''Forgetting Sarah Marshall'' is a 2008 RomanticComedy (directed by Nicholas Stoller, co-produced by Creator/JuddApatow) written by and starring Creator/JasonSegel as Peter Bretter, a musician who has been dumped by the titular Ms. Marshall (Creator/KristenBell), his TV star girlfriend. After a string of one-night stands, Peter decided to go on vacation to Hawaii to forget, erm, well, [[TitleDrop you know]]. Unfortunately for Peter (but fortunately for us the viewers), Sarah is staying at the same resort with her new flame, BritishRockStar Aldous Snow (Creator/RussellBrand). Peter makes new friends, and starts to date Rachel (Creator/MilaKunis), a receptionist at the resort. Schadenfreude happens. HilarityEnsues.

Later spawned a SpinOff, ''Film/GetHimToTheGreek'', featuring Brand reprising his Aldous Snow character from this movie alongside Jonah Hill, who, rather confusingly, does ''not'' reprise his role in this movie.

!!Provides examples of:
* AffectionateParody: ''Crime Scene: Scene of the Crime'' is clearly a parody of ''Series/{{CSI}}'', using the same naming convention. Later on, a characters asks Jason Segal's character if he works on ''Crime Scene: Scene of the Crime'' (sounding enthusiastic) or ''Crime Scene: Phoenix'' (sounding mildly depressed), clearly a parody of the multiple spinoffs in the CSI franchise and the general consensus by viewers and critics that the original is the superior crime drama program, whereas the spinoffs (named after the cities they are set in) are considered kitschy and tacky.
* AllGirlsWantBadBoys: Aldous Snow does quite well with the ladies, despite being pretty bad boyfriend material, which is {{lampshade}}d by Peter.
* AlohaHawaii
* AntiLoveSong: Peter [[http://www.youtube.com/watch?v=pB_1t-Vn6Vs sings one]] [[SelfDeprecation to himself]].
* BetaCouple: Darald and Wyoma, Brian and Liz
* BettyAndVeronica: Sarah (Archie) between Peter (Betty) and Aldous (Veronica). Peter (Archie) between Rachel (Betty) and Sarah (Veronica).
* BigNo: Done with absolute hilarity.
* BloodFromTheMouth: When Peter finally completes his Dracula-puppet rock opera, the titular puppet dies at the end, complete with red silk blood from the mouth.
* BreakoutCharacter: Aldous Snow was so popular, that Stoller made the spin-off film ''{{Get Him to the Greek}}'' about him.
* BreakUpBonfire
* BreakUpToMakeUp: Not initially, but Peter does eventually go in this direction.
* BriefAccentImitation: "Oh! I'm Aldous Snow! Boo-shit boo-shit boo-shit boo-shit!"
** Also, Matthew, when giving Aldous his demo tape:
---> '''Matthew:''' "OH! I saw that guy! He was my waiter and I totally dismissed him like everybody else does... in his life. And I totally, she was wrong cuz he's a major, major, major influence on me now... and I feel terrible!"
---> '''Aldous:''' That stupid English voice, was that me?
---> '''Matthew:''' Unfortunately, yes.
** Also Paul Rudd's Chuck/Kunu:
---> '''Chuck:''' You sound like you're from London!!
* BritishRockstar: Aldous is an excellent example, but his complexity also makes it a subversion.
* ButtMonkey: Peter spends the first half of the movie as this. Many gags center on how miserable he is after getting dumped and seeing his ex-girlfriend so happy with a new man.
* CallingYourOrgasms: One of Peter's one-night stands. Later played with, as Peter calls ''Rachel'''s, screaming, "She's having an orgasm!", [[RightThroughTheWall to Sarah]] as part of an odd sex competition.
* CaptainErsatz: Billy Baldwin's "Scene of the Crime" character is pretty clearly a [[AffectionateParody parody of]] and/or [[{{Homage}} homage to]] one [[CSIMiami Horatio Caine]].
* TheCastShowoff: Jason Segel's songwriting and singing abilities. RussellBrand sings too.
* CringeComedy
* DepartmentOfRedundancyDepartment: Sarah stars on the TV show "''Crime Scene - Scene of the Crime''."
* DespairSpeech: Peter has a despair ''song''.
* FanDisservice: This movie has way, way too much male nudity - although it may be a FanService to female viewers.
** [[NakedPeopleAreFunny Or...]]
* HauntedTechnology: Sarah was in a movie where cell phones kill their owners; Peter and Aldous mock this over a dinner. This is also an ActorAllusion to a previous role of Kristen Bell's.
* HawaiianShirtedTourist: Peter, apparently in ignorance. When Rachel tells him to change his shirt before their date, he's taken off guard.
* HulaAndLuaus
* TheImmodestOrgasm: When the two couples try to outdo each other.
* IntercourseWithYou: Aldous's song "Inside Of You".
* JerkassHasAPoint: [[spoiler:When it's learned that Sarah cheated on Peter for an entire year before dumping him, it makes the audience feel like she's the biggest bitch in the world. But when Peter confronts her about it and she starts listing the reasons why she cheated, you kinda have to admit that she makes some good points.]]
* LaserGuidedKarma: [[spoiler:Sarah, who cheated on Peter, eventually finds out that Aldous has been cheating on her.]]
* TheLoinsSleepTonight: When Peter [[spoiler: tries to have sex with Sarah.]]
* LoveHurts: For everyone, except maybe Aldous.
** Maybe not:
---> '''Aldous:''' I would rather have my testicles spread out like a wafer and then have them covered in a layer of honey and then have wasps come and sting me and then have them covered in another layer of vinegar and then have it worn as a swimming cap by a Nazi. I'd rather have that than spend another second with her.
* LookingForLoveInAllTheWrongPlaces: After being dumped at the start of the film, Peter has a series of meaningless one night stands in an attempt to get over Sarah.
* MaleFrontalNudity: Peter, used for laughs.
** Doubles as a MeaningfulName, since Peter is a euphemism for "penis". Though it is far less commonly used than Dick.
** May count as BookEnds. The first scene has him naked trying to get a hug from his (ex) girlfriend, and the last scene has him naked getting a kiss from his (different) girlfriend
* AManIsAlwaysEager: Averted; Peter is unable to get aroused enough to have sex with Sarah because he can't forget about her recently breaking his heart.
* ManicPixieDreamGirl: Rachel.
* {{Metaphorgotten}}:
-->'''Chuck:''' I like red hair. I wonder if the carpet matches her pubes.
* TheModestOrgasm: One of the women Peter sleeps with.
-->'''Woman:''' [Dead monotone] Oh. Oh. Oh. Oh. I just came. Oh. Oh. Oh.
* ModestyBedsheet: Used several times due to both Kristen Bell and Mila Kunis refusing to do nude scenes.
* MundaneMadeAwesome: ''Crime Scene: Scene Of The Crime''
* MyGodWhatHaveIDone: [[spoiler:Sarah goes through one of these after her break-up with Aldous. She realizes that Peter is actually a pretty great guy and she made a huge mistake by cheating on him and then dumping him.]]
* NakedPeopleAreFunny: Full frontal nudity from Jason Segel. Twice.
* NiceGuy: Aldous, despite being a sex maniac who was sleeping with Sarah behind Peter's back (and with various other women behind Sarah's back...), is actually really friendly and cordial towards Peter, which only serves to piss him off more. Peter even admits that it's very hard to hate him.
* NoAntagonist: Pretty much everyone in the cast is guilty of some sort of major breach of trust against one another, but all show a good deal of humanity and redeeming qualities as well. The proceedings come off more as a tragedy than the "Sarah did bad thing, root for Peter" the beginning would have you expect.
* OneHeadTaller: Peter (6'4"), Sarah Marshall (5'1"), Rachel (5'3"). Lampshaded in the beginning by a photographer who calls Peter "Jolly Green Giant" when telling him to get out of the shot.
* PetTheDog: Aldous is by no means a bad guy, but he does do something helpful in the movie when he assists the young newlywed with his apprehensions about sex, resolving a running gag that had been making Peter rather uncomfortable in the process.
* PrecisionFStrike: "''Fuckerrr!''"
* ProtestSong: Aldous Snow and Infant Sorrow recorded a similarly satirical piece entitled ''We Gotta Do Something''.
* QuipToBlack: {{Lampshade}}d / [[AffectionateParody Parodied]]: "She's going to have a hard time reentering the pageant...without a face."
* RightThroughHisPants: Inverted, where there is more male nudity than female, and the full-frontal male nudity starts in the first 10 minutes of the movie.
* RightThroughTheWall: The two couples end up with rooms next to each other. Peter and Rachel are intentionally loud to annoy Sarah. Sarah retaliates by faking, much to Aldous's annoyance.
* RomanticFalseLead: Subverted. Aldous Snow is initially presented as the RomanticFalseLead (and Peter thinks he is), but as [[spoiler:Peter doesn't get back together with Sarah in the end (and stops trying about halfway through the movie),]] he's not.
* SexForSolace: Peter has a string of emotionless one night stands after he is dumped by Sarah, his pediatrician explains that he needs to get past Sarah and this is the perfect way to do so.
* SoundtrackDissonance: Invoked. After Sarah breaks up with him, Peter is shown at his keyboard putting a score to an episode of ''Crime Scene: Scene Of The Crime''. When it's announced that the VictimOfTheWeek's penis was caught in an air conditioner, Peter sets it to the theme song from ''{{Seinfeld}}''.
* ShootTheMoney: Averted. Shot on location in Hawaii and showed almost none of it. According to Russel Brand's later live comedy special, they shot a lot of outdoor sports scenes on beautiful beaches with him that were cut because he absolutely fails at surfing and horseback riding.
* ShoutOut: Peter sings a very flubbed version of TheMuppetShow theme song.
* {{Spinoff}}: ''GetHimToTheGreek'' which focuses on Aldous Snow.
* StalkerWithACrush: Matthew to Aldous. He's definitely a stalker and it's hinted that he's also attracted to him.
** Hinted? When Aldous sings "Inside of You", Matthew adjusts his pants and says "It just went from 6 to midnight." Yeah.
* StylisticSuck: Sarah's [[ShowWithinAShow TV show]] ''[[ShapedLikeItself Crime Scene: Scene of the Crime]]''.
* SupernaturalPhone: Peter and Aldous mock titular faux film star Marshall's having appeared in a film about a murderous cell phone, wondering why the phone could not be defeated by simply removing the battery.
* SurferDude: Peter gets lessons.
* TakeThat: To ''Film/ChakushinAri''/''Film/OneMissedCall''. See SupernaturalPhone above.
* TheUnfairSex: Averted; Sarah's cheating on Peter is portrayed negatively.
* VerbingNouny: The title.
* VampireMusicals: Peter has made a Dracula musical with puppets.
* WhenLifeGivesYouLemons:
-->'''Chuck:''' When life gives you lemons, just say "Fuck the lemons" and bail.
* WrittenByCastMember: Creator/JasonSegel
* YourCheatingHeart: Sarah is both a perpetrator and a victim at different points.
* YouShallNotPass: Parodied in the scene where Peter wore the same pair of sweat pants for a week.
