''Monster'' (2003) is a biographical crime drama about serial killer Aileen Wuornos, a former prostitute who was executed in 2002 for killing seven men in the late 1980s and early 1990s. Wuornos was played by Creator/CharlizeTheron, and her lover, Selby Wall, was played by Creator/ChristinaRicci (Wuornos' lover's name was actually Tyria Moore, but her character's name, age, and appearance in the film were changed for legal reasons). The film was written and directed by Creator/PattyJenkins.

Theron earned the UsefulNotes/AcademyAward, Golden Globe Award, and Screen Actors Guild Award for performance as Wuronos.

This movie has no connection with the anime and manga ''Manga/{{Monster}}'' or the sci-fi film ''Film/{{Monsters|2010}}''.

!! This movie provides examples of:

* AdaptationalAttractiveness: Tyria Moore, Wuornos' real-life girlfriend, looked like [[http://26.media.tumblr.com/tumblr_lr1c870CtE1qkku9po1_250.jpg this]]. [[{{Bifauxnen}} Selby Wall]], on the other hand, is played by Creator/ChristinaRicci.
* AdaptationDistillation: Aileen and Tyria lived together for years before Aileen committed her first murder. In the film, Aileen and Tyria (here renamed "Selby") first meet only days before it.
* AssholeVictim: Let's face it, Aileen's first victim [[PayEvilUntoEvil had it coming]]. The rest... didn't.
* BeautyInversion:
** Creator/CharlizeTheron gained between 20 and 30 pounds and shaved her eyebrows to play Wuornos. With all the press for a young beautiful actress with [[DyeingForYourArt that kind of dedication]], she got the Best Actress Oscar in a walk.
** Creator/ChristinaRicci also gained 20 pounds for the role and both actresses dressed in very un-glamourous clothing.
* BeCarefulWhatYouWishFor: In a very meta sense. In the opening narration, Aileen says she always wanted to be in the movies.
* BrokenBird: Very, very broken. To say nothing of her real-life childhood (the film begins in 1989), she is raped and commits her first murder in self-defense, tries but fails to get out of prostitution when no one will hire her, suffers from schizophrenia, and things only go further downhill when she starts to kill again.
* ClusterFBomb: Several, but Aileen's failed job interview at the hands of a ''very'' [[{{Jerkass}} smug lawyer]] deserves mention.
--> '''Lawyer:''' I see you're from Daytona Beach, all of that looks great, it must be wonderful. But can I tell you something? When the beach party is over, you don't get to say, "You know what? Now I think I'd like to have what everybody else has worked their entire life for." It doesn't work that way.
--> '''Aileen:''' ''(beat)'' Fuck you, man. Yeah, ''fuck you!'' '''YOU DON'T FUCKIN' KNOW ME!'''
--> '''Lawyer:''' Okay, great. That's great. [[SarcasmMode See, now I'm so sorry I didn't hire you before]]. Leslie, could you please escort Miss... I don't even know her name because of course she doesn't have a resume... out.
--> '''Aileen:''' I don't need a fuckin' escort, you piece of shit! What, you think I'm a fuckin' retard? Take your fuckin' job and fuckin' shove it!
--> ''(Leslie hesitantly tries to escort her out of the building)''
--> '''Aileen:''' ''Fuck you'', Leslie!
* DisposableSexWorker: Subverted. The first victim, played by Lee Tergesen, tries to turn Aileen into this but she kills him.
* DisproportionateRetribution: Aileen goes from murdering an abusive would-be pimp who sexually assaults her to murdering guys just for indulging in prostitution to murdering men just because she's pissed and they're there.
* DoomedByCanon: Well, doomed by real life. After killing her first victim, Aileen makes a desperate attempt to quit prostitution and find some other means of earning a living. It... doesn't go well.
* DrivenToSuicide: Aileen was fully intending to kill herself prior to meeting Selby.
* FanDisservice: Aileen and Selby's sex scene, although this is probably intentional (yet it is also played in a rather sweet manner). Also, the scene with Aileen glancing at her naked, bloodstained body in the bathroom mirror.
* HowlOfSorrow: When one of her victims starts crying and begging for his life, Aileen snaps and shoots him dead while letting out one of these (although it's more like a Howl Of Rage).
* IfItsYouItsOkay: Aileen doesn't consider herself gay, but enters into a loving relationship with Selby.
* IHaveAFamily: One of Aileen's victims tries this very shortly before she pulls the trigger on him.
* {{Jerkass}}:
** Good luck trying to find a moment in the movie where Aileen herself isn't a bitch. She arguably crosses into JerkassWoobie territory on a few occasions, though.
** The lawyer Aileen launches a ClusterFBomb against, and the cop who picks her up while she's jobhunting.
* LargeHam: Most of the main characters play ''everything'' like this, even the most innocuous scene. This contributes to the absurdly-funny atmosphere despite the tragedy of the events.
* LoveMakesYouEvil: Part of Aileen's motivation for the murders is so she can rob her victims afterwards to support herself and Selby.
* MisanthropeSupreme: Aileen. Selby: "You can't kill people." Aileen: "SAYS WHO?"
* [[SirSwearsALot Miss Swears-a-Lot]]: Aileen loves her swearing. This slips after the first half hour in the film into HistoricalVillainDowngrade: (dangerously-psychotic in RealLife) Aileen after a few scenes of hysterical antics appears rather [[YouWereTryingTooHard absurdly funny]].
* OhCrap: Aileen when she finds one victim's badge.
* OnlyKnownByTheirNickname: Aileen is mostly referred to as "Lee" throughout the film.
* PayEvilUntoEvil: Aileen kills her first victim after he rapes and brutalises her. With all her later victims, however, she ''believes'' that she is [[PayEvilUntoEvil paying evil unto evil]], when, in all actuality, they didn't deserve it.
* PetTheDog: Aileen spares one of her intended victims out of pity, after it turns out he's never hired a prostitute before and is extremely nervous. Of course, she immediately follows this act of mercy by [[KickTheDog murdering an innocent man]] who just wanted to help her get home.
* PsychoLesbian / DepravedBisexual
* SerialKiller: Aileen Wuornos is perhaps the most infamous female serial killer in United States history.
* ShellShockedVeteran: Thomas hints at being this, during his conversation with Aileen. "What you're feeling right now is guilt, over something you had absolutely no control over. Do you know how many of us came back from the war, and almost killed ourselves because we felt exactly the same way?"
* ShoutOut: "Gassenhauer" is played, an obvious homage to ''Film/{{Badlands}}''.
* ShownTheirWork: The way the movie portrays what happened to Aileen was probably very close to the truth. She killed her first victim out of self defense, and her [[http://www.youtube.com/watch?v=yFBcjII3QAE rising schizophrenia]] likely helped her jump to some unusual conclusions that led her to continue. The director also personally met with Wuornos to get the film as accurate as possible.
* SocietyIsToBlame: Aileen had been forced into prostitution and ended up being raped, leading her to kill in self-defense. Which [[JumpingOffTheSlipperySlope led to her committing more murders]]. Indeed, her real life final words were to this very effect.
* ThereIsNoKillLikeOverkill: Arguably {{justified|Trope}}. After being raped by the man who turns out to be her first victim, Aileen escapes, grabs his gun, blasts him several times, continues firing into his corpse and does not stop until she's completely emptied the clip. Shortly after, she starts beating his corpse with the gun whilst punctuating each beat with rage-filled insults. Of course Aileen follows up this act of self-defense with a string of cold-blooded murders, all while still using the justification of self-defense.
* VillainProtagonist
* WoobieDestroyerOfWorlds: Aileen may have been depraved, but damn if she hadn't been given an awful deck of cards.
