A 1997 RomanticComedy directed by P.J. Hogan, starring Creator/JuliaRoberts and Creator/CameronDiaz.

Julianne Potter (Roberts) is a restaurant critic from New York who, turning 28, realizes she's getting dangerously close to being a stale OldMaid. In college she and her best friend, Michael O' Neal (Dermot Mulroney), had made a pact that the two of them [[FallbackMarriagePact would marry each other if neither of them were married by the time they reached 28]]. He calls close to her birthday... only to tell her that he's found a pretty, wealthy, cheerful young bride in the person of Kimberly Wallace (Diaz), who wants her to be her maid of honor. She heads to Chicago, to not only become said maid, but also try and [[RelationshipSabotage sabotage the wedding]] and get Michael for herself. HilarityEnsues.

The film opened, embarrassingly, behind ''Film/BatmanAndRobin'' in theaters, but went on to make nearly $300 million at the box office. It also received mostly positive reviews.

!!This film provides examples of:

* AlmostKiss: Lampshaded; "sometimes the moment just... passes you by."
* BareYourMidriff: Julianne does this a few hours before the wedding.
* TheBeard: Julianne asks George, her GayBestFriend, to pretend to be her boyfriend to make Michael jealous.
* BestWoman: According to Michael's father, Julianne was close to becoming one.
* BittersweetEnding: Julianne gives up on Michael and he goes on to marry Kimberly, making amends to both for her actions. While she's happy for the two, is visibly saddened that she [[DidNotGetTheGirl did not get the guy she's been fawning over since college]]. However George, probably sensing this, quickly books a flight back to Chicago from London and arrives at the reception to come cheer her up.
* ChickFlick: Romance, weddings, karaoke, etc.
* ChildhoodMarriagePromise: College, but still all the trope entails.
* ClingyJealousGirl: Julianne can't stand the thought of any girl with Michael that is not herself.
* CoolBigSis: Kim really wants Julianne to become this to her. Little did she know Jullianne exploited the position to give her bad advice.
* CrowdSong: "I Say A Little Prayer". It's the gay guy that starts it off to try to make the ruse of being Julianne's boyfriend convincing. The rest just join in and even the restaurant staff help out by providing the music.
* DerailingLoveInterests:
** Invoked, as Julianne plots RelationshipSabotage.
** Averted regarding Julianne, who shows clear signs of being a psycho bitch through the film (which are at first concealed by our expectations of the genre), and the script is ''not'' shy about how bitchy she is... [[TropesArenotBad But that]] [[JustifiedTrope is the point.]] Julianne [[WhatTheHellHero gets chewed out for her actions]]. The GayBestFriend constantly tells her that her idea is stupid, the NiceGuy is upset when Hell breaks loose, and [[spoiler: when Julianne has to confront Kim on the shit she did to her, ''all'' the women in the scene side with Kim and call Julianne "bitch", "slut" and "couple breaker" in the most hilariously awesome way ever possible.]]
* DidNotGetTheGuy: Julianne, our VillainProtagonist, does not marry her best friend.
* FagHag: Julianne's best friend (apparently her OnlyFriend aside from Michael) is the homosexual George.
* FallbackMarriagePact: The setup for the whole plot; Julianne is still single when the pact expires but Michael is not.
* FieryRedhead: Julianne's temper is shorter than HairOfGoldHeartOfGold Kimberly and she is more prone to shouting.
* FocusGroupEnding: ExecutiveMeddling wanted Julianne to get together with a random guy at the wedding reception, but audiences didn't like it, so the originally-written ending where her gay friend George comforts her was made instead.
* FourthDateMarriage: Part of the reason Julianne is so mad that he'd marry Kimberly, since he barely knew her while she and Michael have been friends for years already.
* GenreDeconstruction: A romantic comedy where the protagonist comes to realise that ''she'' is the RomanticFalseLead. Several {{Zany Scheme}}s are scuppered when RealityEnsues and/or the couple make up because they're genuinely in love.
* GreenEyedEpiphany: Julianne thought of Michael as her "best friend" until she heard he was getting married.
* HeelRealization: At one point, Julianne even ''says'' "I'm the bad guy."
* HeliumSpeech: The boys sing a ballad with helium sucked from the wedding's balloons.
* HeroicBSOD: [[spoiler: Happens to Kim, when Julianne kisses Michael. The poor girl runs away in tears and disappears.]]
* HollywoodToneDeaf: Kimberly is an aversion. Cameron Diaz's karaoke sounds realistically off.
* IgnoredEpiphany: There are several moments during the film where Julianne appears to realize how awful the things she is doing are, but they don't really stick until the end.
* IrrevocableMessage: Julianne sends an e-mail from Michael's account in an attempt to cause trouble between him and Kim. She realizes how wrong it was once it's too late.
* ItsAllAboutMe: Julianne is all about this trope. She wants Michael for herself, and is willing to do anything to get him. Who cares that he's in love with (and about to marry) someone else?
%%* IvyLeagueForEveryone
%%* ManicPixieDreamGirl: Kimberly being a good example.
* MustMakeAmends: [[spoiler: Julianne [[ForcefulKiss forcibly kisses]] Michael. Kimberly catches them, [[MistakenForCheating believes he's cheating on her]], and runs away in the middle of an HeroicBSOD. Julianne realizes that Michael ''really'' cares for Kim, so she's the one who has to convince Kim to come back for Michael's sake. By the time the two met again, Kim had decided to fight back for Michael. Most of what Julianne did at that point was to assure her that she just kissed Michael suddenly when he wasn't expecting it and that Michael never kissed her back, and to let Kim know that she was giving up.]]
* NoSympathy: Subverted in the karaoke scene. The crowd's initial response to Kimberly's HollywoodToneDeaf singing is a humiliating stunned silence, but then they start to cheer and clap and she starts to laugh along with them.
* OldMaid: Julianne didn't care about her age and not being married yet... until Michael told her "I'm getting married to Kim, whooo!"
* PoorCommunicationKills: Subverted. Julianne engineers a huge row between the fiancés, but just as Michael is about to storm off, Kimberly bursts into tears and apologises.
* PrecisionFStrike: When Jules is trying to convince Michael and Kimberly that her gay male friend is really her boyfriend. "He's coming over to ... um ... fuck me."
* ProtagonistJourneyToVillain: Jules's schemes get more diabolical and mean-spirited as the film goes on to the point where she is basically a VillainProtagonist. [[spoiler: She gets better by the end.]]
* RelationshipSabotage: The whole plot is about Julianne's attempt at breaking up the engaged couple.
* RomanticFalseLead: The subversion of this ends up being the crux of the story. One expects the two leads to hook up as VictoriousChildhoodFriend and the third to be a DisposableFiance, but that is not the case here.
* SpringtimeForHitler: Julianne arranges for Kimberly to humiliate herself at a karaoke bar, but ([[RealityEnsues what with it being a karaoke bar]]) everyone cheers and applauds her awful singing and Michael looks impressed that she has guts to go along with it.
* VillainProtagonist: The major gimmick of the film is having the RomanticFalseLead as the main character.
* WhatTheHellHero:
** As said before, the script does not try to pass Julianne's actions as acceptable, and that goes double for the characters after she [[spoiler: kisses Michael.]] Which leads to a rather funny scene in a ladies bathroom:
-->'''Kim:''' You [[spoiler: kissed him [Michael]!]]
-->'''Spectators:''' *gasp*
-->'''Kim:''' In my parent's house!
-->'''Spectators:''' *''gasp''*
-->'''Kim:''' ON MY ''WEDDING DAY!''
-->'''Spectators:''' *''GASP''* Bitch....Tramp...
** George tells Julianne right off the bat he doesn't approve of what she's doing when she ropes him into her scheme. It's implied he deliberately overdoes the acting while posing as her boyfriend in the hopes Julianne will come to her senses.
%%* WhyCantIHateYou: Julianne toward Kim.
