'''''Jennifer's Body''''' is an 2009 [[SlidingScaleOfComedyAndHorror Comedy Horror]] film written by Creator/DiabloCody, the writer of ''Film/{{Juno}}'', and starring Creator/MeganFox and Creator/AmandaSeyfried. Jennifer is a high school cheerleader who goes to a rock concert, where the band tries to sacrifice her to {{Satan}} in order to get a record deal. It works, but Jennifer gets possessed by a demon in the process, causing her to start seducing, killing, and eating the boys in her school. Upon finding out, Needy, Jennifer's "plain jane" best friend since childhood, sets out to stop her from wiping out the student body.

The name of the film is taken from the song "Jennifer's Body" by {{Hole}}. Oddly, the song does not appear in the film, although another track from the same album does.
----
!!This film has examples of the following tropes:
* AdrenalineMakeover
* AllGuysWantCheerleaders
* AlphaBitch: Jennifer was like this even before she turned into a demon. Needy just seems to be somewhat safe from her more overt {{jerkass}} tendencies.
* AnnoyingYoungerSibling: Chip's little sister Camille.
--> You're penis cheese!
* AssholeVictim: [[spoiler:Low Shoulder really had it coming.]]
* BaitAndSwitchLesbians: The earliest trailers showed Jennifer and Needy in intimate situations and despite their making out in the movie, both of them have male romantic/sexual interests. However, there is enough LesYay in the movie for someone to reasonably assume that the two girls were at least bisexual. The argument could even be made for Jennifer being an outright lesbian, since all of her male interests were either the result of jockeying for social position, or trying to keep Needy for herself. In fact, after a scene of Needy gazing a little too blissfully another girl says to her point blank: "You are totally [=LesbiGay=]."
* BigBadFriend: Jennifer. She even tries to stay "[[FriendlyEnemy friends]]" with Needy... kinda.
* BigNo: Needy, after [[spoiler:Chip's death]].
* BillingDisplacement: Perhaps one of the most extreme example ever. Creator/AmandaSeyfried, who is the film's protagonist and appears onscreen at least as often as MeganFox, is scarcely mentioned in many reviews, which (whether approving or disapproving) wish only to talk about Fox and Creator/DiabloCody.
* BlackComedy
* BodyHorror: As a horror movie involving a girl shifting into a demon would require.
* BrainyBrunette and DumbBlonde: Inverted. The brunette Jennifer is an [[BrainlessBeauty airheaded]] AlphaBitch (though it's implied that she's just playing dumb), while the blonde Needy is a HollywoodNerd.
* BreakTheCutie: Poor, poor Needy.
* BreastAttack: [[spoiler:"My tit!" Justified, seeing as Needy has to stab through Jennifer's breast to get to her heart.]]
* BuffySpeak: Creator/DiabloCody wrote this movie... [[{{Juno}} and it shows]].
* CassandraTruth: [[spoiler:Chip initially doesn't believe Needy's seemingly outrageous claims about Jennifer, not that you can blame him. Also, Needy is the only one who knows that Low Shoulder aren't the heroes everyone else thinks they are; no-one else believes her when she states otherwise, presumably because that's part of Low Shoulder's DealWithTheDevil.]]
* CatholicSchoolGirlsRule: See the poster.
* TheCheerleader: Vapid, skanky, and bullying... and that's before she gets possessed.
* ChekhovsGun:
** [[spoiler:The BFF necklace that Jennifer wears.]]
** The whirlpool beneath the falls. In Act I, Needy says that no one knows where it empties out at. In Act III, she finds out, finding Chekhov's Gun number 3:
** [[spoiler:The knife that Jennifer was sacrificed with.]]
* ContagiousPowers: [[spoiler:Being bitten by a demon and surviving gives you some of its power.]]
* CursedWithAwesome: Jennifer believes that her possession is essentially this (in a deleted scene, she is openly amused when Needy speculates about a possible cure for Jennifer's curse). [[spoiler:Needy herself becomes CursedWithAwesome at the end of the movie.]]
* DawsonCasting: 23-year-olds Megan Fox and Amanda Seyfried, and 22-year-old Johnny Simmons.
* DeathBySex: Played so straight it's likely a parody of this trope -- Jennifer uses the promise of sex to lure boys into places where she can eat them.
* DemonicPossession
* DepravedBisexual
-->'''Needy:''' I thought you only killed boys?
-->'''Jennifer:''' I go both ways.
* DidYouJustHaveSex
--> '''Jennifer:''' It smells like Thai food in here. Have you guys been fucking?
* DownerEnding: Some of the main cast are killed [[spoiler:(Jennifer and Chip)]], and Needy gets put in an insane asylum. [[BittersweetEnding On the plus side]], KarmaHoudini was averted since [[spoiler:Needy gained some of Jennifer's powers (super strength and levitation, at the least) and proceeded to escape and murder all of Low Shoulder.]]
* DramaticNecklaceRemoval
* DyingMomentOfAwesome: [[spoiler:Chip's [[ImpaledWithExtremePrejudice impalement]] of Jennifer.]]
* EnemyToAllLivingThings: When Jennifer is about to attack, animals all around her start fidgeting and screeching.
* EvilTastesGood: Jennifer describes the post-feeding "buzz" like this:
-->'''Jennifer:''' "You know when you kiss a boy for the first time and it feels like your entire body is on vibrate."
-->'''Needy:''' "Yeah."
-->'''Jennifer:''' "It's that good."
* FakeBand
* FanDisservice: Yes, it is Megan Fox, but it is somewhat difficult to find Jennifer sexy when she's covered in blood, has a mouthful of sharp piranha teeth, and is acting creepy as hell.
* {{Fanservice}}: The entire marketing campaign was built on [[MsFanservice Megan Fox's]] hotness.
* FilleFatale: Take a big guess at who.
* FingerSuckHealing: In a flashback, Needy did this for Jennifer when they were children. It is implied that this is why Needy is able to sense when Jennifer is about to kill someone.
* GigglingVillain: Jennifer indulges in some very creepy giggling shortly after her possession.
* GirlOnGirlIsHot: Is there any other reason why this film has a minute-long scene of Megan Fox and Amanda Seyfried making out?
* GlasgowGrin: Jennifer's face when she feeds has shades of this. When she opens her mouth to eat Jonas, her cheeks visibly split open.
* AGodAmI: After realizing her newfound healing ability, Jennifer burns her tongue with a lighter then loudly declares "I am a god."
* GodivaHair: Jennifer, before she eats Jonas.
* GoneHorriblyRight: Low Shoulder's "virgin" sacrifice. It got them fame and fortune (and drugs and hos) but it ''also'' brought back a man eating demon.
* {{Gorn}}: Jonas' corpse is briefly shown, entrails hanging out for all to see.
* GoryDiscretionShot: For most of the deaths.
* {{Goth}}: Colin.
* GreatBigLibraryOfEverything: Parodied when Needy discovers the truth about Jennifer's demonic possession from books found in the school library.
--> '''Chip''': We have an ''[[LampshadeHanging occult section]]'' in the library?
--> '''Needy''': Yeah. It's really small.
* HealingFactor: Jennifer gains healing powers upon her possession.
* HeartInTheWrongPlace: Jennifer places Jonas's hand above her left breast and asks him to feel her heart.
* HollywoodHypeMachine: From the marketing, to even the movie poster at the top of the page, this movie was pretty much an attempt to cash in on Megan Fox's status as an "It Girl." It backfired.
* HollywoodSatanism: Low Shoulder.
* HornyDevils: Jennifer - a type of succubus, to be exact.
* HorrorHunger: For everyone else involved, Jennifer seems to have no qualms about her new diet whatsoever.
* HowWeGotHere: The film starts with Needy in a mental hospital, and most of the film consists of her showing us how she got to that point.
* IDontLikeTheSoundOfThatPlace: Devil's Kettle.
* IHaveBoobsYouMustObey: Jennifer uses this to get drinks, despite being underage. She explicitly calls Needy's tits "smart bombs" for their destructive power.
* ImAHumanitarian: How Jennifer kills people.
* ImpaledWithExtremePrejudice: [[spoiler:Chip impales Jennifer with a large pole just before he dies. It doesn't kill her, but, hey, at least he tried.]]
* IndecisiveParody: One common criticism of the movie is the fact that it flops back and forth between being intentionally silly and seeming to take itself seriously.
* IntentionallyAwkwardTitle: Just try saying "Jennifer's Body" in a casual conversation without adding the words "the movie" before it. See what happens.
* JabbaTableManners: Jennifer, when she tries to eat the chicken from Needy's fridge.
* {{Jerkass}}: Jennifer starts out as one, but she becomes a lot crueler after her possession. Also Nikolai.
* JumpScare: Used a few times, most notably when Jennifer is standing ''right'' behind Needy shortly after her murder and possession, and then later in the same scene when she suddenly lets out a demonic roar. Also used when a bird frightens Colin when he is trying to find Jennifer in the partially-constructed house.
* KickTheDog: Jennifer loves doing this, particularly after her possession.
* MamaBear: Needy's mother invokes this.
--> I dreamed some bad people were trying to nail you to a tree with hammers and big stakes and shit. Just like [[Literature/TheBible J.C.]] But I didn't let 'em get to you, 'cause I'm a hard-assed, Ford-tough mama bear.
* ManipulativeBitch: Jennifer is an example of the type that ''doesn't'' have some big, complicated plan. Even when she starts killing people, her transparent playing on Needy's insecurities is closer to simple AlphaBitch bullying than towards any actual goal.
* ManlyTears: Jonas, after his best friend dies in the fire.
* MeaningfulName: The title.
** You'd never guess what Needy's defining trait is.
** The town too. Of course a demonic sacrifice would happen in a town called "Devil's ̶L̶a̶k̶e̶ Kettle".
* MoodWhiplash: Intentionally invoked in the scene that jumps between Jennifer seducing, then devouring some poor schmuck and [[spoiler:Needy and Chip's {{WAFF}}y sex]].
* MoreTeethThanTheOsmondFamily: Jennifer has lots of sharp little piranha-style teeth when feeding on people.
* NerdGlasses: Needy wears them.
* NeverTrustATrailer: The trailer contained some great one-liners cut out of the actual movie.
* NiceGuy: Chip and Colin.
* NightmareFace: Jennifer, when feeding.
* NinjaPirateRobotZombie: Chip invokes this when he says this about Jonas' mother: "She's staring out the window like a zombie mannequin robot statue."
* NothingIsScarier: Used to great effect shortly before Needy discovers Jennifer in her house.
* ObviouslyEvil: Nikolai, Low Shoulder's lead singer, is this in Needy's eyes.
--> I watched her get into that van and I knew something awful was going to happen. He was skinny and twisted and evil like this petrified tree I saw when I was a kid.
* OffscreenTeleportation: With a bit of creepy echoing whispers too.
* PopularIsDumb: Jennifer, who is clearly far ditzier than the less popular Needy.
* PowerFloats: Provides the page quote, too!
* ThePowerOfFriendship: Jennifer [[spoiler:loses her ability to levitate]] when Needy [[spoiler:rips off her BFF necklace]].
* PragmaticVillainy: At first, Jennifer only feeds when she absolutely ''has'' to, going at least a month inbetween killing [[spoiler:Jonas]] and [[spoiler:Colin]]. However, she [[JumpingOffTheSlipperySlope eventually]] starts killing simply for the hell of it...
* PreMortemOneLiner: Kind of, since it's not said to the victim (but precedes the credits in which the act is shown).
-->'''Passing Motorist''': So, why are you headed east?\\
'''[[spoiler:Needy]]''': I'm following this rock band.\\
'''Driver''': Must be one hell of a group.\\
'''[[spoiler:Needy]]''': Tonight's gonna be their last show.
* PsychicLink: It is strongly implied that Jennifer and Needy have one, following an incident when they were children in which Needy sucked the blood from a puncture on Jennifer's hand.
* RealityIsUnrealistic: The Devil's Kettle is a real waterfall. Half the river really does disappear into the ground. Scientists have ''no idea'' where it comes back out. (The town in the movie doesn't exist.)
* RoaringRampageOfRevenge: [[spoiler:After discovering that she has gained some of the demon's powers, Needy uses them to escape the mental institution, so she can track down and murder all of Low Shoulder.]]
* RockMeAsmodeus: Low Shoulder, the indie band that tries to sacrifice Jennifer in order to get a record deal.
* RomanticTwoGirlFriendship: Jennifer and Needy, although the trope is [[{{Deconstruction}} deconstructed]].
--> '''Needy:''' Sandbox love never dies.
* RuleOfPool: Just before Jennifer [[spoiler:eats Chip, Needy's boyfriend, she tosses him into a pool while he is wearing ''formal wear''. She then proceeds to jump in after him. Followed soon by Needy.]]
* RunningGag: One character constantly refers to Devil's Kettle as "[[AccidentalMisnaming Devil's Lake]]".
* SceneryPorn: The scene where Jennifer is swimming naked in a lake. The first shot of the scene is actually a wide-angle overhead shot with Jennifer's body only a tiny speck -- she's actually quite easy to miss, so for that shot at least the lake is the emphasis.
* SelfMutilationDemonstration: Jennifer burns her own tongue with a cigarette lighter, and slashes herself in front of Needy when she decides to share her 'secret' with her.
* SexDrugsAndRockAndRoll: Low Shoulder is living this lifestyle when we see them on tour at the end of the movie.
* SexSells: Just watch the film's ad campaign. Heck, the film's title is named after it.
* ShesGotLegs: Most of the movie posters.
* SirNotAppearingInThisTrailer: Amanda Seyfried ''does'' appear in the trailers, but apart from her name on top, she is absent from all the posters, which focus exclusively on Megan Fox.
* SlasherSmile: Jennifer displays one at various times. [[spoiler:Most notably after she first becomes possessed and when she appears in Needy's vision sitting on top of the chair watching her and Chip have sex.]]
* SlidingScaleOfComedyAndHorror: Slides all around this. Scenes go from funny to shocking to funny, then back to shocking. Usually with quite a bit of sexy in the middle.
* SoundtrackDissonance: Tracks like Panic! at the Disco's "New Perspective" and Florence and the Machine's "A Kiss with a Fist" seem a bit light for a horror movie.
** Not to mention an in-movie example when Low Shoulder sings Tommy Tutone's '867-5309/Jenny' as they murder her.
* StealthParody: A flimsy plot held together with [[{{Squick}} squicky]] {{Fanservice}} and generous helpings of [[LeaningOnTheFourthWall self-aware]] BuffySpeak.
* StealthPun: That quick one-liner when Jennifer calls Chip "lime green jello," when calling him jealous.
* StuffedIntoTheFridge: [[spoiler:Chip.]]
* SuperStrength: Jennifer gains this power following her possession, enabling her to seriously overpower Jonas, who is described as "the biggest guy in school". She also throws Colin around like a rag doll. [[spoiler:Needy also appears to gain this power after being bitten by Jennifer.]]
* TookALevelInBadass: [[spoiler:Needy.]]
* TotallyRadical
* TouchedByVorlons: [[spoiler:Needy gains some of Jennifer's demon powers after being bitten by her. She uses them to break out of the mental hospital and kill Low Shoulder.]]
* UnusualEuphemism: Jennifer seems to make a half her lines in this.
* VirginSacrifice: Low Shoulder tries to sacrifice Jennifer, thinking she's a virgin. Unfortunately, she's been [[ReallyGetsAround having sex since]] JuniorHigh. The ritual works as planned, but Jennifer gets possessed by a demon because she wasn't a virgin.
* VomitIndiscretionShot: Whenever [[spoiler:Jennifer vomits up that [[{{Squick}} demonic, spiny black sludge]].]]
* WithFriendsLikeThese: Jennifer walks all over Needy, although the latter doesn't want to see it until the end.
--> '''Needy:''' You know what? You were never really a good friend. Even when we were little, you used to steal my toys and pour lemonade on my bed.
--> '''Jennifer:''' And now, I'm [[spoiler:eating your boyfriend]]. See? At least I'm consistent.
