''Swimming Pool'' is a 2003 thriller film directed by François Ozon, starring Charlotte Rampling and Ludivine Sagnier.

It is about an English writer named Sarah Morton (Rampling) who receives an offer from her publisher to take some time off and spend it at his estate in France. Sarah accepts, and subsequently begins working on a new novel, but shortly afterward, her publisher's adult daughter Julie (Sagnier) arrives and decides to spend some time at the house as well.

!!This film provides examples of:
* AmbiguousEnding: [[spoiler:Which Julie is the real one and which is the imaginary one? If the young one is real, was she with Sarah at the French house doing all those things? Or did Sarah just invent the crazy stuff? Alternatively, was Julie even there at all? Is Franck actually dead? Did he even ever come to the house?]] Lots of questions, to be sure... these are just a few.
* BettyAndVeronica: Sarah is Betty (wise and restrained), while Julie is Veronica (youthful and sexual) to Franck.
* BrainyBrunette: Sarah.
* BrokenBird: What Julie actually is, though she doesn't like to show it.
* DeathBySex: The punishment [[spoiler:Franck]] receives for ''not'' having sex with Julie.
* DisappearedDad: Julie's father is this to her. [[spoiler:The ending suggests otherwise, though]].
* DistractedByTheSexy: Sarah uses this trope on Marcel so he stops paying attention to [[spoiler:the fresh ground where she and Julie buried Franck.]]
* {{Foil}}: Julie is one to Sarah in most ways; she is young, energetic, free-spirited and blonde, while Sarah is middle-aged, calm, reserved, and brunette. They both like to drink and smoke, though.
* FullFrontalAssault: Julie is completely naked when she [[spoiler:murders Franck.]] Except [[spoiler:Sarah may have actually done that.]] [[{{MindScrew}} Or maybe it didn't happen at all]].
* GirlsLoveStuffedAnimals: Julie has a big teddy bear in her bedroom.
* GrandmaWhatMassiveHotnessYouHave: Charlotte Rampling was 57 years old when the film was made, not quite a grandma but definitely older than most of the other cast members she interacts with. However, she is lusted after by more than one male character in the film.
* ImaginaryFriend: [[spoiler:The adult-aged Julie ends up being one of these to Sarah]]. Probably.
* IntergenerationalFriendship: Sarah and Julie form one eventually.
* LightFeminineDarkFeminine: Subverted. Julie is usually lighter than Sarah but she's much more sexual and carnal.
* LookingForLoveInAllTheWrongPlaces: Julie fits this trope to a T.
* LoveTriangle: One appears to be starting among Julie, Sarah, and Franck.
* MaleFrontalNudity: It's not a lenghty scene, but you'll certainly notice when it happens.
* ManicPixieDreamGirl: In a way, Julie is this for Sarah.
* MissingMom: Julie's mother. Julie tells Sarah that her mother lives in Nice, [[spoiler:but she's actually dead.]]
* MostWritersAreWriters: Sarah, the protagonist, is an author of mystery books.
* MsFanservice: Julie.
* NippleAndDimed: Julie seems to really enjoy being topless.
* NotSoDifferent: Sarah invokes this trope after she accepts a puff from a joint from Julie, and alludes to her days in Swinging London.
* ReadyForLovemaking: Sarah, to Marcel. First she invites him in through the use of {{sexy coat flashing}}, and once he enters her room, she's lying nude on her bed.
* SkinnyDipping: Julie sometimes prefers this, and on one occasion she persuades Franck to join her.
* StuffyBrit: Julie views Sarah as one during the first part of the film, and even describes her this way to a friend during a phone call.
* TwistEnding: The film is well-known for having one, and it's the subject of much debate.
* TwoPersonPoolParty: Julie clearly wants to have one with Franck, and they start taking some steps in that direction, but he decides to stop it.
* [[{{UglyGuyHotWife}} Ugly Guy, Hot Girl]]: The two men that Julie brings home and sleeps with are ''much'' less attractive than she is. This may be part of Julie's character, because she's a {{hard drinking party girl}} and thus might not have such high standards. Or it could be because {{most writers are male}}.
* WalkingSwimsuitScene: Sarah has one. Julie has several.
* WritersBlock: Sarah is suffering from this in regard to her detective series, which is what prompts her publisher to suggest the vacation at his house in France.
