->'''Donnie:''' Why are you wearing that stupid bunny suit?\\
'''Frank:''' Why are you wearing that stupid man suit?

A cult MindScrew film, set in October 1988, about a schizophrenic teenager called Donnie Darko (Creator/JakeGyllenhaal) who sees a demonic rabbit figure named "Frank" while sleepwalking. Frank tells him that the world will end in 28 days, just before a jet engine crashes into Donnie's bedroom. Donnie credits Frank with saving his life by causing him to sleepwalk out of the house, and begins to do Frank's bidding, while gradually trying to uncover the strange events around him which [[MindScrew may or may not]] be related either to TimeTravel, an [[AnotherDimension Alternate Dimension]], or Donnie's worsening [[TheSchizophreniaConspiracy Schizophrenia]].

A [[DirectorsCut director's cut]] version was constructed by the author Richard Kelly several years after the original release. It greatly alters the pacing of the movie by the addition of deleted scenes, new digital effects and soundtrack alterations. The author considers this version not a director's cut but rather an "extended special edition". Fan opinions are somewhat divided as to which version is better.

Rumors of [[SDarko a sequel]] have been [[FanonDiscontinuity vehemently denied by fans for years]].

!!This film includes examples of:

* ActuallyPrettyFunny: Debatable. Donnie's father, Eddie Darko, chokes out a chuckle at the "he told me to forcibly insert the lifeline exercise into my anus" line. However, he's actually rather crass for an 80's dad, if the opening montage where he blasts Elisabeth with a leaf blower didn't already clue you in.
* AlliterativeName: Donnie Darko.
* AllThereInTheManual: The book ''The Philosophy Of Time Travel'', alluded to in the theatrical version and quoted briefly in the DirectorsCut explains the plot (or at least the [[WordOfGod Director's interpretation]] of it) and removes all the ambiguity with a lot of hand-holding.
* TheAntiNihilist: Arguably, Donnie. His whole life seems to be one big, cruel cosmic joke. No matter what he does, he's apparently condemned to repeat the same loop over and over again... [[spoiler: unless he kills himself beforehand.]] Meanwhile, his school life is spent constantly at odds with crusading teachers and motivational speakers. Yet this doesn't stop him from enjoying things while they last, and in his final scene, [[spoiler: before getting crushed by the jet engine,]] Donnie just... laughs.
* AtomicFBomb: After Donnie's English teacher [[spoiler:loses her job]], she runs outside the school and screams "FUUUUUUUUUUUUUUCK" at the top of her lungs.
* TheAtoner: Arguably [[spoiler:Frank. His actions in helping Donnie seem to be his way of making up for accidentally killing Gretchen- and eventually preventing her death from occurring in the first place.]]
* AuthorAvatar: Richard Kelly describes the nameless kid who shows up at the end of the film as this.
* AwesomeMcCoolname: Discussed.
-->'''Gretchen:''' What kind of name is 'Donnie Darko', anyways? It sounds like a [[StevenUlyssesPerhero superhero name]].
* AxeCrazy: [[MeaningfulName Seth Devlin]] is one of the more perfect examples of this trope, actually.
* BigShutUp: Poor old Cherita Chen yelling "[[VerbalTic CHUT UP]]" at Donnie after he tells her that [[spoiler:things will get better]].
* BittersweetEnding: [[spoiler:If you think about it, the whole movie is this. Donnie would have died outright had Frank not spoken to him and gotten him out of bed: thus the entire rest of the movie. The whole purpose of the film seems to be allowing Donnie to come to terms with his premature death, and to realize that sad as it is, it's way better than the alternative of the world ending.]]
** Though it may be a ShootTheShaggyDog, depending on whether you understand the foretelling to mean [[spoiler:"You need to have completed [[StableTimeLoop the cycle]] or ''everything'' would have gone kablooie." Or possibly, to mean [[AlternateTimeline that]] world or Donnie's DeadlyEuphemism world]].
** DownerEnding: One interpretation makes it this, though not in the way it seems to be: [[spoiler:The end of the world Frank was talking about was actually the end of the time loop, meaning that the events of the film will continue to repeat over and over again, with different variations each time. This literally ends the universe, as time will never advance beyond the appearance of the portal. By dying, Donnie has only created another variation, and he'll be alive again the next time the world resets, making the ending comparable to Film/{{Memento}}]].
* BlackAndWhiteMorality: The Life Line scene (see Crowning Moment of Awesome) has the teacher arguing this (Fear vs. Love), while Donnie asserts that the world revolves around GreyAndGrayMorality.
* BlueAndOrangeMorality: Another interpretation of the Life Line scenes are that the teacher is trying to assign all things a moral weight based on their positions between Fear and Love as opposed to a broader worldview which includes not only traditional moral concepts such as right and wrong as well as other emotional components such as greed, joy, anything, not simply things that are sourced in Fear or Love.
* BreakTheMotivationalSpeaker: Donnie undermines Cunningham's methods, attacks his very simplistic "fear vs. love" spectrum and eventually calls him "the fucking Antichrist". It turns out that [[spoiler:the guy is a kiddie porn enthusiast, so Donnie was sort of right]].
* ButterflyOfDoom: Take your pills one night, doom the universe.
* ByronicHero: Donnie Darko, himself.
* CaughtWithYourPantsDown: Donnie ''almost'' starts masturbating during a hypnotherapy session.
* CheshireCatGrin: the expression on Frank's mask is a rather disturbing parody of a cutesy buck-toothed rabbit.
* CloudCuckooLander: Donnie. He could also be interpreted as a Deconstruction, as his behavior has him sent to counseling and diagnosed with schizophrenia, as well as the isolation leading him to violent behavior in his youth and adolescence. [[TheCuckoolanderWasRight However,]] [[TheSchizophreniaConspiracy There's a possibility that he's not even one of these at all...]]
* CrapsaccharineWorld: The seemingly idyllic StepfordSuburbia slowly unravels over the course of the film. One of the arguments for starting the film ''without'' "The Killing Moon" is that it allows things to seem much more normal at first and gradually get twisted as the month goes on.
* DeusExMachina: {{Lampshaded}} when Donnie murmurs this as Frank arrives to solve (sort of) everything.
* TheEighties:
** Complete with a TV debate between George H. W. Bush and Michael Dukakis.
** WordOfGod says that it was set in TheEighties because that's when Richard Kelly grew up and he wouldn't be able to write a coming of age story in the 2000's due to lack of frame of reference.
* EvilLaugh: After Frank is killed, a shot of his mask on the ground pitching slightly back and forth in the wind conveys this trope very well.
* FauxHorrorFilm: This movie was marketed in every way as a straight horror film instead of the dream-like, supernatural [[MindScrew mind-screwy]] coming of age high school movie it is. It's creepy, but never really horror.
* FiredTeacher: Ms. Pomeroy.
* FlashSideways: As suggested by the hand waving in the last scene, some characters retained vestigial memories of the parallel timeline.
* FunnyForeigner: Cherita Chen has an accent that doesn't exactly match her (presumably) Chinese heritage, and is bullied.
* TheFundamentalist: Ms. Kitty Farmer, the school' crusadingly Puritan teacher.
** Jim Cunningham seems to be one at first, but then he's revealed to be merely a hypocrite [[spoiler: and paedophile.]]
* GainaxEnding: And beginning. And middle. Really, it should just be called "Gainax Ending: TheMovie"
* GoshdangItToHeck: Mrs. Farmer doesn't swear; when Donnie is sent to the principal's office after snapping at her, she claims that "he asked [her] to forcibly insert the lifeline exercise card into [her] anus!"
* HairRaisingHare: Frank.
* HeroicSacrifice: [[spoiler:Donnie chooses an unpleasant death in order to save everyone else.]]
* IconicOutfit: Donnie's skeleton outfit.
* InnocentSwearing: "What's a fuckass?"
* KarmaHoudini:
** [[spoiler:Jim Cunningham is a pedophile with a large stash of child pornography in his mansion which is discovered. In his final scene it sure looks like he's on the frayed end, however, due to the paradox causing it never to happen, nobody finds out that he is a pedophile]]. This is just invoking DeathOfTheAuthor, however, as...
** WordOfGod confirmed that he got caught on the day after Donnie would have [[spoiler:burnt down his house]]. It also says that [[spoiler:he commits suicide out of self-loathing]] not long after his vague dream-recollections of the Tangent Universe.
** It's because of Seth and Ricky's [[spoiler: bullying that Gretchen gets run over by Frank]], yet we don't see them get any comeuppance at all.
* KillerRabbit: Not really, but close.
* MentalTimeTravel: Suggested in the epilogue.
* MindScrew: For your sanity, [[BellisariosMaxim we recommend that you do not try too hard to make sense of the plot.]]
* MoralGuardians: Mrs. Farmer
* OneWomanWail: "[[http://www.youtube.com/watch?v=4TNQdwL9o1E The Portal (For Whom The Bell Tolls)]]"
* OnlySaneMan: Elizebeth, Cherita, Gretchen Ross, Rose, Dr. Thurman, Dr. Monnitoff, Mrs. Pomeroy and even Donnie to an extent.
* PowerHair: Ms. Farmer. Only scene (not including the end) when she doesn't sport it, she's at the end of her rope.
* PortalToThePast:
** Frank is capable of opening these.
** [[spoiler:So is Donnie, by the end.]]
* PrecisionFStrike: "What's a fuck-ass?" and "...I think you're the fucking Antichrist."
* PsychoticSmirk: When Frank gives him orders, Donnie's expression changes to one of these.
* RecycledINSPACE: [[spoiler:TheLastTemptationOfChrist]] WITH SCI-FI METAPHYSICS!
* SanitySlippage: The whole movie is about this. [[MindScrew Maybe]].
* TheSchizophreniaConspiracy: Donnie's psychiatrist suggests that his paranoia is caused by his schizophrenia. To be fair, she brings up the ''hallucination of a giant talking bunny rabbit'' first to justify her diagnosis.
* SeinfeldianConversation: While Donnie and his friends are drunk...
-->'''Sean:''' We gotta find ourselves a Smurfette.\\
'''Ronald:''' Smurfette?\\
'''Sean:''' Yeah, not some tight-ass Middlesex chick, right? Like this cute little blonde that will get down and dirty with the guys. Like Smurfette does.\\
'''Donnie:''' Smurfette doesn't fuck.\\
'''Sean:''' That's bullshit. Smurfette fucks all the other Smurfs. Why do you think Papa Smurf made her? Because all the other Smurfs were getting too horny.\\
'''Ronald:''' No, no, no, not Vanity. I heard he was a homosexual.\\
'''Sean:''' Okay, then, you know what? She fucks them and Vanity watches. Okay?\\
'''Ronald:''' What about Papa Smurf? I mean, he must get in on all the action.\\
'''Sean:''' Yeah, what he does, he films the gang-bang, and he beats off to the tape.\\
'''Donnie:''' [shouts] First of all, Papa Smurf didn't create Smurfette. Gargamel did. She was sent in as Gargamel's evil spy with the intention of destroying the Smurf village. But the overwhelming goodness of the Smurf way of life transformed her. And as for the whole gang-bang scenario, it just couldn't happen. Smurfs are asexual. They don't even have... reproductive organs under those little, white pants. It's just so illogical, you know, about being a Smurf. You know, what's the point of living... if you don't have a dick?\\
'''Ronald:''' [pause] Dammit, Donnie. Why you gotta get all smart on us?
* SetRightWhatOnceWentWrong: In a particularly dark version of this, Donnie has to [[spoiler:let himself be impaled by debris from the falling jet engine]], as by not [[spoiler:dying when the engine hit the house]], Donnie has doomed the universe.
* ShoutOut: Many. Many. Many. Some that aren't referenced directly are:
** The whole "Sparkle Motion" subplot was a huge reference to Graham Greene when he was sued by Creator/ShirleyTemple's lawyers for libel when mocking her middle-aged admirers. He's often cited as one of the first to criticize the sexualization of children.
** If you haven't seen ''{{Harvey}}'' then much of the situational humor will fall flat. A [[InvisibletoNormals big white rabbit that no one can see]] as referenced by a hallucinating nice guy [[spoiler:and [[NotSoImaginaryFriend may or may not be real]] ]]
* SilentWhisper: Donnie walks up to Roberta Sparrow and she stands on tiptoe to whisper, [[spoiler:"Everything on this earth dies alone."]] Donnie's dad asks what she said and the scene cuts without revealing (until later). New viewers will almost always ask prior viewers what she said.
* SmallReferencePools: Most of the music in the film is NothingButHits, and as soon as TimeTravel is brought up, Donnie references [[Film/BackToTheFuture the infamous DeLorean]].
** Nothing but hits in 1988 would have been Def Leppard, Guns and Roses. Echo and the Bunnymen, The Church, And Joy Division are much more popular now than they were in the 80s, where they were at best MTV novelties in American suburbia at the time. It is notable that most of it, with the exception of 'Under the Milky Way" had been released several years before the events of the film, which would be realistic for the time.
* SurrealSymbolicHeads: Frank; see the cover above. It's the reason he is [[spoiler:initially mistaken for an hallucination]].
* StableTimeLoop: One exists entirely inside the alternate universe: [[spoiler:Frank saves Donnie from being killed so that Donnie can be there to send the engine back. Along the way Donnie shoots Frank in the eye and kills him. Frank's ghost, still in the bunny suit and still missing an eye, then travels back and saves Donnie, starting the loop over.]]
* TheresNoBInMovie:
** Donnie and Gretchen go to see ''The Franchise/EvilDead'' as a date movie (in a double feature with [[WhatDoYouMeanItsNotSymbolic ''The Last Temptation Of Christ'']], oddly enough).
** The director's first choice was ''Film/{{CHUD}}'', but there was a problem with the rights. Nevertheless, Donnie still compares Mr. Cunningham to a chud in one scene.
** Actually, the reference to "Last Temptation of Christ" makes sense, if you've seen the movie. First off, Donnie is essentially [[spoiler: a Christ figure who saves the world by sacrificing himself]]. Secondly, in Scorsese's film, [[spoiler: Jesus has an extended dream of an alternate life while he is dying on the cross. He must choose whether to live as a normal mortal man or to die to save everyone else--essentially the same choice Donnie had to make. The extended dream sequence is basically analogous to Donnie's time loop in that it gets reset at the end when Jesus chooses to die.]]
* ThrowItIn: Noah Wylie deciding his character was diabetic (watch for the Jolly Rancher candies).
* TimelineAlteringMacGuffin: The jet engine has caused a paradox by falling back in time which will destroy the universe unless it is dealt with.
* TomatoInTheMirror: Donnie is convinced that the gun he finds is the artifact described by The Philosophy of Time Travel, because the artifact must be made of metal. The film suggests that a Deus Ex Machina is necessary in order for a story to have a conclusion. The reality is that the Jet Engine that almost fell on Donnie Darko is the true artifact, that it will time-travel to the past and must land on Donnie Darko in order to save the future from his own actions. The Philosophy of Time Travel is a thinly veiled approximation to The Hero's Journey, from the work of Joseph Campbell; the artifact is introduced in order to serve the purpose of defeating the villain of the story, usually taking on the form of a weapon. Regardless of Donnie Darko's intentions (and the temporary positive results of his rebellion), the end results of his actions demonstrate to himself that he is not the hero he perceives himself to be, thus requiring the Deus Ex Machina to save the world from him.
* WhatYouAreInTheDark: [[spoiler:Donnie sacrificed his life to save the world, and no one will ever know.]]
