Bitter Moon (IMDB) is a 1992 erotic/romance film, directed by the notorious Roman Polanski, based on the novel Lunes de Fiel by Pascal Bruckner
Nigel goes on an ocean cruise with his wife, Fiona, where he becomes fascinated by a beautiful, mysterious woman named Mimi. Her husband, a paraplegic would-be writer named Oscar, demands that Nigel listen to his story of his obsessive love with Mimi before Nigel has an affair with her. Like another tale of twisted love, Nabokov’s Lolita, we shouldn’t take the narrator at face value. Mimi privately tells Nigel: “You musn’t believe all he says. He’s a sick man. He imagines things.”
In Oscar’s story, he is a self-consciously literary archetype, an independently wealthy young American living in Paris to become a writer. On a bus trip, he becomes smitten with Mimi, a young French woman.
Mimi is a cipher, with almost nothing more to her than being a beautiful French dancer, at least in Oscar’s telling. The early stages of their romance go from sweetly romantic to an adolescent’s idea of eroticism.
Oscar: (to Nigel) “I’m only going into such detail to show you how completely enslaved I was, body and soul, by this creature whose dangerous charms have made such an impression on you.”
