Bitter Moon is a 1992 Franco-British-American erotic romantic thriller film directed by Roman Polanski and starring Hugh Grant, Kristin Scott Thomas, Emmanuelle Seigner and Peter Coyote. The film is known in France as Lunes de fiel (a pun on the French phrase "lune de miel", meaning 'honeymoon'). The script is inspired by the novel Lunes de fiel, written by the French author Pascal Bruckner. The score was composed by Vangelis.
British couple Nigel (Hugh Grant) and Fiona Dobson (Kristin Scott Thomas) are on a Mediterranean cruise ship to Istanbul en route to India. They encounter a beautiful French woman, Mimi (Emmanuelle Seigner), and that night Nigel meets her while dancing alone in the ship's bar. Later Nigel meets her much older and crippled American husband Oscar (Peter Coyote), who is acerbic and cynical, having been jaded and a failure as a writer.
