Fanfan (Fanfan & Alexandre) is a 1993 French romantic comedy film written and directed by Alexandre Jardin and starring Sophie Marceau and Vincent Perez. This film is based on the director's best-selling 1990 novel, which was translated into almost two dozen languages.

Plot

Alexandre (Vincent Perez) is frustrated with his fiancé, Laure (Marine Delterme), whose idea of a romantic Valentine's Day gift is a pair of slippers. The passion and magic of their initial courtship has been replaced by routine and boredom. Needing to get away, Alexandre visits the beachfront cottage of his friends, Ti (Gérard Séty) and Maude (Micheline Presle). There he meets a young woman, Fanfan (Sophie Marceau), who is Maude's granddaughter and a student at Maude's school, studying to become a perfumer or Nose. Although they sleep in the same bed that night, Alexandre avoids any physical contact.

Fanfan

The next day they are joined by Ti and Maude, who become confidants to their guests. Fanfan takes Alexandre to an old, abandoned house where they learn more about each other in the quiet comfort of her life "hideout". Back at his apartment, Alexandre discovers his fiancé in the bedroom dressed as an Italian call girl, hoping the charade will excite his libido and rejuvenate their relationship—but the charade does not work. Later at her parents' house, Alexandre becomes even more discouraged by Laure's father's talk of him joining the funeral business and the gloomy outlook on marriage.

Fanfan

Meanwhile, Fanfan confesses to a friend that she is in love with Alexandre. For Alexandre, however, things are more complicated. He explains to Ti that his past relationships have all followed the same disappointing pattern—the seduction and passion at the start is inevitably replaced with routine and boredom once a relationship becomes sexual. When asked what the alternative is, Alexandre offers his solution: Platonic love. To avoid the banality of "coupledom" in his new relationship with Fanfan, he will court her forever without ever revealing his love for her. He'll never kiss her or take their relationship to a physical level, reasoning that excitement is found in unfulfilled desire. He will stay with Laure physically, but will stay in love with Fanfan forever.

Fanfan

Alexandre and Fanfan meet for a date at a beautiful upscale apartment, which Alexandre says belongs to his father. While Fanfan reveals personal and intimate details about her life, Alexandre prepares all her favorite foods, and the two share a romantic evening by candlelight. The perfect evening is interrupted, however, when the apartment's owner returns home with his wife, who proceeds to call the police as Alexandre and Fanfan make their escape.

Alexandre blindfolds Fanfan and drives her to a television studio to a set designed to be Vienna in 1813. He dresses her in a ballroom gown, removes the blindfold, and they waltz together, gazing lovingly into each other's eyes. They end their magical evening with a bottle of champagne on an imaginary balcony overlooking an imaginary Vienna, with Alexandre proposing a toast to their "friendship". Fanfan is clearly disappointed and annoyed with Alexandre's talk of "friendship", and she asks to be dropped off at the home of her friend Paul—a sculptor doing a nude study of her.

Alexandre returns home to an equally annoyed Laure, who suspects he's been with another woman. Alexandre admits it, but assures her that nothing will ever come of it. As Laure plans out their wedding, Alexandre can actually see them turning into her parents. Laure knows something is wrong, saying, "I wish I weren't yours so you would want me again." Meanwhile, Fanfan complains to Maude about Alexandre's strange behavior. Unlike Alexandre, Fanfan believes in "eternal passion for life." Fanfan learns from Maude that Alexandre has been living with Laure for five years.

Alexandre and Fanfan continue to socialize as friends, but the "friendship" only creates more frustration. They meet at a restaurant and Fanfan gives him an ultimatum: he must choose between Laure and her. While Alexandre claims to want only friendship, Fanfan knows he is attracted to her by his scent. Later when she isn't looking, Alexandre pours sleeping powder in her drink, and she falls into a deep sleep on the ride home. She wakes up on the beach at the cottage, where Alexandre watches over her and applies suntan lotion sensually on her back. Tempted by the half-naked Fanfan, he moves to kiss her when suddenly Laure arrives by boat and announces that the wedding plans are set and that she is pregnant. After congratulating the couple, Fanfan leaves in disgust.
