[[caption-width-right:320:It's Hayley Mills... and Hayley Mills!]]

A Creator/{{Disney}} live-action film that has been filmed twice. The original starred Hayley Mills and yielded three sequels which are hard to fit into one continuity (and are [[FirstInstallmentWins pretty much forgotten about]]). The remake starred a [[SheReallyCanAct (surprisingly brilliant)]] young Creator/LindsayLohan, Dennis Quaid, and the late, marvelous Natasha Richardson.

Twin sisters have been separated nearly at birth when their parents divorced. The year their father is considering remarrying, the sisters meet each other at summer camp. On meeting, they plot to get their parents back together, a plot that involves each pretending to be the other. HilarityEnsues.

The movie is based on a 1949 book, ''Das doppelte Lottchen'', which has also been filmed as ''Das doppelte Lottchen'' (a version that retains author Erich Kästner as narrator and uses actual twins), ''Twice Upon a Time'' and ''Hibari’s Lullaby'' (a Japanese telling).
!! ''The Parent Trap'' provides examples of:


[[folder: Both Movies]]
* AlwaysIdenticalTwins
* ButtMonkey: The fiancée in both versions.
* CoordinatedClothes: The twins wear matching outfits several times, sometimes to confuse the others about which twin is which. When the mother sees both her daughters for the first time since their separation, each is dressed in yellow and white. She tells them not to do this to her because she's already seeing double and asks who is who.
* {{Disneyfication}}: The original story was far more serious than the Disney movies--the father was distant, the mother was a wreck, and one twin falls ill.
* DontSplitUsUp
* DisproportionateRetribution: Hallie/Susan manages to very much overreact and initiate all the fights in both films.
* DivorceIsTemporary: The twins actively invoke this.
* EscalatingWar: The prank war between the twins.
* EvilDetectingDog: Susan isn't exactly evil, but Sharon's dog still figured out that she's an impostor much earlier than the father and the maid do. The same happens in the remake.
* FirstFatherWins
* GoodLuckGesture: Both versions of have a special gesture. They cross fingers (for luck) on both hands, with arms crossed (symbolizing the girls' Twin Switch). It was used much more in the original Haley Mills film.
* GuessWhoImMarrying
* HardWorkMontage: The twins use this to give each other information and mannerisms they'll need to remember when visiting the other parent.
* HilarityEnsues
* {{Identical Twin ID Tag}}s
* ImportantHaircut: Susan gives one to Sharon in the 1961 version and Hallie does the same to Annie in the 1998 version.
* {{Infodump}}: For everyone who is involved in the main plot.
* ItsASmallWorldAfterAll: Lampshaded.
* KarmaHoudini: The parents in both versions, who pay for willingly denying their children the chance to know about one another and having multiple family members and friends lie to them for years by being reunited as a couple and a family.
* NoSympathy: In the 1961 version, Susan and her bunkmates slip into Sharon's cabin and trash the place while Sharon and her bunkmates are asleep. Even though the damage is clearly the work of saboteurs, Sharon and her bunkmates are punished for having a messy cabin. The 1998 version makes more sense, with the cabin sabotage being the climax of the prank war that gets them both in trouble.
* NowYouTellMe: A lot of characters find things out the hard way.
* OffToBoardingSchool: What would have happened if the fiancee married the father.
* OneTruePairing: established in-universe, between Maggie [=McKendrick=] and Mitch Evers in the original, and Elizabeth James and Nick Parker in the remake-the daughters' reason for the trap.
* ParentTrapPlot: The TropeNamer.
* ParentWithNewParamour
* RemakeCameo: Joanna Barnes played Vicki Robinson (the fiancee) in the Hayley Mills version and Vicki Blake (the fiancee's mother) in the Lindsay Lohan version.
* RichBitch: The fiance in both versions. She serves the role as GoldDigger and ChildHater.
* RichInDollarsPoorInSense: The father in both versions.
* RuleOfPool: The father
* SeparatedAtBirth
* SettingUpdate: Both films move the setting to contemporary America.
* SiblingTeam: Once the girls discover they're sisters.
* SolomonDivorce: One of the best-known examples.
* TomboyAndGirlyGirl: Sharon is a girly girl, having been raised as a child of Boston high society; Susan is the tomboy. In the remake, there's the determined American, Hallie Parker, and the proper Brit, Annie James.
* TwinSwitch
* ZanyScheme

[[folder: The Original Version]]
* AnimatedCreditsOpening: With stop-motion.
* ArtisticLicenseMusic: Hayley Mills is not moving her fingers when playing guitar Beethoven's 5th Symphony. Then on "Let's Get Together" her strumming does not match the music (in addition to not moving her fingers).
* ColonelBogeyMarch: The other girls at the camp whistle this as the twins are escorted to the Isolation Cabin.
* DoomedNewClothes: Susan's new dress is ruined by Sharon as part of their prank war.
* DoubleStandardAbuseFemaleOnMale: Mom punches Dad [[EyeScream in the eye]]. What he says after being punched suggests she'd done stuff like that to him when they were married: "[[MenUseViolenceWomenUseCommunication Why do you have to get so physical? Can't even talk to you about anything, you're always trying to pelt me with something]]."
* ForegoneConclusion: The opening credits tell us the story in clay animation.
* FriendshipSong: "Let's Get Together" is this for the original film.
* NotEvenBotheringWithTheAccent: Hayley Mills, despite being an English girl playing two Americans from vastly different regions of the United States... pretty much just talks like Hayley Mills.
* PantyShot: From one of the pranks during the dance, when Sharon surreptitiously cuts the back off the skirt of Susan's party dress.
* TheRemake: The third adaptation of the same book, Erich Kästner's ''Das doppelte Lottchen'', and thus can itself legitimately be described as a ForeignRemake.
* VinylShatters

[[folder: The Lindsay Lohan Version]]

* AbbeyRoadCrossing: A second-long freeze frame as "Here Comes The Sun" plays in the background.
* AdaptationExpansion: The orginal movie ended with Mitch and Maggie falling back in love.
* BigEater: Hallie, but not Annie.
* BilingualBonus: Annie takes news of her father remarrying so harshly, she rants in French.
* BitchInSheepsClothing: The soon-to-be-[[WickedStepmother Step-Mom]] for Hallie.
* BookEnds: As part of Creator/AlanSilvestri's score, short, dramatic instrumentals of "Let's get together, yeah, yeah, yeah," accompany both the opening Walt Disney Pictures logo and the last few seconds of the end credits.
* BritishStuffiness: One of the twins is American and the other is British. Guess which is the proper one and which is the spunky one.
* CampStraight: If Martin doesn't qualify, I don't know who does. (see LittleBlackDress below)
* CountryMouse, CityMouse: Hallie is the Country Mouse coming from a vast vineyard in Northern California while Annie is the City Mouse coming from downtown London. Played with, though, in that Annie adjusts very well to camping in the forest.
* TheDitz: Both Marvas are quite bubble brained.
* EvilDetectingDog: In addition to the example listed in the top folder, Hallie's dog barks at Meredith in the hotel.
* ForeignLanguageTirade: As noted under BilingualBonus.
* FourthDateMarriage: Elizabeth and Nick, both times.
* GilliganCut:
--> '''Elizabeth:''' (to Hallie) You're not to worry, okay? \\
(cut) \\
I'm sorry! I can't handle this!
* GoneSwimmingClothesStolen: The StripPoker payoff at camp.
* GroundedForever: "We've been grounded till the end of the century." Which would have been much more threatening if the movie wasn't released in the Summer of 1998.
* HateAtFirstSight: Hallie and Annie hate each other from the moment they first see each other and see they look exactly alike.
* HideousHangoverCure: Elizabeth panicked during the flight and drank everything in sight, so this was necessary.
* ImAManICantHelpIt: Nick Parker. Annie lampshades this.
* IntoxicationEnsues: Elizabeth may not drink much, but she's a total lightweight.
* ItTastesLikeFeet: The bartender's HideousHangoverCure tastes and looks like tar.
* KindlyHousekeeper: Chessy, when she finds out, wants to coddle Annie and tries to cook everything in the kitchen for her
* LittleBlackDress: Martin, Elizabeth's butler and friend, suggests she take one on the trip to see Nick and switch the girls back. She's actually wearing it when they all go out to dinner.
* LogoJoke: The Walt Disney Pictures logo is accompanied by an orchestral version of an excerpt from "Let's Get Together" from the original movie.
* TheMagicPokerEquation
* {{Montage}}s: The movie makes liberal use of them:
** See HardWorkMontage in the "Both Movies" folder.
** Hallie's first day in London has at least two.
** At the end of the movie, [[spoiler:Elizabeth and Nick remarry, Martin proposes to Chessy, and Chessy says yes.]]
* MythologyGag: A few sentences from "Let's Get Together" song (made famous in the Hayley Mills version) are hummed/spoken by Lindsay Lohan at one point.
** Meredith's mother is not only named Vicki, but played by the same actress as her from the original movie, Joanna Barnes.
* NiceToTheWaiter:
** Chessy and Martin are like family to their respective employers. Averted with Meredith who treats Chessy like a talking dog who would be summoned with a bell.
** Chessy is even treated nicely by Elizabeth who was intoxicated at the time of their meeting again after years apart.
--->''' Chessy:''' ''[upon seeing Elizabeth after so many years]'' Hi, you probably don't remember me. I...\\
'''Elizabeth:''' ''[gives her a kiss on the cheek]'' Chessy!\\
'''Chessy:''' I knew I always liked her.
* OldManMarryingAChild: Used as an indirect accusation, delivered with SugaryMalice. When Nick tells his daughter that Meredith is about to become part of the family, she surely understands right away that he's talking about marriage. However, she pretends to innocently misunderstand him and get all ecstatic about how he's finally getting one more daughter by adopting her.
** A similar line happens in the original version ("I always wanted a sister!") but doesn't have the same insinuation as that version of the fiancee clearly looked like an adult.
* OohMeAccentsSlipping: Happens to both Hallie and Annie, more often to whoever has a British accent at the moment. Often it's the In-Character version of the trope. Lohan had to play four accents -- American, British, American pretending to be British, and British pretending to be American. The latter two had accents slipping. Lohan does a remarkable job in the scene at the hotel where she's basically playing four characters at once - Hallie, Annie, Hallie pretending to be Annie and Annie pretending to be Hallie. She switches up the accents just enough to do exactly what Hallie and Annie were after (confuse the heck out of Mom and Dad).
* ParentsKnowTheirChildren: Sort of--the father looks each twin in the eye and declares which one is Hallie; however, it's not made clear if he's right, since the twins keep playing up the charade and make him question his own judgment.
* PetHomosexual: Meredith's sassy gay assistant: "Ooh, Ice Woman!"
* TheRemake: Of the 1961 film (see above).
* TheReveal: In-universe, several times: first Hallie and Annie to each other (twice), then Annie to Chessy, then Hallie to her grandfather, then Hallie to her mother. And then Elizabeth dealing with the additional reveal of Nick's engagement to Meredith.
* RhetoricalQuestionBlunder: When Elizabeth is getting emotional about the thought of meeting Nick for the first time after so many years, she spouts off several of these to Martin.
* SandInMyEyes: Elizabeth is pleased that Nick still remembers the wine from their first wedding.
* SceneryPorn: Hallie arriving in London is of course an excuse for plenty of shots of the various landmarks. To a lesser degree, Annie arriving in California.
* ScreamDiscretionShot: When Hallie pierces Annie's ears, and when the girls drag Meredith's mattress into a lake.
* ServileSnarker: Nick's housekeeper, Chessy, and Elizabeth's butler, Martin. They also become attracted to each other [[LoveAtFirstSight at first sight]] and end up being the BetaCouple.
* SheCleansUpNicely: Nick has a reaction like this when Elizabeth gets dressed up for the dinner on the ship because he's only seen her half hungover though of course the audience has seen her looking flawless before.
* ShoutOut:
** Meredith is called [[Disney/OneHundredAndOneDalmatians Cruella DeVil]] several times.
** "The man went completely ashen, like I was the bloody [[Literature/AChristmasCarol Ghost of Christmas Past]]!"
* ShutUpKiss
* StrangeMindsThinkAlike: One of the first signs that something is funny about them is the fact that both of them like to eat Oreos topped with peanut butter, which everybody else seems to find disgusting (for some odd reason.)
* SwordFight: Hallie and Annie's first meeting is through an absurdly over-the-top "fencing match" at camp. The girls have fencing masks on as a way to save on special effects, to cover the faces of the stunt people, and for the big reveal that they both look alike when they take the masks off and face each other.
* TakeAThirdOption: When Chessy welcomes Annie!Hallie home, Chessy asks her if she'd like to eat lunch after upacking, before unpacking, or-to Annie's surprise-''while'' unpacking.
* TemptingFate: Annie waking up at the cabin disaster dodges several water balloons. "Gosh she didn't get me." and smiles with satisfaction. Then a HUGE water balloon falls on top of her soaking her.
* VillainousBreakdown: Meredith has one after being pranked by the twins and Nick dumps her.
* YouAreGrounded: After the girls scare Meredith off.
--> [[GoToYourRoom Up to your room]]. Now.
* YouthfulFreckles: Annie and Hallie have these, Lindsay Lohan's own.
