-->-- [[https://youtu.be/m9We2XsVZfc The theme song]], sung by Ray Parker Jr.

An enduringly popular SciFiHorror[=/=]UrbanFantasy[=/=]{{Comedy}} franchise in which MadScience takes on occult terror and wins, while [[HilarityEnsues hilarity (usually) ensues]].

The setting[[note]]except for some {{Fan Film}}s, a few episodes of the two animated series and ''Film/GhostbustersAfterlife''[[/note]] is modern day UsefulNotes/NewYorkCity, which has become overrun with supernatural creatures of every description. Some ghosts are mere annoyances or even benign, but all too many of them are dangerous, and a few are bent on causing TheEndOfTheWorldAsWeKnowIt. There's only one force that can stop them: A RagtagBunchOfMisfits who protect humanity with [[MadScientist experimental and dangerous high-tech weaponry]] -- and entertain generations of viewers with their [[CloudCuckoolander quirky]] [[BunnyEarsLawyer personalities]] and [[DeadpanSnarker witty]] [[CasualDangerDialogue dialogue]].

The franchise started with ''Film/{{Ghostbusters 1984}}'', a film starring Creator/BillMurray, Creator/DanAykroyd, Creator/HaroldRamis and Creator/ErnieHudson, and co-starring Creator/SigourneyWeaver, Creator/RickMoranis, and Creator/AnniePotts; Aykroyd and Ramis also wrote the script. It was a smash hit which led to a sequel, ''[[NumberedSequels Ghostbusters II]]'', in 1989. Both films were directed by Creator/IvanReitman.

The films produced a popular AnimatedAdaptation -- ''WesternAnimation/TheRealGhostbusters'' in 1986, which had its own SpinOff, ''WesternAnimation/ExtremeGhostbusters'' in 1997. As a rule of thumb, they aren't in continuity with the movies and the later video game (one episode of the cartoon even had them [[RecursiveCanon watching the original movie]]) but are otherwise based on the same story and [[MagicAIsMagicA internal principles]] that the movies introduced.

There was also TheRolePlayingGame developed by West End Games in 1986; set after the first movie, the players were cast as owners[=/=]employees of a ''Ghostbusters'' franchise in their local community. In addition to ghosts, adventure hooks could feature encounters with other paranormal creatures and incidents, including vampires, aliens, and time-travelers. A revised version of the game, ''Ghostbusters International'', was published in 1989 following the release of ''Ghostbusters II''. It was eventually named as one of "The Millennium's Most Underrated Games" by ''Pyramid'' magazine.

A theme park show, ''Theatre/GhostbustersSpooktacular'' was yet another product of the franchise, being one of the opening day attractions at [[Ride/UniversalStudios Universal Studios Florida]] in 1990. However, it was later quietly closed in 1996. Along with the attraction, the Ghostbusters used to be involved in a lot of the park's street entertainment, most notably in an IntercontinuityCrossover show where the team clashed against Film/{{Beetlejuice}}. The latter show continued to operate until 2005, when Universal gave up the theme park license for the series.

The franchise had numerous video games made for it. Practically every video game system that existed in the mid-eighties had an adaptation of the first movie created for it, in addition to at least one adaptation of the second movie, an arcade game and a game with an original story created in 1990 for the Sega Genesis. In 2009, a [[VideoGame/GhostbustersTheVideoGame video game adaptation]] was released, written and performed by the original cast, which acts as a third story. Two years after the second movie, the Ghostbusters are doing well. The new mayor rode into office on pro-Ghostbusting legislation: New York directly pays the Ghostbusters for doing their job, and [[HeroInsurance insures all of their collateral damage]]. In addition, their research on paranormal activity has given them enough cash to develop new technology, which allows them to hire a young intern (the player character) to test it out for them. However, a Gozer exhibit at the local museum triggers a reawakening of the forces unleashed in the first movie...

Because Creator/DanAykroyd and Creator/HaroldRamis were a key part of developing the story, they have stated that this game is in the same {{continuity}} as the movies. Interestingly, there are still some variations to the plot that occur with three distinct versions: a "Realistic" version for the Platform/PlayStation3, Platform/{{Xbox 360}} and [[Platform/MicrosoftWindows Windows]] (which was remastered for the Platform/PlayStation4, Platform/{{Xbox One}} and Platform/NintendoSwitch in 2019); a "Stylistic" version for the Platform/PlayStation2, [[Platform/PlayStationPortable PSP]] and Platform/{{Wii}}; and a version for Platform/NintendoDS that has totally different gameplay (and doesn't even have the rookie). The console games were very well received and applauded for being a unique and dynamic gaming experience. Tropes relating specifically to the Video Game (especially video game tropes) should go on the page for the game.

There was also a comic book series by long-defunct NOW Comics which used the animated series' art style but had its own story lines. Creator/IDWPublishing, after a couple of miniseries, is now publishing an ongoing comic series picking up a few years after the second movie.

Talk about a third film [[DevelopmentHell persisted for decades]], and seemingly ended with the death of Harold Ramis in February 2014. ''Film/{{Ghostbusters|2016}}'', a ContinuityReboot with female leads, was announced in October; it was released on July 22, 2016. In December of that same year, the franchise received its second theme park attraction spin-off, ''Ghostbusters: Battle for New York'', a LightGunGame ride that opened with the Motiongate UsefulNotes/{{Dubai}} theme park.

After having been hinted at by Dan Aykroyd a couple of months prior, it was announced in January 2019 that Creator/JasonReitman would be directing a sequel to the first two films entitled ''Film/GhostbustersAfterlife''. The film stars Creator/CarrieCoon, Creator/MckennaGrace, Creator/FinnWolfhard, and Creator/PaulRudd, with most of the original cast appearing in some capacity. It was the final ''Ghostbusters'' project to involve Ivan Reitman before his death in February 2022.

For its 35th anniversary, the series made a comeback to the Ride/UniversalStudios parks, in the form of a haunted house at Theatre/HalloweenHorrorNights.

A [[http://ghostbustersnews.com/2016/06/20/sony-announces-new-ghostbusters-cartoon-show/ new animated series,]] ''Ghostbusters: Ecto Force'', is also in development. An [[http://www.hollywoodreporter.com/heat-vision/ghostbusters-animated-movie-snares-clash-862537 animated film,]] to be directed by Fletcher Moules (best known for his ''VideoGame/ClashOfClans'' commercials), is also planned, and ''Ecto Force'' (which was originally scheduled for 2018) has been put on hold until it's completed.

A new ''Ghostbusters'' film (later titled ''Film/GhostbustersFrozenEmpire'') was [[https://deadline.com/2022/04/ghostbusters-5-new-movie-1235009684/ teased]] at [=CinemaCon=] 2022. On Ghostbusters Day of that same year, Jason Reitman and ''Afterlife'' co-writer Gil Kenan [[https://variety.com/2022/film/news/ghostbusters-animated-film-afterlife-sequel-new-york-city-1235288974/ confirmed]] the sequel would return to New York City. The pair also confirmed that they would collaborate with Creator/SonyPicturesAnimation on both an [[https://variety.com/2022/film/news/ghostbusters-animated-film-afterlife-sequel-new-york-city-1235288974/ animated film]] to be directed by Creator/{{Titmouse}} founder Chris Prynoski and ''WesternAnimation/HotelTransylvaniaTransformania'' co-director Jennifer Kluska AND an [[https://variety.com/2022/tv/news/ghostbusters-animated-series-netflix-jason-reitman-gil-kenan-1235285985/ animated series]] for Creator/{{Netflix}}. It is unknown if these projects are related to the ones mentioned above.

!!Not part of the official franchise, but still worth mentioning:
* ''Series/TheGhostBusters''. A live action Creator/{{Filmation}} series from TheSeventies that was so obscure that the creators of the original movie weren't aware of it until after they started production. Other than [[SimilarlyNamedWorks the title]] and the basic premise, it has no relation to the films and their spinoffs.
* ''WesternAnimation/FilmationsGhostbusters''. An animated SequelSeries to the show above. It owes its existence to the success of the films.
* TheRealSpoofbusters, a trope for StockParodies of this franchise.
!!Tropes pertaining to the franchise as a whole:
* EightiesHair:
** ''Ghostbusters'': People with pink, blue, and big hair are all seen milling about through New York City in various scenes, particularly at the climax.
** ''Ghostbusters 2'': The saleswoman at the Orrefor's fine crystal store seen in the montage.
* AdmiringTheAbomination: Ray and Egon are regularly enthralled or intellectually intrigued by the pandimensional beings they deal with, which contrasts with the deadpan or mundane approaches from Peter and Winston.
* AerithAndBob:
** To some degree. Our main characters include Winston, Peter, Ray, Louis, Dana, Janine... and Egon. While Egon is an actual name of Teutonic origin (meaning "formidable" or "mighty with a sword"), it sounds a little bit out of place surrounded by more common names.
** The cast has this, too! Ernie, Bill, Dan, Rick, Harold, Annie... and ''Sigourney''.
* AlwaysChaoticEvil: Apparently all spirits capable of interacting with the physical plane are malicious or at least mischievous. The least harmful ghosts the 'busters encounter are only benign until someone gets their attention, like the library ghost. This makes indiscriminately locking them up in the containment system more justifiable.
* AmbiguouslyJewish: Egon, Janine and Louis, who all have Jewish-sounding surnames, and Egon in particular has a hairstyle that was common among Jewish men in the '80s. The cartoon runs with this, giving Egon a JewishMother who feeds the boys a homemade FoulMedicine when they get sick.
* AmmunitionBackpack: The Proton Packs probably count, since all the particle accelerating takes place in the Pack.
* AuthorAppeal: Aykroyd's fascination with ghosts and the supernatural is well known. Thus leading to the dream sequence …
%%* AutobotsRockOut!: Their theme music alone is good enough for this trope.
%%* AwesomeBackpack: The proton packs.
* BadBadActing: In the Ghostbusters' TV ads. In the first film, Peter, Ray and especially Egon read their lines in a very stilted manner. In the second film, Janine and Louis do this in their new commercials. In the same in-universe ad, Egon looks down before stepping forward and back, looking for his mark.
* BadassBoast:
** "Who you gonna call?"
** "We came, we saw, we kicked its ass!"
** In the first movie, when they confront Gozer: "Let's show this prehistoric bitch how we do things downtown!"
** The franchise's motto is used for this in the second movie during the courtroom scene: "Sometimes, [[PrecisionFStrike shit]] happens, someone has to deal with it, and who you gonna call?"
** They get two after busting the Scoleri brothers.
--->'''Ray:''' Two in the box!\\
'''Egon:''' Ready to go!\\
'''Peter:''' We be fast...\\
'''All:''' And ''they be slow!''
** Also in the second film, after exiting the courtroom in triumph: "We're the best, we're the beautiful, we're the ''only''... Ghostbusters!"
%%* BadassCrew: A crew of {{Badass Bookworm}}s.
* BeautyIsNeverTarnished:
** Played straight: Dana Barrett. Despite being possessed in the first movie and dealing with empathic slime in the second, the worst she gets is a little dusty and her hair mussed.
** Played with: Peter Venkman. Venkman gets slimed ''once'' very lightly, and is the only Ghostbuster to end up not covered in ectoplasmic toasted marshmallow when Stay Puft is defeated. Winston, Egon, and Ray all get CoveredInGunge repeatedly throughout both movies.[[note]]It's a meta reason in Venkman's case. Bill Murray is the biggest name in both films, so his face doesn't get covered up, nor does he have to deal with dignity-diminishing effects.[[/note]]
* BerserkButton: Slimer really doesn't take well to being called ugly...
* BigApplesauce: Considered one of the quintessential New York City films. The last line of the first film summarizes it perfectly:
-->'''Winston:''' I LOVE THIS TOWN!!!
%%* BigBad:
%%** Gozer the Traveler in the first movie
%%** Vigo the Carpathian in the second.
%%** [[spoiler:Ivo Shandor]] in the video game.
%%** [[spoiler:Rowan North]] in the ContinuityReboot.
%%** [[spoiler:Gozer returns]] in ''Afterlife.''
* BigDamnHeroes: In the second movie, the Ghostbusters arriving via skylight to stop Oscar being turned into a new host body for Vigo the Carpathian.
* BigEater: Uh, Slimer. (Called "the Green Ghost" in the first movie and was officially named "Peanut", but given the name "Slimer" in the cartoon and the credits of the second.) The cast thought of him as the ghost of Creator/JohnBelushi. He's seen eating hotel food in his first scene, then later he eats a whole lot of hot dogs.
* {{Bowdlerise}}: In reverse. In the '80s, commercials for the first movie ended with Venkman saying, "We came, we saw, we kicked its [[CurseCutShort a--" cut to logo]]. Now on just about any cable channel allows him to say 'ass'. Trailers for the 30th Anniversary keep this, certainly as an homage to the earlier censoring.
* BuiltWithLEGO:
** In 2014, six years after ''LEGO VideoGame/RockBand'' [[https://www.youtube.com/watch?v=7tl8B4Mb7nE featured the theme song]], an official LEGO set was approved via LEGO Cusoo, featuring Egon, Venkman, Ray, Winston, the Ecto-1, and Slimer.
** The Series also features in ''VideoGame/LegoDimensions'', with the Level Pack including a condensed version of the first film as a playable level- although in this case, as a consequence of [[BigBad Lord Vortech's]] plans to conquer the multiverse, [[Franchise/{{Superman}} General Zod]] is the villain who's wreaking havoc.
* BunnyEarsLawyer: Ray and especially Peter, who both have [=Ph.D=]s, in Physics and Parapsychology/Psychology respectively. Ray is more childlike, but Peter is full-on childish. Both of them are, despite Peter's professions to the contrary, fairly unprofessional.
* ButtMonkey: Several.
** Louis Tully, who has doors shut in his face, doors locking him out, and other comical misfortune.
%%** Ray Stantz, because he's a goof.
** Walter Peck, hereafter known as "dickless".
** The student involved in the ESP test that was repeatedly shocked.
* TheCameo: Creator/DanAykroyd briefly appears as Ray Stantz in the 1995 ''Film/{{Casper}}'' film.
* CasualDangerDialogue: Egon is a master of this, usually as a way of flatly commenting that he's scared out of his mind ''despite'' being overly calm and talking plainly.
-->'''Venkman''': Okay, Ray's gone bye-bye. Egon, what've you got left?\\
'''Spengler''': Sorry, Venkman, but I'm terrified beyond the capacity for rational thought.
** He manages Casual Danger ''Laughter'' in 2. Ray and Peter laugh nervously while waiting for the Scolari Brothers to strike, and Egon chimes in with a monotone "[[FlatJoy Ha. Ha ha.]]"
* ChuckCunninghamSyndrome: Despite being a major character in both movies, Dana Barrett almost never shows up in spin-offs, being absent from both ''WesternAnimation/TheRealGhostbusters'', ''VideoGame/GhostbustersTheVideoGame'' and the IDW ''ComicBook/{{Ghostbusters}}'' comic book. She may get a brief mention, if she's lucky.
* CompleteImmortality: Almost all ghosts that are not at least a Class 7 are this, which is why they get trapped and sent into the containment unit.
* {{Crossover}}: The series has been involved in several, particularly in but not exclusive to the [[ComicBook/GhostbustersIDW IDW comics]]:
** Numerous internal crossovers with the various incarnations of the team (original version, [[WesternAnimation/TheRealGhostbusters Real]], and [[Film/Ghostbusters2016 Answer the Call]]).
** ''Franchise/TeenageMutantNinjaTurtles'', at least twice.
** ''Film/{{Beetlejuice}}'' by way of a live show.
** ''Franchise/{{Transformers}}'': The Ecto-1 has been made into a ''Transformers'' toy from the ''ComicBook/TransformersGhostbusters'' series.
* DangerousForbiddenTechnique: Early on in the first movie, Egon tells the others not to "cross the streams" (i.e. make the streams from the proton packs touch), since "it would be bad", but later, they have to do it anyway.
* DestructiveSaviour: The Ghostbusters are very effective at capturing ghosts, but their primary weapons, the proton packs, are terribly inaccurate and burn through whatever they hit when they miss (which is often). That's not even getting into the larger threats, which tend to end up leveling city blocks before the Ghostbusters stop them. Gozer blew up the top few floors of a high rise building as a consequence of stopping her.
-->'''Venkman:''' [[LetsSplitUpGang Yeah]]... we can do more damage that way.
* DidYouJustFlipOffCthulhu: To the point where insulting the villains, despite them being powerful entities, is standard operating procedure... right before arming the proton packs.
* DidYouJustPunchOutCthulhu:
** Oh yes. Gozer the Gozerian gets beaten by [[ForbiddenChekhovsGun crossing the streams]]. They also fight what are expressly described as "Deity" ghosts in the game.
** They deal with Franchise/{{Cthulhu|Mythos}} himself over in the animated series, with Egon noting that Cthulhu made Gozer look like "Little Mary Sunshine".
* DopeSlap: At the beginning of the film, Peter slaps Ray when Ray interrupts his "moment" with a beautiful young test subject. Ray gets him back later, when Peter doesn't understand the significance of the blueprints of Dana's building.
* EccentricExterminator: The Ghostbusters are an odd bunch of mad scientists.
* ExtranormalPrison: Their containment unit holds all the ghosts they capture.
* FanFilm: Has inspired a whole slew of fan films based on the idea of Ghostbusters becoming a franchise business and organized in other cities. This includes ''[[Franchise/ANightmareOnElmStreet Freddy]] Vs. Ghostbusters'', ''The UsefulNotes/{{Denver}} Ghostbusters'' and ''WebVideo/GhostbustersSLC''.
* FantasticReligiousWeirdness: The church does not want to take an official position on the paranormal events happening in New York in either movie, though in the first movie, multiple religious figures are seen praying: Priests, Nuns, Rabbis, and an Imam.
* FantasticScience: Two of the three original characters, Ray and Egon, are legitimate paranormal researchers that channel their knowledge into the business of "paranormal investigations and eliminations." Peter for his part is both a psychologist and parapsychologist, so he contributes the human relations and OnlySaneMan elements. WordOfGod is that Egon and Ray are legitimate practitioners of their field (albeit Egon is far better at it) while Peter didn't believe in the supernatural until he was confronted with it.
* FirstNameBasis: The Mayor and the Archbishop of New York have this with each other. The Mayor is taken aback when Peter tries to invoke this with him as well.
* ForbiddenChekhovsGun: Crossing the streams. They are warned never to do it, and it becomes their FinishingMove.
* {{Foreshadowing}}:
** In the "eggs frying on the counter" scene, among Dana's groceries can be seen a bag of "Mr. Stay Puft" marshmallows.
** There's an unoccupied fourth seat at the table where the Ghostbusters eat what would've been their last meals before going out of business, hinting at the eventual addition of a fourth member.
* ForScience: Generally the reason why Egon runs oddball experiments.
-->'''Peter:''' Egon, this reminds me of the [[NoodleIncident time you tried to drill a hole through your head]]. Remember that?\\
'''Egon:''' [[ThrowItIn That would have worked if you hadn't stopped me.]]
%%%* FourTemperamentEnsemble: Ray is sanguine, Peter is choleric, Egon is melancholic, Winston is phlegmatic.
%%%* FreudianTrio: Peter as TheKirk, Egon as TheSpock, and Ray as TheMcCoy.
* FunnyBackgroundEvent:
** After blowing up the poor housemaid's cart, while they stand around talking, you can see her trying to ''spritz'' out the fires they started with a bottle of cleaner.
** During the cutscenes in the video game, The Rookie can be seen reacting to the situations in humorous ways, especially when Mr. Stay Puft first appears.
** During the KitschyLocalCommercial, you can see Egon continuously looking down at the marks he's supposed to stand on. This was an actual mistake made by Harold Ramis, who agreed to [[ThrowItIn keep doing it for subsequent takes when everyone agreed it fit Egon's character.]]
** When Peter is informing the hotel manager about the cost of their operation, Egon is subtly flashing him hand signals about how much to charge; this can usually only be seen in widescreen presentations, as other cuts tend to crop out Egon from the frame.
** When they're investigating the library ghost, Ray freezes and says "Listen! Do you smell something?" Behind him, Peter draws back, then rolls his eyes and shakes his head.
** During the "Ghost Fever Grips New York" montage, a bearded bystander in blue notices the man-on-the-street reporter talking about the Ghostbusters and sways for a few moments before making a hand sign and moving on.
* GateGuardian: Zuul (who looks like a large demonic dog) is the Gatekeeper of the dimensional portal that Gozer the Gozerian arrives through. Its (her?) counterpart, Vinz Clortho, The Keymaster, also looks like a giant demon dog.
* GhastlyGhost: The various ghosts fought by the team are typically very destructive, and can vary from simply malevolent spirits to monstrous and aggressive entities to borderline Eldritch Abominations, depending on their individual power and origin. A given ghost's rampage may be limited to annoying pranks, or it may involve violent mayhem or the very real threat of a localized apocalypse.
%%* GhostInvasion: The entire premise of the franchise is based around this.
%%* GhostlyGoals: Usually of the highly destructive variety.
* HarmlessVillain: Vigo becomes this in the ''Ghostbusters'' video game. The best he can do is insult you and try and make you feel uncomfortable.
* HerosClassicCar: The Ecto-1, a 1959 Cadillac Miller-Meteor ambulance, refurbished and tricked out with Science!
* InevitablyBrokenRule: Egon strongly cautions to never "cross the streams" while firing their power-packs, as it could potentially kill them all and cause massive destruction. However, at the end of the movie, they do it anyway [[spoiler:in order to defeat the BigBad. They survive]].
* InsignificantAnniversary: The Ghostbusters, who had to mortage the childhood home of their resident NiceGuy Ray to even afford the decrepit fire-station that housed their flegeling business, sadly toasted "to our first and '''only''' customer" in a month and imminent bankruptcy with takeout noodles and beer... and then the usually grumpy secretary downstairs ''happily'' shouted ''"WE GOT ONE!!"'' as the phone rang downstairs calling from a posh hotel plagued by a green ectoplasmic eating machine... and three heroes began their journey proper that night.
* JerkWithAHeartOfGold: ''Venkman''.
-->'''Venkman''': "Type somethin', will ya? We're payin' ya for this stuff. And don't stare at me, ya got the bug-eyes…" (pauses) "Janine, sorry about the bug-eyes thing, I'll be in my office."
* JustInTime: As the Busters realize they are broke and about to go out of business, Janine gets a phone call.
-->'''Janine:''' Hello, Ghostbusters. Yes, of course they're serious. You do? You ''have?... '''WE GOT ONE!'''''
* {{Leitmotif}}: The Ghostbusters have a theme tune when they're going around the city outside of work.
* LicensedPinballTables:
** For a franchise ripe with licensing potential, it took 30 years before an official {{Pinball}} table was released. And even then, ''VideoGame/GhostbustersPinball'' was made by digitally retheming an existing game, Creator/{{Gottlieb}}'s ''Pinball/HauntedHouse''.
** There are also rumors that ''Pinball/ThePartyZone'' was intended to be a ''Ghostbusters'' pinball game, but was changed when a licensing deal could not be reached.
** It took until 2016 for a real licensed pinball table to be released, Stern's ''{{Pinball/Ghostbusters}}''.
* LovableCoward: For all his charm and bravado, Peter Venkman is not the bravest of men. With a few exceptions any acts of heroism on his part will usually be very very reluctant ones. That said, he will step up to the plate if necessary; he just won't be very happy about it.
* MadScientist: Mostly Egon, but a little bit in Ray as well. Capitalism and a general sense of the good of mankind steers this towards positive and constructive directions.
-->'''Peter:''' Egon, this reminds me of the [[NoodleIncident time you tried to drill a hole through your head]]. Remember that?\\
'''Egon:''' [[ThrowItIn That would have worked if you hadn't stopped me.]]
** At the end of the first movie, after rescuing Louis, he asks him if he'd like to donate a sample of his brain tissue, which Louis, still dazed, agrees to.
* MagicVersusScience: Ghosts and gods vs. scientists with nuclear accelerators; the scientists win.
* MagneticPlotDevice:
** The first two films show that the only reason New York appears to be swimming in ghosts is because something is empowering them. The 2009 video game links the two by explaining that Ivo Shandor, the Gozer cultist leader who designed Dana Barrett's high-rise apartment building to give Gozer a doorway into our world, also developed the "mood slime" that Viggo utilized when his painting was shipped to the MOMA five years after the events of the first film
-->'''Ray''': The whole building is a huge super-conductive antenna that was designed and built expressly for the purpose of pulling in and concentrating spiritual turbulence. Your girlfriend, Pete, lives in the corner penthouse of Spook Central.
** Shandor is revealed also developed a backup portal in Summerville for Gozer to use in ''Ghost Busters Afterlife''.
** "Frozen Empire" then cements the Firehouse that the Ghostbusters use became an supernatural attractor since their Containment Grid first shut down.
** In the reboot, the whole ''plot'' only happens because the film's BigBad Rowan North built a machine to amp up supernatural activity.
* MascotVillain: Slimer is a partial example. He starts off as a StarterVillain in the first movie, but by the time he became a true mascot in the animated adaptations he became the TeamPet and sidekick. A more fitting (in and out of universe) example is the [[AttackOfTheFiftyFootWhatever Stay-Puff Marshmallow Man]], or rather, Gozer the Gozerian, who took the form of the Stay-Puff Marshmallow Man in a bid to start TheEndOfTheWorldAsWeKnowIt.
* TheMerch: In-universe examples. In the first film's credits, there are kids waving Ghostbuster logo t-shirts. ''Ghostbusters II'' has the gang offer branded thermal mugs and balloons in their commercial.
* MonochromeApparition: Most of the human-esque ghosts are depicted in one colour.
* MugglesDoItBetter: the title characters are [[ScienceHero Science Heroes]] who take on ghosts and extraplanar creatures. Furthermore, they are able to because they are able to [[FantasticScience study them scientifically]] and develop effective weapons that are relatively easy to use.
* MundaneMadeAwesome: Part of the joke of the franchise is that dealing with supernatural entities like ghosts, otherworldly demons and Lovecraftian {{Eldritch Abomination}}s becomes, once the Ghostbusters have come along and applied a little practical science to the matter, basically a form of glorified pest control.
* NiceJobBreakingItHero: Ray gets this a lot.
** He chooses Gozer's destructive form as Stay Puft.
--->'''Peter:''' Did you choose anything?!\\
'''Egon:''' No.\\
'''Peter:''': Did you?!\\
'''Winston:''' My mind's a total blank.\\
'''Peter:''' ''I'' didn't choose anything! ''[{{Beat}}, then everybody looks at Ray]''
** Knocking out all the lights in New York in the sequel. Ray is quite the klutz.
** Later, when they're about to call the final battle a victory, he looks into the painting and [[spoiler:gets possessed by Vigo.]]
** Venkman's antagonism towards Peck spurs him to come back with a warrant, specifically to cause as much trouble as possible. The clash was probably going to happen anyway, but Peter makes [[ItsPersonal it a personal feud]].
* NightVisionGoggles: A slightly modified set of ''actual'' night vision goggles is made to be the "ecto goggles" and part of the Ghostbusting gear, supposedly allowing them to see ghosts who have turned themselves invisible. It's seen on everyone in the first movie, used memorably by Ray in the hotel and seen briefly a few times in the second movie. The game makes it into a major gameplay mechanic in tracking down ghosts.
* NonActionGuy: Rick Moranis' character, Louis. Though he does [[TookALevelInBadass take a level in badass]] in the second movie.
* NoodleIncident: Mentioned in the first film is that time Egon tried to drill a hole through his head. This is an actual procedure, called [[https://en.wikipedia.org/wiki/Trepanning trepanation]], which is sometimes claimed to confer psychic powers. "That would have worked if you hadn't stopped me." (This was allegedly a ThrowItIn by Murray which Ramis seamlessly responded to.)
* NotQuiteDead: Justified since this is a franchise about '''ghosts'''. Also notable in the account of Vigo's death.
-->'''Ray Stantz:''' He didn't die of old age, either. [[RasputinianDeath He was poisoned, stabbed, shot, hung, stretched, disemboweled, drawn and quartered.]]\\
'''Peter:''' [[MajorInjuryUnderreaction Ouch.]]\\
'''Ray:''' There was a prophecy. Just before his ''head'' died, his last words were "Death is but a door. Time is but a window. I'll be back."
* ObstructiveBureaucrat: The worst kind of nonbelievers.
** Walter Peck from the first movie ignores the very real paranormal phenomenon around him in favor of his insistence that it's all a scam. His actions in service of this belief directly trigger Gozer's arrival. Then he blames everyone but himself and has them arrested.
** Hardemeyer takes this role in the sequel. He has the Ghostbusters ''committed'' to avoid bad press for the mayor.
** Peck is back as the city official appointed as a liaison between the Ghostbusters and the mayor in the video game.
* OddlySmallOrganization: The scientific ghost-fighting security agency for the entire New York area is three (later four) men in an old firehouse. Franchise rights are briefly discussed but nothing ever comes of it in the films.
* OffTheShelfFX: Venkman's ghost-sniffer, also known as the "Bacharach Chemical Sniffer", which is used primarily for detecting gas leaks. This also carries over into the guys' HomemadeInventions (a kitchen colander with wires and things on it, for one).
** The ectoplasm was made from methylcellulose ether, a thickening agent used in processed foods.
** The "marshmallow" goo was actually shaving cream. More than 50 gallons was dumped on William Atherton, almost knocking him to the ground.
* OneWingedAngel: Ghosts who take human form as a disguise are usually provoked into taking monstrous forms.
* OurGhostsAreDifferent: In the series, "ghost" seems to be a catch-all term for incorporeal creatures, including both the spirits of the dead and extraplanar creatures that were never "alive" to begin with.
* ParanormalInvestigation: Although they're more like a decontamination crew than detectives or investigators.
* PhotoprotoneutronTorpedo: Proton packs, which are "positron colliders" (or sometimes "unlicensed nuclear accelerators") that shoot particles from "neutrona wands".
* PictorialLetterSubstitution: Sometimes, the "O" in the title is replaced with the main logo: a ghost under a "no" sign.
* PortalStatuePairs: Zuul and Vinz Klortho, two giant demon dog statues that guard the portal of Gozer; they can also come to life and attack/possess people.
* PunchClockHero: Pretty much all of the Ghostbusters, sans [[NightmareFetishist Ray]], became heroes to earn money. However, they [[CharacterDevelopment start to outgrow this a little.]]
* PunyHumans: Inverted in that ScienceHero mortals scientifically learned about the nature of the supernatural, ranging from simple ghosts to gods, develop practical and easy to use weapons against it and totally ''clean its clock''!
* RagtagBunchOfMisfits: The Ghostbusters themselves; a cynical scientist, a mad scientist, a goof scientist, and someone looking for a steady paycheck.
* ReasonableAuthorityFigure:
** Lenny the Mayor fills this role to some extent in the first two movies. He's a rather cynical politician whose public image and chances of re-election / further political office are never far from mind, and is reasonably skeptical of the claims of apocalyptic supernatural phenomena, but when suitably convinced of their claims ultimately proves to be a fairly staunch ally. However, it is suggested that between the first and second movies, he either had them publicly thrown under the bus, or didn't do much to stop it from happening.
-->'''Ray:''' First of all, Mr. Mayor, it's a great pleasure to see you again. And we'd like to say that [[FalseReassurance almost 50% of us voted for you in the last election]].\\
'''Mayor:''' I appreciate that.
** By the time of the game, he seems to have been replaced with a more straightforward example of this trope; the current mayor got elected on a pro-Ghostbuster platform, and now has the city [[HeroInsurance covering their collateral damage]].
* RedAlert: Of the "Emergency Squad Scramble" variety, the first time a call comes in.
* ReedRichardsIsUseless:
** Played with. On one hand the Ghostbusters ''do'' use their tech to make money for themselves, the game has established them as contractors to New York on the verge of franchising, and they obviously help people out with it, but the potential other uses for their tech goes ignored.[[note]]Though, given their tech is highly destructive and has no obvious application on anything other than ghosts, it's possible they [[CripplingOverspecialization designed their tech so specifically that there ''are'' no other potential uses]].[[/note]]
** In the cartoon, the Ghostbusters temporarily convert their gear to allow them to catch criminals for bounties, but the [[CripplingOverspecialization premise remains the same]].
%%* RentAZilla: The Stay Puft Marshmallow Man by the villains, and The Statue of Liberty by the heroes.
* RomanticismVersusEnlightenment: Standing out from a lot of the occult horror genre movies of its time, Ghostbusters is very pro-Enlightenment-esque. [[Creator/BobChipman MovieBob]] says it best in a Youtube episode of "Really That Good" on this movie [[https://www.youtube.com/watch?v=BPoILjs6BYI&feature=player_detailpage#t=1154 at the 19:14 mark]].
* SassySecretary: Janine "I've quit better jobs than this!" Melnitz, although it varies by production. In the first film, she is a no-nonsense girl who snaps at Peter while crushing on Egon. In the second film, she's paired off with Louis and becomes super-nerdy.
* {{Science Hero}}es: Three scientists and one academic student (Zeddemore, who gets a Doctorate later) face an ancient god with nothing but high technology equipment based on intensive scientific research of their supernatural opponents' nature, and ''totally kick their asses''.
* ScienceIsUseless: Inverted; the Ghostbusters' scientific methods always prove to be the only effective way of dealing with the supernatural, and the only use for other schools of thought is to provide info on what they're dealing with.
* SealedEvilInACan: The Ghostbusters' containment grid in the first film and Vigo's portrait in the second are used to trap ghosts.
* ShownTheirWork: The films are very, ''very'' thoroughly researched as side-effect of Aykroyd's own interest in the paranormal. For instance, Peter's treatment of the Zuul-possessed Dana is based on advice from exorcists and psychiatrists for dealing with cases of [[DemonicPossession possession]] and [[SplitPersonality DID]], respectively (i.e. you are ''never'' supposed to let the other personality remain in control; this is why he keeps insisting on talking to "Dana", and tries to ignore Zuul). In addition, ''all'' of the books Egon and Ray mention actually exist.
* SignsOfTheEndTimes:
** Part I:
--->'''Winston Zeddmore:''' Do you remember something in Literature/TheBible about the last days, when the dead would rise from the grave?\\
'''Ray Stantz:''' I remember Revelations 7:12. "And I looked as he opened the 6th seal, and behold, there was a great earthquake. And the sun became as black as sack cloth, and the moon became as blood."[[note]]This line is actually Revelation 6:12, Ray got the attribution wrong, though the quote itself is correct.[[/note]]\\
'''Winston Zeddmore:''' And the seas boiled and the skies fell.\\
'''Ray Stantz:''' Judgment Day.\\
'''Winston Zeddmore:''' Judgment Day.\\
'''Ray Stantz:''' Every religion has its myth about the end of the world.\\
'''Winston Zeddmore:''' Myth? Ray, has it ever occurred to you that maybe the reason we've been so busy lately is 'cause the dead ''have'' been rising from the grave?\\
'''Ray Stantz:''' [{{Beat}}] ...[[ChangeTheUncomfortableSubject How 'bout a little music?]]\\
'''Winston Zeddemore:''' [nods] Yeah.
** Part II:
--->'''Peter Venkman:''' Or you could accept the fact that this city is headed for a disaster of biblical proportions.\\
'''Mayor:''' What do you mean, biblical?\\
'''Ray Stantz:''' What he means is Old Testament biblical, Mr. Mayor. Real wrath-of-God-type stuff. Fire and brimstone coming from the sky! Rivers and seas boiling!\\
'''Egon Spengler:''' Forty years of darkness! Earthquakes! Volcanoes!\\
'''Winston Zeddmore:''' The dead rising from the grave!\\
'''Peter Venkman:''' Human sacrifice, [[ArsonMurderAndJaywalking dogs and cats living together]], mass hysteria!
** PlayedForLaughs after the firehouse blows up:
--->'''Vinz Clortho:''' This is it! This is the sign!\\
'''Janine:''' Yeah, it's a sign alright: "Going out of business".
* SlidingScaleOfComedyAndHorror: Straddles the line; the funniest moments and the scariest are often one and the same.
* SmarterThanYouLook: Although Venkman comes off as a cynical slacker who doesn't seem to get the gist of things as times, it's obvious that he has just as much knowledge of the supernatural as Ray and Egon.
* SpiritualSuccessor: Dan Aykroyd's failed attempts to get ''Ghostbusters 3'' done led to ''Film/Evolution2001''.
* SufficientlyAnalyzedMagic: The team did enough research to the paranormal, that they were able to develop the technology to properly detect and combat it.
* SupernaturalSealing: Showcases a rare technological version of this, with the Ghostbusters able to seal away malevolent spirits and even gods with MadScience.
* TechnoBabble: Brought to the point of art form: PKE valence. Focused, non-terminal repeating phantasm. Total protonic reversal.
* ThatCameOutWrong:
** While Peter is checking her apartment, he goes to the bedroom. Dana, without considering the implications, says "Nothing ever happened in there." Peter quips, "What a crime." Dana realizes her mistake, but instead chooses to focus on Peter's atypical attitude for a scientist.
** After the interview with Dana Barrett:
--->'''Peter Venkman:''' I'll take Miss Barrett back to her apartment and check her out.\\
[Dana Barrett looks up confused]\\
'''Peter Venkman:''' I'll go check out Miss Barrett's apartment. OK?
* ThemeTune: When there's something strange in the neighborhood … WhoYouGonnaCall? Ghostbusters!
* ThisIsGonnaSuck: In both films:
** I-- When Walter Peck is about to shut off the containment system, the 'busters deliberately place themselves near the stairs so they can easily flee when all hell breaks loose. Also Venkman's later line "I love this plan! I'm excited to be a part of it!"
** II-- In the courtroom, when the mood slime is about to explode, they slowly take cover under their table.
* TokenMinority: Winston. He shows up midway through the first film and joins the Ghostbusters, being the only main black character in either film. In the second he's out of the action until business picks back up, you guessed it, halfway through, being only a part-time birthday performer with Ray thanks to the lack of ghost activity.
* UnusuallyUninterestingSight:
** One of the buildings of New York becomes the portal to a hell dimension and nobody seems to notice or care.
** Louis Tully is pinned against the window of a fancy restaurant, then apparently ''devoured'' by a dog-like hellbeast the size of a horse. The patrons give this gruesome event a cursory glance, then carry on like nothing happened.
** Though, given how New York is depicted in these films, this is perfectly "in-character".
* VanityLicensePlate: The Ectomobile has ECTO 1 on its tags.
* WeaponsThatSuck:
** Technically speaking, the real weapon the Busters use against the ghosts are their traps, which suck the ghosts in and hold them until deposited in the protection grid. All the proton packs are intended for is to snare ghosts in the proton stream and position them above the trap. That's also why Busters didn't need the proton packs to capture the jogging ghost; all they had to do is place the trap in his path and open it when he stepped over it.
** The one exception to this are the final villains at the end of both movies. This may be explained by the fact that unlike the vast majority of ghosts Vigo and Gozer are at least semi-corporeal and, as we saw with the maid cart while they where initially catching slimer, a tightly focused stream from a proton pack can be highly destructive. Other non-corporeal ghosts can be restrained by it or in the case of relatively weak ghosts scattered into ambient PKE (psycho kinetic energy) but it would be possible to destroy a corporeal entity assuming it isn't a god or superpowered with PKE.
* WeirdnessCensor: Despite the rampant evidence to the contrary (as in, making this announcement during a mayoral meeting where everyone else in the room, including the mayor himself, is well aware of the supernatural crisis), Peck insists the Ghostbusters are frauds deluding people with chemicals and "a cheap, electronic light show." Indeed, Peck has zero evidence to back up his claims, having arbitrarily decided that they ''must'' be frauds. Had the case gone to court normally, the Ghostbusters would have won the case hands-down. In the second movie, several characters continue this attitude, which makes one wonder what they thought of the very public attack involving the very gigantic and very real Stay Puft Marshmallow Man and the very gooey remains he left behind.
%%* WhatTheHellHero: "What did you ''do'', Ray?"
%%* WhoYouGonnaCall: If there's somethin' strange... in the neighborhood... who you gonna call? [[TropeNamers Trope NAMER!!]] If there's somethin' weird, and it don't look good, who you gonna call? [[TropeNamers Trope NAMER]]!!
* TheWorfBarrage: The proton packs never work against the BigBad, or at best are a mild annoyance, which force the team to resort to different strategies to beat them.
** Gozer dodges the first shot and just vanishes the second time. Upon transforming into the Stay Puft Marshmallow Man, getting shot did little more than knock him down and [[ManOnFire set him on fire]], arguably making him even more dangerous.
** Vigo is briefly annoyed by the packs, brushing away the beams and paralyzing the team in the process. He has to be weakened by a CareBearStare[=/=]CombinedEnergyAttack in the form of happy, singing New Yorkers, which was the only way they were able to enter the building anyway. The final barrage of mood slime and proton packs also seems to hinge largely on the former, though the packs do provide the final push that wins the day.
** The games introduce three major modifications (complete with a secondary fire mode) to the classic backpack and most of the ghosts have a weakness to one of them: basic particle stream, dark matter generator, slime blower and meson collider. The idea is if one ghost is shrugging off any one of your attacks you can switch them up.
