make it clear that the title is Beetle Juice, not Beetlejuice.
* MemeticMolester: Betelgeuse, particularly in light of his fixation on the teenage Lydia.
* MemeticMutation: "I'm the ghost with the most, babe."
** "Go ahead, make my millennium."
** To a much lesser extent: "My whole life is a dark room. One. Big. Dark. Room."
* OlderThanTheyThink: The Website/{{Cracked}} website may believe that the film's plot is borrowed from the ''Series/AmazingStories'' episode "[[https://www.youtube.com/watch?v=XXXE_nz-ZMo Boo!]]", but both of them were actually taken from the 1937 film, ''Film/{{Topper}}''.
* SomeAnvilsNeedToBeDropped: Considering how many people commit suicide? "Enjoy your life while you have it!" is a '''''damned important message.'''''
* {{Squick}}: Betelgeuse's fixation on Lydia. Unlike in the TV show, where they share an affectionate friendship, here the latter is clearly disgusted with the former (and her age makes him a potential pedophile to boot).
* TrueArtIsIncomprehensible: Delia's sculptures.
** Much of the film itself, to an extent.
* UncannyValley: Most of the film's stop motion effects fall under this to a rather serious extent, though considering the themes and tone of the film, it's fitting.
* {{Wangst}}. Lydia's suicide note is a little over-the-top.
--> ''"I am...alone. ''(Scraps, starts over)'' I am... utterly... alone. By the time... you read this... I will be gone... having jumped ''(scratches out jumped)'' having... ''plummeted...'' off... the Winter River Bridge."''
** Lydia's whole role in the film is a deliberate {{invo|kedTrope}}cation of this. The Maitlands (and even Betelgeuse himself) essentially talk her out of this attitude, and by the end she's a changed girl.
* WhatDoYouMeanItsNotForKids: Despite the PG rating, the film is loaded with adult themes such as death and sex (bear in mind that this film came out well ''after'' the PG-13 rating was introduced). Scenes that stand out in particular include Betelgeuse visiting a whorehouse and making a PrecisionFStrike - while honking his crotch, no less.

[[folder:The Animated Series]]

* AccidentalInnuendo: Lydia nicknaming Beetlejuice "BJ."
* CargoShip: In "Doomie's Romance," CoolCar Doomie falls in love with Mayor Maynot's adorable pink convertible, whom he names Pinky.
* FanficFuel: Without the FramingDevice of the film, how exactly ''did'' Beetlejuice and Lydia meet? And what became of their friendship after the end of the series?
* GhostShipping: Lydia and Beetlejuice.
* HilariousInHindsight: When Claire Brewster loses an election for class president in the episode "Running Scared," she immediately demands a recount.
* InNameOnly: Due to the [[AlternateContinuity different premise]], Lydia and Beetlejuice are friends now, and the Maitlands and Juno are nonexistent. Lydia is also several years younger than the movie version.
* TheScrappy: Claire Brewster for being an AlphaBitch and always insulting Lydia and her friends.
** Not many fans care for Beetlejuice's sickeningly sweet brother Donny, either.
* {{Squick}}: You think Beetlejuice's crush on Lydia is creepy? At least BJ is relatively human - in the episode "Pest O' The West", Lydia gets the unwanted attentions of an ''anthropomorphic bull ghost who wants to marry her''. Beetlejuice even sees what Lydia's future will be like if he doesn't go back to rescue her... [[NauseaFuel Yikes.]]
** If that wasn't bad enough, in his vision, there's little baby heifers running about all over the place. ''Ew...''
* TheyChangedItNowItSucks: Usually averted with the cartoon itself, as even die-hard fans of the film often find it amusing if nothing else. However, most fans agree that the spinoff book series is pretty bad, with flat writing and very out-of-character behavior for the stars.
* TheWoobie: Percy the Cat in "Bewitched, Bothered, & Beetlejuiced."
