!!Tropes used in the film:
* AtTheOperaTonight: Both Ariane and Frank attend the opera with different people. Ariane can only focus on Frank, and Frank can only focus on [[MenAreUncultured how bored he is]].
* BilingualBonus: The Japanese newspaper article on Frank Flannagan does not mention him, but rather reads "The great newspaper king Kane dies". This is the same article used in the montage in ''Film/CitizenKane'', with the name and picture of Frank Flannagan added in.
* BlatantLies: Ariane's romantic history.
* TheCasanova: Frank Flannagan.
* ChekhovsGunman: The cuckolded husband who features in the opening scenes and winds up causing Frank and Ariane to meet then disappears from the movie, until towards the end, when he pops pu again and recommends Ariane's father Claude as a detective for Frank.
* DiegeticSwitch: The waltz "Fascination" is used as a motif for Frank and Ariane, both playing over the soundtrack and sung/played InUniverse. In one scene the music seems to be playing over the soundtrack while Frank's in the sauna, only for the camera to turn and reveal that Frank's musicians have actually followed him into the shower, and are playing, while soaking wet.
* DoggedNiceGuy: Michel makes his feelings for Ariane no secret, but she just brushes him off.
* DressHitsFloor: In this case it's Fur Coat Hits Floor. Frank tells Ariane to take off her coat as the two make out, and we see the coat fall like a dress.
* FakeOutMakeOut: Flannagan and Ariane pretend to make out when a jealous husband breaks into Flannagan's hotel room.
* FemmeFatale: Ariane pretends to be one to get Frank's attention.
* GayParee: Everyone is in love in Paris; children, animals, even the undertaker at a funeral!
* ImNotPretty: Ariane's opinion on her appearance: "I'm too thin, and my ears stick out, and my teeth are crooked and my neck is much too long."
* LadykillerInLove: Frank with Ariane.
* MayDecemberRomance: Ariane is stated to be 18, and though Frank's age isn't given, no attempt is given to make his character seem young. Cooper was 55 at the time of filming and Hepburn was 28 in RealLife. The large age gap was one reason for the poor critical reception the movie received.
* MissingMom: Ariane's mother.
* OverprotectiveDad: Mr. Chavasse doesn't let Ariane read his case files and has a full dossier on Michel, though he is quite level headed when comes to confronting Flannagan.
* PoliceAreUseless: They can't investigate until after a crime has been committed.
* PrettyInMink: Ariane borrows an ermine coat as part of her first seduction of Frank. The coat was a gift a rich man planned to give [[TheMistress his mistress]], then his wife after the reconciled, and then his mistress again when he saw his wife wearing an apparent trinket from an affair.
** One of Frank's dates wears a white ermine wrap when they attend the opera.
* ReallyGetsAround: Frank Flannagan.
* RunningGag: With the lady and her dog in the neighboring hotel room.
* SherlockScan: While Mr. Cravasse takes a while to catch onto his daughter having an affair with Flanagan, he shows eerie observational skills in some situations. For example, he knows that Ariana hasn't been with Michel because she has a callus from carrying her own cello case.
* TheyDo: Frank and Ariane are HappilyMarried at the end, as Ariane's father narrates.
* TranslationConvention: The French characters speak English among each other.
* TwinThreesomeFantasy: Frank Flannagan mentions meeting a pair of twins in Sweden. Later, they call him up when they get to Paris.
* WorstNewsJudgmentEver: If the clippings that Ariane seeks out are any indication, the ''entire world'' has nothing to talk about other than Frank's love life.
