A [[SlidingScaleOfComedyAndHorror thriller/comedy]] (or "thrillomedy") film released in 1990, ''Arachnophobia'' featured Jeff Daniels and John Goodman and was produced by Creator/StevenSpielberg. This was the first film directed by Frank Marshall. It was also the first film released under {{Disney}}'s [[Creator/HollywoodPictures Hollywood Pictures label]].

The film concerns about an unknown species of spider living in an isolated sinkhole within the South-American Jungle. These spiders operate with a hive mentality and carry a super-potent venom that kills in a matter of seconds. When one of the spiders is accidentally transported to a sleepy California town from Venezuela in the coffin of its first victim and later mates with a common House Spider, the hybrid descendants terrorize the town for weeks while the newly-arrived city-mouse town doctor (Daniels) struggles to make sense of the mysterious deaths. Aiding him is an EccentricExterminator played by Goodman in one of his most popular roles. The film was a financial and critical success thanks to its mix of horror and humor.

There was also an MS-DOS game released that was vaguely related to the movie, in which the player took control of Goodman's character who was sent to eliminate the spiders.

!!This movie has examples of:

* AerosolFlamethrower: Effective against deadly spiders. Appears in both the movie and as the ultimate weapon in the game.
* TheAmazon: The killer spiders come from an unexplored jungle in Venezuela.
* AnswersToTheNameOfGod
-->'''[[BadassUnintentional Ross]]:''' (After destroying the nest with his ImprobableAimingSkills) Thank God.
-->'''Delbert:''' Don't mention it.
* AssholeVictim: [[spoiler:Dr. Metcalf is a contrarian, pompous jerkass who screws over Jennings, so his death by one of the spiders is a bit karmic.]]
* AutopsySnackTime: A mortuary worker munches a sandwich while the crate containing the photographer's body is being opened, then sets it down on a worktable used for preparing bodies. Later on he has a bag of chips with him when Dr. Jennings, the morgue and the scientist's assistant examine three bodies in search for spider bites.
* AwesomeMcCoolName: Delbert [=McClintock=].
* BrotherChuck: Chris disappears after trying to pull Ross out of the house near the end.
* BrickJoke: [[spoiler: "Not the Chateau!"]]
* ChekhovsGun: In the beginning, the main character Dr. Jennings is introduced to a nail gun by carpenters building his wine cellar, and later happens upon said nail gun in the final act of the movie.
* TheCityVsTheCountry: The doctor and his family move into a small town. The townspeople immediately resent him for being from the city.
* CobwebJungle: A lot of areas become this after the spiders are released, but Dr. Jenning's barn is by far the best spot.
* CompletelyDifferentTitle: In Sweden the movie is known as "''Imse vimse spindel''" translating as "Itsy Bitsy Spider".
* ConnectTheDeaths: Used when Dr. Jennings is figuring out where the spiders' nest is. [[spoiler: Naturally, given his crippling fear of spiders, it's his own house.]]
* CorruptHick: Sheriff Parsons.
* EccentricExterminator: John Goodman's character Delbert [=McClintock=] has various quirks, but seems like a nice guy. He also has a bit of an inflated opinion of himself, but he does come in handy [[spoiler:when he kills most of the drone spiders at the end.]]
* TheEndOfTheWorldAsWeKnowIt: Implied by Dr. Atherton. The spiders are a hive species, giving birth to androgynous soldier drones, but after the hive gets big enough, the queen would be able to birth a young queen to make her own hive somewhere. Atherton says this would happen once the town has been devoured, and more than one young queen would be produced. Take this to its logical conclusion...
* EpiphanyTherapy: "Come to the barn and look at this gigantic web taking up most of it. That'll cure your arachnophobia."
* EvilDetectingDog: Both a cat and a dog can sense that the General is, if not technically evil, than certainly not to be messed with. A crow does not realize this in time.
* EvilOverlooker: This film is a fairly subtle example. Take a good look at the moon on the poster/cover.
* FailedASpotCheck: Delbert, primarily, but most of the sheer terror of this film comes from how easily the spiders are overlooked.
* FanDisservice: There's a scene of a girl showering when one of the lethal, venomous spiders crawls out of the shower head. She remains oblivious as he gets washed off her body until she notices the spider dissappearing down the drain.
* FullMoonSilhouette: Not shown in the film, but posters for the movie depict a spider hanging on a silk thread in front of a full moon.
* GiantSpider: Mostly averted. None of the spiders in this film are larger than your hand, but they ''are'' deadly venomous. Downplayed with the original spider, the General, which is the size of a baseball mitt--giant enough.
** I'm sorry, did you say '''GIANT ENOUGH?!'''
* InfernalRetaliation: The General proves to be a hardcore little bugger even after being set alight.
* ItsQuietTooQuiet: It's repeatedly mentioned that the main character doesn't hear crickets, despite living in the country. That's because [[spoiler: the main webs are in his barn.]]
* {{Jerkass}}: Dr. Metcalf arranges with Dr. Jennings for him to take over his small town clinic when he retires. Then Metcalf decides on the fly to go back on his promise when Jennings has already bought a home and settled his family in town. He views him with unjustified contempt as a big-city wig who looks down on the townspeople, badmouths him to the town, and berates his concern about the increasing sudden deaths largely out of spite.
* MisplacedWildlife: The spiders are ''Delena cancerides'' from New Zealand, [[http://www.imdb.com/title/tt0099052/trivia a species known for being slow and harmless]]. This is somewhat evident to the arachnology fan watching the film, as they are so slow and inert that they sometimes have to be urged to move by sticks that are visible in-shot. The "big bad" spider toward the end is a bird-eating tarantula, more dangerous owing to being large and aggressive (if not particularly venomous). The film is set in the USA, though the spiders supposedly come from South America.
* NailEm: Ross kills a spider with a nail gun, albeit one meant to patch holes in starships.
* NeverTrustATrailer: The trailer used lighthearted music and put major focus on John Goodman's role as a quirky exterminator, making it look to be a lighthearted comedy. Turns out that while there are comedic scenes, the film is basically nightmare fuel (or considering the film is about spiders, would that be nightmare venom?)
* OrificeEvacuation: A spider crawls out of one of the victims' noses when the body is discovered.
* PrimalFear
* TheProfessor: There's an entomologist named Prof. Atherton, who is usually referred to by John Goodman's character as 'The Professor'.
* ShoutOut: Delbert's attire is largely inspired by ''Franchise/{{Ghostbusters}}''. The ''MAD Magazine'' parody, ''A Knack For Phobias'', makes the connection explicit.
* SpidersAreScary: The film is about a group of hybridized spiders that invaded a California town and begin killing the inhabitants that live there.
* SpiderSwarm: Played UpToEleven. The Venezuelan spider species presented in the film consists mostly of drones that lack sex organs, and they have a hive with a queen similarily to bees or ants. It is implied that if let to breed freely, the spiders would eventually give birth to a new queen capable of birthing fertile offspring, eventually leading to [[TheEndOfTheWorldAsWeKnowIt the whole world being overrun]] by the extremely aggressive and venomous strain of spiders.
* SuperOCD: Dr. Metcalf walks his treadmill (rather than around the neighborhood with his wife) because he must know ''exactly'' how far he's gone and ''exactly'' how long it took.
* TooDumbToLive: [[spoiler:Dr Atherton. He's the foremost spider expert in the country, and he's been extensively informed how dangerous the new breed of spiders are. He sees no problem however in investigating the huge spider's nest in the barn all by himself, with no protection whatsoever. And then deliberately twanging the spider's web, apparently to get it to show its face. Predictably, he dies within minutes]].
* WhatHappenedToTheMouse: Ross' friend Chris survives the spider infestation and manages to escape from the house with the family; he is last seen trying to pull Ross out of the house on a ladder but is knocked over. He is never seen again after that.
* WhyDidItHaveToBeSnakes: Doctor Jennings is deathly afraid of spiders because of an encounter with one in his infancy.
* TheWorldsExpertOnGettingKilled: [[spoiler:The entomologist who knows all about the killer spiders goes down like a RedShirt. Perhaps a little more acceptable than most examples because he's a scientist, not a hunter, but he still wasn't very careful despite knowing how dangerous the spiders were.]]
