Bitter Moon is a 1992 Franco-British-American 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 a book with the same name, written by the French author Pascal Bruckner. The score was composed by Vangelis.
A prim and proper British couple, Nigel and Fiona Dobson, are on a Mediterranean cruise ship to Istanbul, en route to India. On the ship, they meet the seductive French woman Mimi and her much older American husband Oscar, a paraplegic: acerbic and cynical, he is jaded and a failure as a writer.
