The predecessor to Creator/{{Nickelodeon}} [[AllCGICartoon CGI series]] ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'', this 2001 movie was originally going to be simply a pilot episode for the series. Instead, the Creator/{{Nickelodeon}} executives were so impressed they gave it funding for cinematic release.

Ten-year-old boy genius Jimmy Neutron has an IQ of 210. He invents rockets in his spare time, for launching satellites to communicate with alien races. (Of course.) Jimmy also has a robotic dog called Goddard that can do [[DoAnythingRobot pretty much anything]], a disproportionately large head and [[AnimeHair a strange hairdo]] - a fact constantly brought to the surface by his rival, Cindy Vortex. He's just living his ordinary life (get up, get his robot to do his hair for him, travel to school via gum that turns into a transportation bubble, show off his shrink ray in Show And Tell, etc.) when the communication satellite he launched at the beginning of the movie is intercepted by some egg-shaped aliens named 'The Yolkians'. (The King is voiced by Creator/PatrickStewart, and his brother/comic sidekick Ooblar is voiced by Martin Short.)

[[Characters/TheAdventuresOfJimmyNeutron Character Sheet]] is here if wanted, but be warned - there are multiple spoilers for the series itself in there.
----
!!This movie provides examples of:
* AcademicAlphaBitch: Cindy.
* ActuallyPrettyFunny: When Judy accidentally drinks a beverage that causes her to belch endlessly, she at first is angry at Jimmy, but soon after finds herself laughing at the situation.
* AdultsAreUseless: Taken to its literal extreme, ThereAreNoAdults, in the movie, when the entire grown-up population of Retroville is kidnapped by aliens.
* AllGirlsWantBadBoys: A lot of girls, especially Cindy, have a crush on Nick for this reason.
* AliensAreBastards: You could say that they're bad eggs.
* AliensSpeakingEnglish: The Yolkians, who speak SurprisinglyGoodEnglish.
* AllCGICartoon: Notable for being the first film and series animated entirely with over-the-counter programs.
* AluminumChristmasTrees: Carl [[TheDitz eating toothpaste after launching into space, mistaking it for "space food"]]. Believe it or not, astronauts actually ''do'' eat toothpaste, but not because they like the taste. When brushing their teeth, they can't risk contaminating their airtight space capsules by spitting, so they instead use a special brand of non-toxic toothpaste that's designed to be swallowed after use.
* AnAesop:
** Your parents love you and they always want what's best for you. Listen to them.
** Don't talk to strangers.
** {{Be careful what you wish for}}.
* AnimeHair: Jimmy's. This is lampshaded pretty regularly.
* {{Area 51}}: Appeared in the movie.
* APlanetNamedZok: Yolkus, home of the Yolkians.
* ArsonMurderAndJaywalking: "You steal my parents, you threaten my dog, you attack my friends, and you make fun of my size!"
* AttackAttackRetreatRetreat: Nick Dean when he sees the BigBad for the first time.
* AttackOfThe50FootWhatever: Poultra, the Yolkian god, is a 50-foot ''chicken''.
* {{Adorkable}}: Jimmy.
* BatmanCanBreatheInSpace: Played straight in the movie, Lampshaded in the series.
* BeCarefulWhatYouWishFor: The wish to get rid of all parents comes back to bite the kids after one day.
* BelligerentSexualTension: Jimmy and Cindy.
* BerserkButton: Jimmy doesn't like it when people make fun of his size. Especially Goobot.
** Don't harm Jimmy in front of Goddard.
* BlackBestFriend: Libby to Cindy.
* BrickJoke: Burping Soda. In the beginning of the film, it's part of Jimmy's invention displays. It comes back in the last scene.
** Blink and you'll miss the payoff of this one. At the beginning, Jimmy uses the toaster as a satellite to send a transmission to the Yolkians. When he later compares the note the Yolkians left to past notes his parents wrote, the first note says his mother went shopping for a new toaster.
* BumblingDad: Hugh.
* BumblingSidekick: Ooblar.
* CaptainObvious: When Hugh investigates the green light in the kitchen, expecting Jimmy to be the cause of it, and discovers an alien in there, what does he say? "You're not Jimmy." [[SarcasmMode Really?]]
* CatchPhrase: Jimmy - "Gotta blast!"
* ChekhovsBoomerang: The Shrink Ray. First shown by Jimmy during show and tell, then Jimmy uses it to shrink himself so he can sneak out and go to Retroland, [[spoiler:then he uses it again at the end to make himself the size of a planet and defeat Goobot.]]
* ChekhovsGag: Carl's gaffe during show and tell comes back as significant in the Yolkus arena when Carl blinds one of the aliens with his inhaler and the alien crashes into a wall.
* ChekhovsGun:
** Jimmy's blast gun, used in one of the early scenes by Jimmy to fire at an invention that makes his bed for him, is later used by one of the kids in the climax to take out one of the aliens.
** Purple Flurp. Cindy drinks it during a tai chi session, Jimmy hopes there's some in the fridge the following morning, then Cindy drinks some in the climax before taking out one of the aliens, in a similar manner to Jimmy's blast gun above.
** Many of the rides at Retroland are used as spaceships by the kids.
** As described above, Carl's inhaler.
** The toaster.
** While Goddard hides under Jimmy's blankets he records Jimmy's parents trying to comfort him when they won't let him go to Retroland, as they close the door they said they'll see him tomorrow. The aliens left a message on each house saying the parents are going to Florida for orange juice. When Goddard played the message to Jimmy, he realizes something's off.
* ChekhovsSkill: Goddard playing dead. ([[spoiler:When told to play dead, he detonates in a small explosion before reassembling himself]]).
* ChildProdigy: Jimmy, being about yen years old and probably the smartest kid in Retroville. He even calls himself a genius.
* ComicallyMissingThePoint: Jimmy, when trying to come up with a plan that will enable him, Carl and Sheen to go to Retroland that evening, he cites the influence of positive reinforcement as an idea, citing the giving of bananas to monkeys as an example, and the same principle should work on their parents. Carl remarks that his dad is allergic to bananas.
* ComicTrio: Jimmy, Sheen, and Carl.
* ContrivedCoincidence: Jimmy, Sheen and Carl wish on a shooting star (actually a departing alien spaceship) for no more parents on the very night the parents are abducted. The next morning, they realise their wish came true.
* DeathGlare: Jimmy to Goobot after Goobot mocks Jimmy's size. Happens twice. [[spoiler:The second time it happens, Jimmy's the size of a planet and Goobot's ship nearly crashes into him.]]
* DepartmentOfRedundancyDepartment: "As the King's royal assistant, I am the official checker of the official things to be checked!"
* DidntThinkThisThrough: Jimmy's transmission to the aliens was a bad idea because he had no idea of the nature of the aliens who would pick it up.
** Crossing over with BeCarefulWhatYouWishFor (though they weren't prepared for what happened anyway), as the kids have a lot of fun without their parents, but come the next day, it's pretty clear their wish for freedom has backfired on them.
* DoAnythingRobot: Goddard.
* DuelingMovies: With ''WesternAnimation/RecessSchoolsOut'' (Though they didn't compete with each other- ''School's Out'' had already been released on video)
* EarlyInstallmentWeirdness:
** In the animation department: Cindy's hair; pigtails in the movie, ponytail in the series that came after. All the kids had different character designs. Jimmy wore shorts and loafers instead of sneakers and jeans, Carl wore suspenders, and Sheen had collars on the end of his sleeves. Goddard also talks while giving Jimmy options, though his abilities do depend on the writer.
** Several characters behave significantly different than they do in the TV series:
*** Cindy (and, by extension, Libby) is way nicer and more supportive to Jimmy than she ever is in the show.
*** Hugh has quite a few mature moments in which he acts more like a caring father and husband than the bumbling comic relief known from the TV series.
*** Nick is pretty much just a JerkAss whose solution to all problems involves punching the crap out of whoever's in the way, as opposed to him from the show, where he is just a harmless self-obsessed "cool kid" that's difficult to be taken seriously and a BigBrotherMentor to Jimmy.
*** Sheen is smarter than he is in the TV series and his own (which is saying a lot).
* EstablishingCharacterMoment: King Goobot is introduced devouring his pet alien while Ooblar is introduced being overly excited about what Jimmy Neutron sent them and having no idea what toast is.
* EurekaMoment: Jimmy has two, where the camera zooms through his ear into his brain as he tries to think of an idea, and goes "Brain blast!" when he gets one of these.
* EverybodyLaughsEnding
* ExplainExplainOhCrap: Jimmy realises mid-sentence that Judy won't let him go to Retroland.
* FatAndSkinny: Carl is the Fat to Jimmy's Skinny.
* {{Foreshadowing}}: As the kids in their rockets see the sun before the meteor shower, Jimmy and Cindy briefly share a smile before each of them turn away.
* FunnyBackgroundEvent: While watching Jimmy's message, Ooblar absentmindedly munches on the piece of toast he had enthusiastically greeted earlier in the scene, getting a rather disturbed look from King Goobot in the process.
* GettingCrapPastTheRadar:
** Jimmy's whole puberty talk with Carl on how one day they'll have to start liking girls against their will.
** Of course we know what the [[{{Hell}} theme]] for the ride "Bat Out of '''Heck"''' is going to be.
** "I'm ''peeing'' in the shower!"
** Might be unintentional, but while Jimmy was inspecting the conversion of theme park rides into spaceships, there were kids prepping a dragon ride by preparing to move a rocket into an [[{{AssShove}} interesting place]].
** This little exchange between Jimmy and vaguely native-looking Nick:
---> '''Jimmy''' (pointing at the stars): Hey, there's a red giant! And that's a white dwarf!
---> '''Nick''': You can relate, huh, Neutron?
* GirlsHaveCooties: Jimmy, Sheen, and Carl all exhibit this sentiment from time to time. Especially Jimmy, who engineers a man-eating plant to target girls with pigtails (Well, mainly Cindy, anyway).
* GoneHorriblyRight: All Jimmy wanted to do at the start of the film was to make contact with an advanced alien civilisation. [[spoiler: He succeeded, all right. Turned out the aliens picked up the satellite and abducted the parents in Retroville to use them as sacrifices for Poultra. Oops.]]
* GoodBadBugs: [[InUniverse Goddard's "Play Dead" mode]], which is a SelfDestructMechanism. Although fixing that was on Jimmy's to-do list, he decided to "make that bug a feature" after it helped [[spoiler:bust the kids out of the dungeon]].
* JerkAss: Nick.
* JerkassHasAPoint: [[LampshadeHanging Lampshaded]] by Jimmy when Nick points out that there's only one opening night at Retroland and that every kid who cared would be there.
--> '''Jimmy:''' "Nick has a point. There is only one opening night."
* JerkWithAHeartOfGold: Cindy.
* KickTheDog:
** In his opening scene, King Goobot devours an adorable alien. In his second scene, he gets a BadBoss moment. [[BerserkButton Then there are the times he mocks Jimmy's size]].
** Ooblar later tries to do the same to Goddard. He fails miserably.
* TheLancer: Carl is this to Jimmy, being more dopey [[CowardlySidekick and cowardly]] than him.
* LargeHam: Both King Goobot and Ooblar have their moments. "[[CrowningMomentOfFunny HELLO, TOAST!]]"
* MeaningfulEcho: "Now, you gotta admit, ''that'' is pretty neat."
* MeaningfulName: James 'Jimmy' Isaac Neutron is not surprisingly, interested in science.
** Jimmy's name comes from ''two sceintists'' : Isaac Newton, and perhaps more importantly James Chadwick, who discovered neutron atoms.
** Sheen Estevez; a ShoutOut to Martin/Charlie Sheen and Emilio Estevez.
** Not to mention Retroville. Even the science fiction aspects of the movie have a RaygunGothic feel.
* MinionWithAnFInEvil: Ooblar.
* MissingMom: Sheen. WordOfGod says his mother died when he was young - they don't say her cause of death, however. Fits also with EarlyInstallmentWeirdness: Sheen's mom is clearly present in the end scene with Sheen's dad. His dad also displays a very different attitude from his few appearances later in the series (he's much... more fatherly than he later was shown to be.) She just suffered ChuckCunninghamSyndrome that was retroactively remade into her having died when Sheen was little.
* MissingTrailerScene: Pretty much everything in [[http://www.youtube.com/watch?v=LmLoVgbJhk8 the teaser]]. Justified, as a lot of it is very early test footage. Most of the scenes got recycled for smaller shorts that premiered during commercial breaks on Nickelodeon around the time the film came out.
* NerdsAreInnocent:
** Jimmy is a child prodigy who loves and excels at science... and still believes in cooties.
** Carl fits this too. He's a timid, sensitive SicklyNeuroticGeek.
* NewscasterCameo: A variant: ''Series/EntertainmentTonight'' hosts Bob Goen and Mary Hart voice "Yolkian Tonight" anchors, commenting on the sacrifices to Poultra.
* NiceJobBreakingItHero: [[spoiler:Jimmy sending the aliens information about Earth against his parents' orders is a very bad idea.]]
* OhCrap: A fair bit of it.
** Jimmy gets one after his rocket sets the curtains on fire.
** He also gets one later [[spoiler:after his satellite is picked up and the aliens reveal ''he'' is the reason the parents were located and are going to be sacrificed. [[NiceJobBreakingItHero Oops]].]]
** Jimmy, Carl and Sheen get one on the Bat Outta Heck! ride at Retroland before plummeting into darkness.
** Jimmy and Carl when confronted about the missing parents (with flaming torches, for Pete's sake!). [[ScreamsLikeALittleGirl Carl's reaction]] is very funny.
** Ooblar has one after [[spoiler:Jimmy, through Goddard's speaker, tricks him into thinking Goddard is going to explode.]]
** Nick gets quite a funny one in the arena after Poultra's eyes hatch out of the egg.
** Goobot gets one after [[spoiler:Jimmy uses The Shrink Ray on himself to make himself the size of a planet.]]
* ParentsInDistress
* PetTheDog:
** Rather than being condescending, Jimmy is very nice to the rather dopey Carl and nerdy Sheen, not being a wet blanket when Carl shows him a picture of a frog or talks about wishing on a star.
** Also, Cindy giving Jimmy advice after all the kids are angry at him [[NiceJobBreakingItHero because he caused their parents to get kidnapped.]]
** Nick at the end gives Jimmy a genuine congratulations for rescuing the parents and he's more than happy to be reunited with his mother.
* PunnyName: Ms. Fowl has a few bird-like attributes.
* RealityEnsues: At first, all the kids of Retroville are thrilled that there are no parents around to enforce the rules and party like there was no tomorrow, but by the following day, everyone soon starts to realize just how much they need their parents to support their lives and care for them, when injuries, stomachaches and other problems start to arise, with kids starting to run around crying for their parents.
* RetroUniverse: Retroville.
* RobotBuddy: Goddard.
* SassyBlackWoman: Libby.
* SchmuckBait
* ScienceHero: Jimmy, who solves the problems his inventions create.
* ScienceInGenreOnly
* SciFiWritersHaveNoSenseOfScale: More than one instance.
** The toaster Jimmy sends into space to contact alien life forms is just barely given enough oomph not to fall back to Earth. This should put it in a low Earth orbit or, at best, send it out on a long slow trajectory into interplanetary (but not interstellar) space. Maybe in a few months it might get as far away as Mars. Yet it's discovered by an alien deep space fleet that was so far away from Earth they had no way to detect Earth on their own.
** Jimmy cobbles together a fleet of spacecraft using "fusion engines" and "pulse rockets" with which to fly to the alien homeworld. The alien homeworld is ''three million light-years away.'' Yet they're able to make the trip in a couple of days.
** Jimmy uses his machine to grow [[spoiler:"Planet Sized" in the end of the movie, but in fact he becomes only a few times larger than the alien spaceship.]]
* ScreamsLikeALittleGirl:
** Nick after seeing Poultra.
** Carl when he learns there is an angry mob coming at him and Jimmy.
* SelfDestructMechanism: Goddard has one, though he can reassemble himself. Jimmy also ''pretends'' that Goddard is about to self-destruct in a "50 megaton blast" in order to scare away Goddard's captor.
* SequelHook: Odd version used in one of the audio tracks. ''Leave it Up to Me'' includes half a verse about it, complete with the rather blatant lyrics:
--> '''Aaron Carter:''' "Big people listen up, relax now, we're equal; and if the money's right then we might make a sequel."
* ShoutOut:
** Nick describes ''Film/TheBlairWitchProject'' to the rest of the kids at the camp on the asteroid.
** The first thing Jimmy does in his alien transmission is the [[Franchise/StarTrek Vulcan salute]].
** [[http://www.youtube.com/watch?v=N3F5SHvkERQ The second trailer's opening]] is a huge one to ''Film/TopGun'', down to using "Danger Zone".
** During 2007, Nickelodeon aired a special version of the movie, with Jimmy, Sheen, and Carl riffing on the movie as an extended reference to [[Series/MysteryScienceTheater3000 MST3K]], complete with "Shadowrama" versions of the cast.
* ShutUpHannibal: "Well, I may be small, but I've got a big brain!" [[spoiler:He then makes himself the size of a planet with the Shrink Ray and blows Goobot's ship into an asteroid.]]
* SmartAnimalAverageHuman: Jimmy Neutron and his robotic dog, Goddard. PlayedWith because although Jimmy himself built Goddard, Jimmy is only a kid and can make foolish decisions sometimes. Goddard is wise and is usually the voice of reason to Jimmy by giving him suggestions on what he should do and feels ashamed when Jimmy makes bad decisions.
* TheSmartGuy: Jimmy is very much this, having created everything in his own underground lab under his house, probably having built the lab himself in the first place, and comes up with many plans in the film himself. However, despite his intelligence, he is still a ten-year-old kid and [[DidntThinkThisThrough sometimes makes]] [[NiceJobBreakingItHero bad decisions]].
* SpaceDoesNotWorkThatWay
* SuddenlyShouting: Nick does this twice in the cell when talking to Sheen regarding Ultra Lord.
--> '''Nick''': "Maybe sit on a shelf, because he's a DOLL!"
--> '''Nick''': "That's pretty much the STUPIDEST THING I EVER HEARD!"
* TakeOffEveryZig: When the kids take off in their space ships crafted from amusement park rides.
* {{Tsundere}}: Cindy. In the original movie she explains that she only became one to Jimmy, because she was jealous of his better grades and hated his tendency to show off his intelligence on every given occasion.
* WhamLine: "Good night, Jimmy. Sweet dreams. We'll see you in the morning."
* WhereTheHellIsSpringfield: Averted, Retroville is located in Texas.
