* AlternateCharacterInterpretation: When Lydia tells Betelgeuse she wants to die, he might seem actually concerned for her. He keeps Lydia from leaving the house, possibly intending to talk her out of it (although he is manipulating her at the same time). Alternatively, his reaction could also mean, "But okay, if that's what you want, let me out and I'll help you do it."
-->'''Betelgeuse:''' You know, you look like somebody I can relate to. Maybe you could help me get out of here, you know, because I got to tell you, this dead thing... it's just too creepy. See, here's my problem. I got these friends I said I'd meet, and it's the kind of thing where I have to be there in person, so could you help me get out of here?
-->'''Lydia:''' I want to get in.\\
'''Betelgeuse:''' ''(genuinely surprised)'' Why? ''(pause)'' You know, hey, you probably got your reasons. I can't do anything from here. If you could get me out, then maybe we could talk or something.
* {{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 surely doesn't solve problems. SuicideIsShameful, and even a "natural" death is a cast-iron pain in the ass.
* SugarWiki/AwesomeMusic: Aside from Creator/DannyElfman's title theme, the use of Harry Belafonte, including "Day-O", which is also a SugarWiki/{{Funny Moment|s}}.
** "Jump in the line," used at the very end to great effect. Chances are you'll be tapping your foot to the tune.
* ChaoticNeutral: Beetlejuice himself falls under this trope. He's dangerously unpredictable, and though he's willing to help others, his idea of "helping" often involves endangering lives or conning them in some way.
* DesignStudentsOrgasm: This happens to the house at one point thanks to the Deetzes.
* EarWorm: The title theme by Creator/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 have not only made her his wife, but very possibly would also have cost her her soul.
* FanficFuel: Just who was Betelgeuse before he died?
* {{Fanon}}: Lydia's birth mother is never mentioned in the film. A large portion of the fanbase is convinced that she died when Lydia was very young, and that this fact heavily contributes to Lydia's fascination with death.
* FunnyAneurysmMoment[=/=]HarsherInHindsight:
** 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.
** Snake!Beetlejuice knocking Otho down the stairs is a little hard to watch now, knowing that his actor Glenn Shadix died of head trauma following a fall.
* HilariousInHindsight:
** The original concept of Betelgeuse was 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, Creator/MichaelKeaton 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's wedding outfit is somewhat similar to ComicBook/TheJoker's costume. Ohoho...
** In this film Creator/MichaelKeaton and Creator/GeenaDavis are enemies, but a few years later they played lovers on opposite sides of the political spectrum in 1994's ''Speechless'' (which also co-starred the late Creator/ChristopherReeve, of ''Film/{{Superman}}'' fame, as a rival to former ''Batman'' actor Keaton).
* IAmNotShazam: Due to the two being homonyms, people make the mistake of thinking the character is named Beetlejuice as well, rather than Betelgeuse. The fact that his name ''is'' Beetlejuice in the AnimatedAdaptation doesn't help.
** 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", "beetle guy", and "Beetle Meyer".
** 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."
** "I, myself, am strange and unusual."
** "Hi, how are ya?"
** "It's showtime!"
* 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 rather important message.
* SpaceWhaleAesop: Barbara dissuades Lydia from committing suicide by telling her that things don't get any easier after death. The aesop seems to be that an untimely death will land you in a frustrating afterlife bureaucracy.
* {{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. Her VagueAge makes him a potential pedophile to boot; at the very least, he's definitely an {{ephebophile}}.
* 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 ([[ValuesDissonance bear in mind that this film came out well ''after'' the PG-13 rating was introduced]]), along with some bloodless but still gruesome implied mutilation. Scenes that stand out in particular include Adam's temporary decapitation and a woman in the afterlife who was cut in half in [[SawAWomanInHalf a parlor trick gone wrong]], along with Betelgeuse visiting a whorehouse and making a PrecisionFStrike - [[ArsonMurderAndJayWalking while honking his crotch, no less.]]

[[folder:The Animated Series]]

* AccidentalInnuendo: Lydia nicknaming Beetlejuice "BJ" and the car "Doomie."
* 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 the election for class president in the episode "Running Scared," she immediately demands a recount. This became funnier in light of the 2000 Presidential election, when a whole lot of hubbub erupted over how close the votes were in Florida, with Gore's campaign calling for a manual recount.
** The RunningGag in "Robbin Juice of Sherweird Forest," in which there are repeated comments about Beej's {{wanted poster}}s, may remind modern viewers of the similar gag in ''Disney/{{Tangled}}''.
* InNameOnly: Due to the [[AlternateContinuity different premise]], Lydia and Beetlejuice are friends now, and the Maitlands and Juno are nonexistent. Lydia is also younger than the movie version.
* JerkassWoobie: Beetlejuice himself, in "It's a Wonderful Afterlife." It's not hard to understand why most of his neighbors would be enjoying much better circumstances without him on hand to wreak havoc (and keep them humble in the process), and he does begin the episode by complaining about everything and being generally annoying. Nevertheless, you can't help but feel sorry for the guy when he feels like nobody wants him around.
* 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.
** Prince Vince, with his overly dramatic tendencies, is seen this way by a portion of the viewers as well.
* ShipTease: Frequently between the two leads, despite the age difference and the gender-flipped BoyMeetsGhoul.
* {{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 No wonder he starts screaming.]]
** If that wasn't bad enough, in his vision, there's little baby heifers running about all over the place.
* TastesLikeDiabetes: Neither-neither Land invokes this deliberately.
* TheWoobie: Percy the Cat in "Bewitched, Bothered, & Beetlejuiced."

[[folder:Other Media]]
* ShipTease: The comic books hint a fair bit at gender-flipped BoyMeetsGhoul, much as the cartoon does.
** The NES game (based on the film) has Betelgeuse outright describing Lydia as "[[OneTrueLove my true love]]." The Game Boy game (based on the cartoon) is also full of ship tease, particularly in the many {{affectionate nickname}}s Beetlejuice has for Lydia.
** The spin-off novel series has an installment, ''Lydia's Scream Date'', whose plot centers entirely around BJ being a CrazyJealousGuy over Lydia possibly going to a school dance with a living boy.
* TheyChangedItNowItSucks: Usually averted with the cartoon, as even die-hard fans of the film often find it amusing if nothing else. Fans of the cartoon usually at least get a kick out of the comic books as well. However, even those who prefer the cartoon over the film tend to agree that the spin-off novel series is pretty bad, with flat writing and very OOC behavior for the characters.
