->''"[[TagLine There are 3.7 trillion fish in the ocean. They're looking for one]]."''

A 2003 computer-animated film from Creator/{{Pixar}}, and the first one from the company to win the Oscar for Best Animated Feature.

The movie takes place in and around the Great Barrier Reef near UsefulNotes/{{Australia}}, and centers on a neurotic clownfish named Marlin. After losing his mate and all but one of their 400+ eggs in a barracuda attack, Marlin becomes overprotective of his remaining son, Nemo. On his first day of school, Nemo gets fed up with Marlin's fear of the ocean, and ends up disobeying his father's orders by going near a boat. Soon after, Nemo gets "rescued" by a scuba diver, and Marlin, going against all his fears, goes off to find him. Marlin joins up with a forgetful blue tang named Dory, and they brave all sorts of obstacles to, well, [[ExactlyWhatItSaysOnTheTin find Nemo]].

Meanwhile, the scuba diver turns out to be a UsefulNotes/{{Sydney}} dentist who puts Nemo in his office's aquarium, and plans to give the fish to his niece, Darla, for her upcoming birthday. The other fish in the tank, most of whom are somewhat insane, decide to help Nemo escape (especially because Darla is described as a "fish killer", who, whenever she gets a fish, shakes their plastic bag too hard).

This movie is notable for being Pixar's most commercially successful feature[[note]]let alone a G-rated one[[/note]] until ''WesternAnimation/ToyStory 3'', but it's still one of the highest-grossing animated movies ever made as well as the highest-selling DVD ''ever''. It also started Disney's [[OscarBait Oscar-winning streak]] and was honored with a Disney Digital 3D [[ThreeDMovie re-release]]. It didn't exactly hurt the tourism trade in Australia, either. A sequel, titled ''{{WesternAnimation/Finding Dory}}'', is set for June 2016. EllenDegeneres will be returning as Dory.

!!This film contains examples of:

* ThreeDMovie: In September 2012. March 2013 in Europe.
* AcCENTUponTheWrongSylLABle:
--> '''Dory''': Hey, look. "Ess-cop-ay". I wonder what that means? That's funny, it's spelled just like the word "escape."
* AcceptableTargets: [[InvokedTrope Invoked]] by the sharks.
-->'''Anchor:''' Except stinkin' dolphins!
-->'''Chum:''' Dolphins! Yeah, they think they're so cute! "Look at me, I'm a flippy little dolphin, let me flip for you, ain't I something?!"
** And...
-->'''Chum:''' Humans! [[HumansAreTheRealMonsters Think they own everything.]]
-->'''Anchor:''' [[TakeThat Probably]] [[EagleLand American.]]
** That last one also counts as SelfDeprecation on behalf of the filmmakers.
* AccidentalMisnaming: The absent-minded Dory keeps misremembering Nemo's name.
* AcquiredPoisonImmunity: Sort of. The baby jellyfish's sting doesn't bother Marlin because he lives in an anemone and is already used to stings.
* AdultFear: To a parent: your family is decimated before it even has a chance to begin. You lose the love of your life, and your innocent child is hurt. Years pass, and you try to protect your child as well as you know how -- and then a horrible, monstrous force steals your child away, and you lose all trace of them...
** And after journeying for days in search of said child, arriving to find them dead.
* AdvertisedExtra: For some reason, Bruce and Crush are always shown on just about every piece of promotional material as two of the film's central characters even though their screen time is limited to only a handful of scenes.
* AffablyEvil: Subverted. Bruce appears to be this towards the beginning of the movie, but it's revealed that he's actually a NiceGuy. [[spoiler:Unless he smells blood.]]
* AllThereInTheScript: Gurgle's never referred to by name. He's the purple and yellow one.
* AlluringAnglerfish: Provides the [[NightmareFuel unsettling]] page image for said trope.
* AlwaysABiggerFish: Averted [[spoiler: in the stinger sequence with the anglerfish.]]
* [[AndCallHimGeorge And I Shall Call Him Squishy]]: Said outright by Dory. And Darla, possibly.
* AnimalsLackAttributes: Poor Bruce was originally animated with prominent claspers, as would be appropriate for a shark his size. Obviously they didn't make it to the final version.
* AnimalTalk: Most of the animals in the film talk to each other, even those that belong to different classes. The exceptions are those without complex nervous systems (sea anemones, jellyfish), predatory fish, and the whale (although it does seem to understand Dory speaking whale).
* AntiVillain: Nearly every villain in this movie is either ObliviouslyEvil (like Darla and the jellyfish), predatory (anglerfish and barracuda), or just lacking in self-control (like Bruce and the seagulls) and the closest thing to bad guys would be [[spoiler:the fishermen towards the end, but even they probably see what they're doing as okay like most fishermen in real life do]]. This movie overall has arguably the mildest villains in Pixar movie history. To be more precise:
** Type 3: Darla, the dentist.
** Type 4: Jellyfish and the [[spoiler: fishermen]], under the "mere predator" definition.
* ArgumentOfContradictions: There is a brief one over what type of tool the dentist was using.
* ArtisticLicenseBiology:
** Barracuda don't have much of taste for eggs. They prefer live prey.
** The interior of the whale's throat is too large. While blue whales have a gigantic '''''mouth''''', their throat is tiny and unable to swallow anything larger than a beach ball.
** They also have respiratory and digestive traits completely separated, you know, so that they don't unintentionally [[spoiler:sneeze fish out of their blowhole.]] [[HollywoodDarkness And where is the light inside its mouth coming from?]]
** Chuckles, the gift fish who was killed by Darla, was a goldfish. Which live in freshwater. The other Tank Gang fish are saltwater fish. You can see where this is going.
** None of the sea turtles seem to worry about having to breathe. They also don't travel in flocks, but this was intentional, see RuleOfCool below.
** Sea turtles don't live anywhere near 150 years; that honor belongs to tortoises. Their expected lifespan is still quite impressive at 80 years.
** Clownfish do live in anemones but they also live in harems dominated by one male and one female, with a lot of non-productive males in the rest. When the dominant female dies, the dominant male undergoes a GenderBender and becomes the new dominant female. Clownfish will also reproduce with their relatives in times of emergency. This particular tidbit has raised eyebrows at the choice of clownfish for the film.
** Interestingly, a featurette on DVD addresses the whole Artistic License issue. An animator relates a story of one of their consultants talking about the biological inaccuracies in their final fish designs. The animator replied, sheepishly, "Well...in real life they don't ''talk'' either, so..."
* ArtisticLicenseEngineering: All drains ''do'' lead to the ocean (or at least a river or lake). It's just that raw sewage isn't dumped directly into the water; there are a number of mechanical and chemical processes in the way that, if depicted in the movie, [[FamilyUnfriendlyDeath would probably not be pleasant.]]
* AscendedToCarnivorism: The movie ends with a [[TheStinger Stinger]] of [[spoiler: the little green fish Blenny from the sharks' meeting gobbling up the [[AlluringAnglerfish Anglerfish.]]]]
* AsLongAsItSoundsForeign: A comedic example with Mt. Wannahockaloogie.
* AttentionDeficitOohShiny: "Hello, I'm Dory. What, you want to look for your child? Ummm... [[http://en.wikipedia.org/wiki/Anterograde_amnesia Hello, my name is Dory ...]]"
** [[InvokedTrope Deliberately invoked]] by Marlin when he gets Dory to follow him above the trench rather than through it.
* AxCrazy: Bruce, when he smells blood. Given what he is and what happens when they smell large amounts of blood, can be justified.
* BadassOnPaper: Marlin gets through most of his adventures by gumption, desperation, and sheer dumb luck, but as his exploits are recounted over and over he starts to sound more and more badass. By the time the stories get to Nemo, his father is a PapaWolf who has battled sharks and fought off jellyfish.
* BadassUnintentional:
** Dory. She just wants to hang out with Marlin.
** Thanks to [[PapaWolf his hijinks]], Marlin gets this reputation throughout the entire ocean area surrounding Sydney.
* BehindTheBlack: The diver just sort of appears behind Nemo with no one noticing him before then.
* BewareTheNiceOnes:
-->'''Crab:''' [[JerkAss Yeah, I saw him [Marlin], Bluey. But I'm not tellin' you where he went.]] [[TemptingFate And there's no way you're gonna make me!]]
-->([[DeathGlare Dory glares at him]], [[CoolAndUnusualPunishment cut to the crab being]] [[JackBauerInterrogationTechnique lifted out of the water near a bunch of seagulls.]])
-->'''Seagull:''' [[CatchPhrase Mine?]]
-->'''Crab:''' Ahh! Alright! I'll talk! I'll talk! He went to the fishing grounds!
* BilingualBonus: "Nemo" is Latin for "nobody".
* BlackEyesOfEvil: Bruce, when he smells blood.
* {{Blipvert}}: A high-speed montage of the beginning of their quest to when they finally reach Sydney plays when Dory remembers the address on the scuba gear.
* BodyMotifs: Three fish characters have an injured or otherwise unusual right fin -- Nemo (in the opening scene), Gil (before he's been introduced), and Dory (during her near-fatal encounter with the jellies).
* BowelBreakingBricks: Octopus ink.
* BracesOfOrthodonticOverkill: Darla dons a set of truly scary-looking headgear.
* BreakUpMakeUpScenario: when Marlin thinks Nemo is dead and leaves Dory. Also with his son before he is kidnapped.
* TheCameo / CastingGag: John Ratzenberger has his mandatory Pixar appearance, this time as the school of fish that gives Marlin and Dory directions.
* CannotTellAJoke: Marlin at the start of the movie.
* CarnivoreConfusion: "Fish are friends, not food!"
** [[PlayingWithATrope Played with]] in the case of the pelicans: they eat fish -- but not if they know the specific fish personally.
* CensorshipBySpelling:
-->'''Gurgle''': Whatever you do, don't mention D-A-R...\\
'''Nemo''': It's okay, I know who you're talking about.\\
''*Bloat {{dope slap}}s Gurgle*''
* CheerfulChild: Nemo.
* ChekhovsGun: "P. Sherman 42 Wallaby Way Sydney!"
* ChekhovsSkill:
** Gill saves Nemo from the first net by having them swim down. Nemo then goes on to use this technique to save a whole school of fish.
** The clownfish's ability to swim through jellyfish unharmed works out for Marlin... [[spoiler: but not for Dory.]]
** If he gets stung enough, [[spoiler:it even knocks Marlin out.]]
* ChronicPetKiller: Darla.
* {{Cloudcuckoolander}}: Dory. She is the '''QUEEN''' of Cloudcuckooland. Part of it's due to her short term memory loss but anyone who thinks they can speak whale and ask a shark for directions is working on strange logic indeed.
** Worth noting is that both things WORK.
** Deb/Flo and Bubbles also count.
* CloudcuckoolandersMinder: Poor Marlin.
* TheCloudcuckoolanderWasRight: Dory really can speak whale. Also, she was right about going through the trench instead of over it.
* ComeWithMeIfYouWantToLive: "Hop inside my mouth if you want to live."
* CoolTeacher: Mr. Ray.
* ContinuityCameo: In P. Sherman's waiting room, there is a [[WesternAnimation/ToyStory Buzz Lightyear]] on the floor next to the chest of toys.
** [[WesternAnimation/MonstersInc Mike]] appears in the closing credits.
* CrazyPrepared: Gill
* CreativeClosingCredits
* CreatorCameo: Director Andrew Stanton is the voice of the gnarly Crush and the lobster with the Boston accent.
* CubCuesProtectiveParent: When Marlin slaps away a baby jellyfish with his tail after it stings Dory, the swarm of adult jellyfish immediately start swimming toward them.
* CurseCutShort: "We are swimming in our own SHI-"
* DarkerAndEdgier: Somewhat, Pixar's first four films had some more emotional moments but on the whole they were very lighthearted and comedic. ''Finding Nemo'' was arguably Pixar's first foray into more dramatic territory, as in films that have comedic elements but on the whole aren't comedies.
* DeadpanSnarker: Marlin.
* {{Dedication}}: The film is dedicated to Glenn [=McQueen=], an animator who passed away from melanoma before the film's release.
* DemotedToExtra: Remember that pelican Gerald that [[spoiler:swallows Marlin and Dory]]? Initially in production he and Nigel were originally going to be ThoseTwoGuys, Nigel being the neat freak of the two, Gerald being scruffy and sloppy. In the finished film, Gerald's final screen time is less than a minute.
* [[TheElevatorFromIpanema The Dentist's Office From Ipanema]]: When Nemo first arrives in the tank.
* DepartmentOfRedundancyDepartment
-->'''Dory''': [[AndCallHimGeorge I shall call him Squishy]], and he shall be mine, and he shall be my Squishy.
* DerailedForDetails / CannotTellAJoke:
-->'''Marlin''': All right, I know one joke. Um, there's a mollusk, see? And he walks up to a sea, well he doesn't walk up, he swims up. Well, actually the mollusk isn't moving. He's in one place and then the sea cucumber, well they—I mixed up. There was a mollusk and a sea cucumber. None of them were walking, so forget that I --
* DespairEventHorizon: [[spoiler:Marlin, when he and Dory return to the sea after he believes Nemo to be dead, and Dory, after Marlin leaves her.]]
* DepthDeception: Dory and Marlin try to speak to a small fish while looking for directions to Sydney. Turns out, it's not small, so much as ''[[Series/FatherTed very far away]]''.
* {{Determinator}}: Many characters in the movie, but especially Marlin, Dory, and Gill.
-->'''Nemo:''' How many times have you tried to escape?
-->'''Gill:''' Eh, I've lost count. Fish aren't meant to be in a box, kid.
* DidYouDie:
-->'''Turtle''': ''(to Marlin)'' Mr. Fish, did you die?\\
'''Dory''': Sorry. I was a little vague on the details.
* DistressedDude: Nemo, who is captured at the beginning and trapped in an aquarium for most of the film.
* TheDitz: Dory, ''in spades''. Also, to a lesser extent, Deb.
* DoesThisRemindYouOfAnything:
** The group of sharks who have sworn off eating fish is played as if it were an Alcoholics Anonymous meeting or similar drug rehab group, complete with pledge ("Fish are friends, not food"), 'steps' and interventions if one of the members has / looks like they're going to fall OffTheWagon
* DownerBeginning
* DumbBlonde: Inverted with Dory, as in-universe, being blue is the equivalent of being blonde. She even mutters "I'm a natural blue" in her sleep.
* DVDCommentary: While the audiovisual commentary track was an interesting concept, by the time you get to the second or third behind the scenes segment interrupting the movie you can see why future films do not use the technique.
** They do it better in the Blu-Ray edition of ''WesternAnimation/ToyStory 3'', where the video actually stays in the frame in a picture-in-picture.
* EarlyBirdCameo: Luigi from ''WesternAnimation/{{Cars}}'' makes a brief appearance when the aquarium fish are escaping. The boy in the waiting room on Escape Day is reading a [[WesternAnimation/TheIncredibles Mr. Incredible]] comic. [[MonstersInc Mike]] swims by during the closing credits.
* EarWorm: [[invoked]] "Just keep swimming, just keep swimming!" Marlin gripes that it's going to be stuck in his head.
* EasyAmnesia[=/=]LaserGuidedAmnesia: [[AvertedTrope Averted]] for the most part. With a few plot-important exceptions, Dory suffers from fairly plausible amnesia, of some combination of anterograde (i.e. new memories are not processed) and retrograde (i.e. old memories are lost). Well, at least plausible [[RuleOfFunny by the standards of a children's film]].
** Apparently, psychologists and neurologists say it's [[ShownTheirWork the most accurate portrayal of real amnesia in film]].
* EitherWorldDominationOrSomethingAboutBananas: "He either said to move to the back of the throat, or he wants a root beer float."
* ElectricJellyfish: While no electrical energy is actually seen, the jellies make electrical crackling and zapping sounds when they sting.
* EmpathicEnvironment
** During happy scenes (e.g. Coral and Marlin discussing their eggs), the water is a beautiful clean blue.
** When Marlin [[spoiler:has crossed the DespairEventHorizon]], the sky is cloudy and the water is murky and dark.
* EmptyPromise
* EruditeStoner: Crush.
* [[ThreateningShark Everything Is Even Worse With Sharks]]: [[SubvertedTrope Luckily,]] the sharks seen here have sworn off fish.
** Until Bruce [[DoubleSubversion gets a noseful of Dory's blood and goes]] ''[[DoubleSubversion berserk]]''. His friends still tried to stop him, though.
* ExplainExplainOhCrap: "Good morning, everyone! Today's the day! The sun is shining, the tank is clean and we are getting out of-- (gasp) ''the tank is clean.'' '''The tank is CLEAN!'''"
* FaceOfAThug: The sharks, especially Bruce. Subverted that Bruce becomes dangerous if he smells blood.
* FamedInStory: The story of Marlin's quest to find his missing son becomes legend, and Marlin himself is elevated to the status of folk hero.
* FeatherFingers: Nigel. And, of course, virtually every character has fin fingers.
* FiveManBand: The Tank Gang.
** TheHero: Gil
** TheLancer: Gurgle
** TheBigGuy: Bloat
** TheSmartGuy: Peach
** TheChick[=/=]TeamMom: Deb
** TheHeart: Bubbles
** SixthRanger: Nemo
** TeamPet: Jacques
* ForebodingFleeingFlock: Dory and Marlin are arguing that it's just as good the whale they were trying to talk to swam away, since he might have been hungry. Dory counters that whales only eat krill. Cue a cloud of krill swimming past them with a whale's open maw right behind them.
* ForeignExchangeStudent: Squirt the baby sea turtle becomes one at the end of the movie.
* FreezeFrameBonus: During Gil's ImagineSpot on their escape plan, one of the cars driving by is the Pizza Planet truck from ToyStory. Continuing their tradition of putting it in every Pixar movie.
** One of the other cars that pass is an early version of Luigi from ''WesternAnimation/{{Cars}}''.
* FunWithFlushing: Nemo's escape plan is to play dead and get flushed, because "all drains lead to the ocean". Many have pointed out that in reality, a fish would not survive the trip, as it would be ground up during the sewage treatment process, leading some to joke that the title should have been "Grinding Nemo".
** Being Pixar, the creators had in fact painstakingly researched the Australian sewer system in order to show Nemo avoiding the perils therein, but the sequence was cut for time.
* FurryReminder: "[[BringMyBrownPants You guys made me ink]]."
* GeniusDitz: Dory, who knows how to read humans writing and understands whale language and knows about whales in general. "Don't worry, whales don't eat clown fish, they eat krill."
* GenkiGirl: Dory whose perkiness and high energy buoy all her friends in rough times, or just annoy them.
* GenreBusting: It's a road movie/coming of age/thriller/animal comedy/prison escape/surf movie.
* GentleGiant: Bruce and the whale.
* GettingCrapPastTheRadar:
** Deb introduces herself as "your aunt Deb", then introduces her "sister", Flo, making her Aunt Flo
** A non-sexual example: the name of the aquarium mountain is called Mount Wannahockaloogie.
** While watching the closing credits roll upward, Dory gasps in horror at the word "flocking".
** '''Jacques''' "Aughh!! Don't you guys realize we're swimming in our own--"
--> '''Flo''' "Shhh! Someone's coming!"
* GirlishPigtails: Darla
* GoodScarsEvilScars: Gill has extensive scarring on the right side of his body, mostly over his face (but [[EyesAreUnbreakable leaving his right eye intact]]) and his right fin (now as useless as Nemo's one) from a failed escape attempt, adding to his grizzled, fierce personality.
* GossipEvolution: How the news of Marlin's adventure gets around - by the time the news reaches Nemo, he sounds considerably more {{Badass}} than he really was. For example, he scared away the three sharks when Dory accidentally launched a torpedo. Nigel reports that he "blew them up".
* GratuitousFrench: Jacques, the shrimp who speaks almost nothing but French. First time you see him, a stereotypical little accordion ditty plays. The one exception counts as GratuitousEnglish: when Jacques is leading Nemo to his induction into the Tank Gang, he at first says "Survez moi", which Nemo doesn't understand, so he has to repeat it in English: "Follow me".
* GrillingTheNewbie: The other fish in the tank ask Nemo endlessly about the Ocean.
-->'''Bubbles:''' "The old big blue, eh? What's it like?
-->'''Nemo:''' "It's...[[ShapedLikeItself big and blue]]."
-->'''Bubbles:''' "I ''knew'' it!"
* GuileHero: Gill is somewhere between this and a protagonist MagnificentBastard, even though his plans (almost) always fail. He's atypical in that he appears somewhat uncomfortable in this role: he has a HeroicBSOD after [[spoiler: Nemo almost gets filleted by the tank filter while partaking in one of his plans.]]
* FunnyBackgroundEvent: There are actually quite a few. A good one is when Marlin is trying to tell his joke at the start. Nemo at first has an 'Oh, boy' expression, then an embarrassed and apologetic smile.
** A meta example occurs on the 2-disc DVD introduction: whilst Andrew Stanton and Lee Unkrich are talking about the included bonus features, in the background you can see John Lasseter waving and then miming diving over a rail.
* HandicappedBadass: Gill. Extensive scarring on his right fin makes it as useless as Nemo's atrophied one. That doesn't prevent him from being a sort of mentor to Nemo.
* HoldYourHippogriffs:
-->'''Gill:''' It'll be a piece of kelp.
* HollywoodDarkness: Averted in the trench scenes, which are absolutely pitch black until the anglerfish arrives. Played straight in the whale's mouth.
* HollywoodDensity: In the final scene where the aquarium fish finally escape, the water in their bags somehow floats above other water in the ocean.
** [[AvertedTrope Nothing wrong here.]] Remember, the bags also contain an air pocket at the top.
*** Furthermore, the bags contain warm water from a temperature-controlled tank. It's likely that the water was warmer than the seawater in the harbour, and thus less dense.
* HopeSpringsEternal: After they have escaped from a hungry shark and massive minefield explosions, Marlin and Dory are exhausted. Marlin is anxious to find his missing son, Nemo, but now he has lost his best clue for finding him — a scuba mask inscribed with the address of the diver who captured Nemo. Dory helps Marlin find hope. Discouraged, Marlin says, "That was my only chance at finding my son; now it's gone!" But Dory is not so easily deterred. "Hey, Mr. Grumpy Gills," she says. "When life gets you down, you know what you gotta do? Just keep swimming, just keep swimming, just keep swimming, swimming, swimming. What do we do? We swim, swim."
* HumansAreCthulhu
* HumansAreMorons: More like "A Human Dentist is Misguided And His Niece Needs To Look Up What Happens When You Shake A Fish Bag."
* IgnorantOfTheCall: Marlin thinks of himself as just a father who is desperately trying to recover his missing son. To Dory, and Nemo, the sea turtles, Nigel the Pelican, the fish in Dr. Sherman's tank, and many, many others, Marlin is a {{Badass}} [[TheDeterminator determinator]] who repeatedly triumphed over unbelievable odds.
* InnocentInnuendo: "I'm gonna go touch the butt!"
* InterspeciesFriendship: Not only do different kinds of fish get along, but they also befriend sea turtles, and even species that otherwise prey on fish, such as sharks and pelicans.
* ItsAllMyFault
* KeepAway: Around the beginning of the film, a couple of the kids in Nemo's class pull this on another kid.
* LandDownUnder
* LawyerFriendlyCameo: "The Prime Minister" makes a brief appearance as one of Dr. Sherman's patients. [[note]]For the record, the Prime Minister at that time would have been John Howard.[[/note]]
* LethallyStupid: Darla is actually a relatively normal girl (except for the braces), what makes her an antagonist is her bad habit to shake her fishes like crazy.
* LightIsNotGood: The anglerfish's light may look inviting but it leads to frightening teeth.
* LivingEmotionalCrutch: Marlin to Dory. Being with him somehow cures her amnesia.
** And the other way around, as Dory's optimism, easy-going nature and encouragement helps rein in Marlin's neurotic side and keep him focussed.
* LocalReference: Director Andrew Stanton is from Rockport, Massachussetts, so he included several references to it, including lamp replicas of two lighthouses in nearby Thacher Island and a photograph of "Motif Number One", a local landmark, as well as lobsters with thick "Bahston" accents and local slang ("Wicked").
* LopsidedDichotomy: Dory translating whale speech:
-->"Okay, he either said, 'move to the back of the throat,' or he 'wants a root beer float'."
* TheLostLenore: Coral and most of their children.
* {{Keet}}: Nemo on a good day. The baby sea turtles also count.
* ManicPixieDreamGirl: Dory to Marlin.
* MeaningfulBackgroundEvent: The whale and jellyfish.
* MeaningfulEcho: Lots. It is a {{Pixar}} film, after all.
** "All drains lead to the ocean."
** "Keep swimming," and "Swim down."
* MeaningfulName:
** A dory is a small fishing boat.
** The Mako shark is named Chum.
** Bruce is both the stereotypical term for any Australian male, and the nickname given by the ''{{Film/Jaws}}'' team to the mechanical shark they used.
** Nemo is the name of the famous undersea captain in ''Literature/TwentyThousandLeaguesUnderTheSea''. It's also the name of [[ComicStrip/LittleNemo a little boy who goes on fantastic dream adventures]].
* MemeticBadass: Marlin ends up as one in-universe as tales of his journey filter through the ocean and become larger than life.
* MindControlEyes / MonochromaticEyes / BlackEyesOfEvil: When Bruce the shark accidentally gets a whiff of blood.
* MobileFishbowl: In TheStinger Gill, Deb and the other captives in the dentist's fish tank use the fact that they've been put in clear baggies of water while the tank is being cleaned to make their escape to the sea. This involves bopping the baggies forward through a building and across a busy roadway. [[spoiler:Good news: they succeed. Bad news: they have no idea how to get out of the baggies.]]
* MonstersAnonymous: The shark's support group.
* MoodWhiplash:
** Before and after the opening titles.
** "Good feeling's gone."
* MyGodWhatHaveIDone: Gill, upon realizing he selfishly risked Nemo's life for his own means.
* NeverHeardThatOneBefore: Jokes about Marlin being a clown fish.
* NoCartoonFish: Aversion.
* NonSequiturThud
* NoodleIncident: "Hey, that snail was about to charge."
* ObliviouslyEvil: Darla and the dentist
* SuperOCD: Gurgle is perhaps the definition of this trope. When he learns that Nemo is from the ocean he immediately gets Jacques to clean him. Also is visibly shaking and really nervous when the tank is really dirty for their escape plan, finally snapping and exclaiming
--> '''Gurgle:''' DO YOU REALISE WE ARE SWIMMING IN OUR OWN-
--> '''Peach:''' Shhhh!!!!
** While watching a patient spitting out some mouthrince into a cup
---> "Ugh, the human mouth is a ''disgusting'' place....
* OhCrap:
** Bruce's first appearance.
** Bruce [[UnstoppableRage smells]] [[BerserkButton blood.]] [[YouShallNotPass "INTERVENTION!"]]
** Later at the end of scene, [[SeaMine just where the torpedo is going...]]
** Jellyfish area.
** Getting gulped by the whale. [[spoiler: Fortunately, he was just giving them a ride to Sydney Harbor.]]
** "Good feeling's gone."
** "Mine?"
** "THE TANK IS CLEAN!"
** Everyone yelling, '''''"DARLA!"'''''
* OminousLatinChanting: Not in Latin, and (except possibly to the very youngest viewers) not all that ominous. Arguably a parody.
* OnlySaneMan: Marlin and Gill, compared to their respective companions.
* OrphanedPunchline: Marlin proves that, despite what all the other fish think, not all clown fish are funny.
** One of the bonus features of the DVD are 10-15 different punch lines that were considered for the closing scene. Good times, good times.
* PapaWolf: Marlin. Shark, anglerfish, jellyfish, pelican, human... He will topple the food chain to get his son back.
* ParentalBonus:
** The sequence with the vegetarian sharks is an obvious reference to AA meetings.
** After Nemo jams the filter: "Everybody else, be as gross as possible. Think dirty thoughts. We're gonna make this tank so filthy the dentist will HAVE to clean it."
* ParentalSubstitute: Gill acts as something of a surrogate father to Nemo while in the tank.
* PleaseDontLeaveMe: Dory to Marlin.
* PlotTriggeringDeath: In a rather roundabout example, Coral's. Her death happens some years before the actual story, but hadn't it been for that, the plot wouldn't have happened, at least not the way it did.
* PortmanteauCoupleName: Dorlin for Dory/Marlin.
* PsychoStrings: Played whenever Darla looks at the camera.
* PunctuatedPounding: A rare example of the dialog and pounding coming from different characters:
** '''BANG''' Sorry about '''BANG''' Bruce, mate! '''BANG''' He's really '''BANG''' a nice guy!
** I have to get out of here! '''BANG''' I have to find my son! '''BANG''' I have to tell him how! '''BANG''' old! '''BANG''' sea! '''BANG''' turtles! '''BANG''' are! '''BANG'''
* TheQuest. And while it's not a perfect [[TheSevenBasicPlots Booker's Quest]], it does meet plenty of the specifications: Monsters (angler fish), Temptations (Bruce delays then, when they get back on track, turns deadly), Dangerous Terrain (mines, jellyfish), Deadly Opposites (Marlin even ignores the guides!), the Journey to the Underworld (the whale), then the halfway arrival where the heroes realize the task is even harder than imagined. Not to mention Dory's role as Anima and how ''she'' is the one who first connects with the prize.
* ReallySevenHundredYearsOld: Crush is 150, and still young, dude.
* RidiculouslyCuteCritter: Nemo and the baby sea turtles.
* RoadMovie: An inversion: it's underwater so there aren't any roads.
* RousseauWasRight: Nobody's really evil in this film. The barracuda at the beginning, the [[AlluringAnglerfish angler fish]] and the [[FunnyMoments seagulls]] are just [[CarnivoreConfusion hungry]]; Darla, being a relatively normal kid, is completely [[ObliviouslyEvil oblivious]] to the fact that she's a fish-killer; the jellyfish are just, well, jellyfish; the dentist thinks he's saving Nemo due to him seeing his lucky fin; and the [[EverythingsEvenWorseWithSharks sharks]] are actually [[NiceGuy Nice Guys]].
* RuleOfCool:
** Turtles don't actually travel in groups, but in the words of Stanton himself, "But it was just too cool and it helped the story along. We don’t address it in the script, but they’re all off to Hawaii to go surf.”
** Also, lobsters with Bostonian accents near the Australian Coast.
* TheRedStapler: After the release of this movie, kids wanted clownfish and others seen in the movie. Ironic, considering half the movie involves Nemo wanting to ''escape'' life in a tank.
* SavvyGuyEnergeticGirl: Marlin and Dory. One is grumpy and grounded while the other is perky and optimistic pushes him forward.
* ScarsAreForever: The ones on Gill's face that he apparently got from trying to escape the tank.
* SeaMine: A whole minefield of them too.
* ShipTease: Dory and Marlin.
* ShortCutsMakeLongDelays: Marlin swimming over the scary-looking trench rather than through it leads to an encounter with jellyfish.
* ShoutOut:
** When the moonfish form the shape of a sailing ship, they start singing "[[Film/TwentyThousandLeaguesUnderTheSea Got a whale of a tale to tell you, lads...]]"
** "[[Film/TheShining Heeeeeeere's Brucie!]]"
** [[Film/MontyPythonAndTheHolyGrail "Swiiim awaaay!"]]. Also ''several'' others.
*** Speaking of Creator/MontyPython, there's an added joke about a character named Bruce having an Australian accent.
** Bruce was [[FanNickname the nickname]] Spielberg gave [[Film/{{Jaws}} the animatronic shark]], [[IAmNotShazam though not the name of the shark itself]].
*** And the torpedo sliding into his mouth is reminiscent of [[spoiler: the shark in Jaws with the air tank in his mouth]]
** The PsychoStrings and the gulls surrounding Nigel, Dory and Marlin like a certain scene in ''Film/TheBirds''...and it's been said Pixar don't reference other movies!
** There's also P. Sherman's address, [[Franchise/TheHitchhikersGuideToTheGalaxy 42]] [[Franchise/WallaceAndGromit Wallaby Way]].
** Doubling as an ActorAllusion, [[http://www.premiere.com/var/ezflow_site/storage/images/media/images/finding-nemo-gil/657184-1-eng-US/finding-nemo-gil.jpg Gill's scars]] are almost identical to the ones [[http://www.cinemovies.fr/images/data/photos/G38072144681843.jpg Tom Berenger]] sported in {{Platoon}}.
** Pearl, Nemo's little octopus schoolmate ("You guys made me ink!") bears strong resemblance to Pinky the ghost from Pac-Man. Ditto for her dad.
** While excaping from Bruce, Dory sees a sign labeled "escape" [[AChristmasStory and pronounces it as "es-ca-pay."]]
** At one point, Nigel refers to the dentist as "Diver Dan" - a reference to Australian dramedy Sea Change.
** In the process of getting Nemo's name wrong, Dory names at least two of TheMarxBrothers - Chico and Harpo.
** In an odd sort of ThemeNaming, Crush and his son Squirt are named after fruity soft drinks.
** There's a boat in the Sydney harbor in named "iBoat" in homage to Creator/{{Pixar}}/Apple CEO Steve Jobs.
* ShownTheirWork: The entire Pixar staff had to take a graduate class in fish biology before making the movie.
* SimultaneousArcs: Most of the movie splits between Marlin in the ocean and Nemo in the tank.
* SmallTaxonomyPools:
** Largely played straight. Among fish we see colorful reef-fishes, and then the stock seahorses, puffers, rays, great white and hammerhead sharks, and barracudas (will we ever see an ocean sunfish, dolphinfish, pipefish, and remoras in fiction?). The sea birds are gulls and pelicans (and what about frigatebirds, tropicbirds, skuas and so on?); the sea-mammal is a whale, the sea-reptiles are the classic Chelonid turtles: and we have crabs, jellyfishes and starfishes as the invertebrate members of the fauna.
** But it's averted as well: this is perhaps the first time a deep-sea fish shows up in a relevant role in Fictionland (the anglerfish). Not only that, many sea creatures from RealLife are [[GeniusBonus well recognizable by who knows]]. The whale isn't the stock generic large cetacean, it's quite ''specifically'' a blue whale. Tropical fish pertain to precise species (clownfish, blue tang, moorish idol, ''Gramma loreto'' and so on); one of the three sharks is a Mako; and the hero is called ''Marlin'' (the latter is lampshaded by Nigel trying to remember Marlin's name and saying "[[LampshadeHanging It's some kind of sport fish or something...]]" at one point). The chosen cephalopod is the unconventional "Dumbo-octopus". Finally the (totally unexpected) krill: ''talking krill''!
* TheSmurfettePrinciple: The film has 9:3 male-to-female ratio. The writer explains on the DVD commentary that in fact ''Dory was originally male'' until he saw Creator/EllenDeGeneres on television and realised that was the sweet-but-scattered tone he was looking for.
* SomethingThatBeginsWithBoring: Dory and Marlin.
* SomewhereAMammalogistIsCrying: A [[GentleGiant friendly blue whale]] gives Marlin and Dory a ride for protection, before sending them on their way by forcing them to the back of its throat to eject them out of its blowhole. Marlin fears they'll be devoured, whereas Dory tells him to trust their giant friend. Marlin, however, was absolutely ''correct''. A Blue whales' esophagus and wind pipe ''are not connected''. By all accounts if forced down its throat they should have been [[SwallowedWhole swallowed alive]].
* SoWhatDoWeDoNow: Gill and the rest of the aquarium fish at the end.
* SpeechImpediment: Darla has trouble speaking with those terrible braces.
* SpellMyNameWithAnS: Is Gill's name spelled with one or two L's?
* StaringKid: The kid in the dentist's waiting room who reacts with horror at the commotion.
* StealthPun:
** Nemo attends a school of fish.
** Crush mentions that "Mr. Turtle" is his father. That would make his name Crush Turtle...or C. Turtle.
* TheStinger: In the last scene before the credits, see all the fish from the dentist office after their successful escape [[spoiler: still stuck in their plastic bags since their plan never got that far]].
-->'''Bloat:''' [[AndThenWhat ...now what?]]
** [[spoiler: Though they're all okay in the end credits]].
* SuddenlyBilingual: Dory, who apparently can read Spanish as well as English (and speak Whale).
* SurferDude: Crush, and the turtles. Apparently, ''all'' of them.
** Crush is 150 years old, it's not like he needs to do anything in a rush.
* SurvivalMantra: Many. The most famous one is 'Just keep swimming', but Marlin deliberately invokes it in one scene while playing it straight for himself. When Dory gets hurt in the Jellyfish fields, he makes Dory repeat where P. Sherman lives, while repeating 'Stay awake!' to himself.
** "Swim down!" When Nemo is netted in the aquarium and again when the school of fish is caught. Also counts as ChekhovsSkill.
* [[SuddenlyFluentInGibberish Suddenly Fluent in Whale]]: Marlin is less then impressed by Dory's claims to be able to to speak whale, especially since it consists entirely of talking really slowly. Somehow, it works. And then Marlin imitates her.
-->'''Dory:''' Wow. I wish I could speak whale.
* SwallowedWhole: ''Twice''. The pelican's case is possible, but the whale's isn't.
* SynchronizedSwarming: A swarm of fish does a series of impressions for Dory and becomes an arrow to give her and Marlin directions to Sydney.
* [[TakeMyHand Take My Fin]]: Possibly inverted.
* TemptingFate:
--> '''Nemo''': Have you ever met a shark?
--> '''Marlin''': No, and I don't plan to.
** "If I ever meet a [[ReallySevenHundredYearsOld turtle]] I'll ask him... [[{{Foreshadowing}} after I'm done talking to the shark.]]"
* TheyCallMeMisterTibbs: Type 2 - "Please, Mr. Turtle is my father, the name's Crush."
* [[ThisIsYourBrainOnEvil This Is Your Brain On Fish Meat]]: The sharks.
* ThoseTwoGuys:
** Anchor and Chum.
** Partially subverted with Gerald (the pelican that tried to swallow Dory and Marlin) and Nigel, who obviously knows him far too well. They were originally supposed to be ThoseTwoGuys, but most of Gerald's scenes were cut.
* TheToothHurts: The scene where the dentist is trying to remove the prime minister's tooth. When Nigel the pelican runs into the window, the noise startles the dentist so much that he forcefully pulls out the bad tooth, putting the prime minister in a lot of pain.
* TrailersAlwaysLie: A popular scene shown in the commercials was Bruce swimming through some seaweed while saying "We're looking for Nemo!" This was never used in the movie. In fact, the super hyped up sharks in the trailers were just [[OneSceneWonder One Scene Wonders]].
* TropaholicsAnonymous: The sharks
* TruthInTelevision: Yes, Jellyfish really DO travel in big swarms like that.
** Averted with the turtles; they do not. Andrew Stanton admitted it worked for the story.
* TurtlePower: Crush, Squirt, and the other sea turtles of the EAC are all [[SurferDude awesome.]]
* UnusualAnimalAlliance: Sharks attempts such an alliance with fish, and have support meetings complete with the mantra:
-->Fish are friends, not food!
* VerbingNouny
* VerbalTic: Crush has one, dude.
* WakingNonSequitur: After the incident with the sharks, Dory wakes up screaming "Look out! Sharks eat fish!" She also has "Zzz... the sea monkeys have my money... Mmm... yes, I'm a natural blue..."
* WasTooHardOnHim: What Marlin feels about Nemo.
* WaterIsAir: Averted.
* WhatMeasureIsANonCute: The good guys are colorful tropical fish. They're threatened by ugly, drably-colored predators with sharp teeth who don't talk. And then there's the sharks, [[CarnivoreConfusion who try to go vegan]], [[OffTheWagon but old habits die hard]]. Interestingly, they ''do'' reference the hypocrisy of humans who think dolphins are cuter than sharks.
* WhatsAnXLikeYouDoingInAYLikeThis: "What's a couple of bites like you doing in a zone like this?"
* WhereItAllBegan: It ends in the reef, with the characters doing the same things they did in the first scene, only differently, reflecting how the moral has changed them.
* WhiteAndGreyMorality: All the villains (Bruce and the humans) are trying to reform or misguided. There's also the jellyfish and seagulls, which are apparently too stupid to be evil. The barracuda and the anglerfish, although both vicious killers, are really just hungry by nature. Overall, this movie's villains are much milder than those of other Pixar movies.
* WhoNamesTheirKidDude
-->'''Marlin''': So, Mr. Turtle...
-->'''Crush''': Woah, dude, [[DontCallMeSir "Mr. Turtle" is my father]]. Name's Crush.
-->'''Marlin''': Crush? Really?
* TheWindowOrTheStairs: Dory and Marlin come across a chasm. Dory was told that they had to go through it, and she tries to tell Marlin, who ignores her and then tricks her into swimming over it, since it seems much safer. They [[spoiler:end up in a huge swarm of jellyfish, and they both almost die because of the stings]].
* WolverinePublicity: Bruce (the shark) and Crush (the sea turtle) were both heavily promoted and feature on the movie posters and home video covers. They respectively only appear in no more than [[OneSceneWonder two scenes a piece.]]
* YouHadUsWorriedThere: When Nemo jams the filter, [[spoiler:the second time]].
* YouSayTomato: According to [[TheGhost Sandy Plankton]], a boat is called a "butt.", although Nemo's friends could just be misquoting him.
