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 (Hugh Grant) and Fiona Dobson (Kristin Scott Thomas), are on a Mediterranean cruise ship to Istanbul, en route to India. On the ship, they meet the seductive French woman Mimi (Emmanuelle Seigner) and her much older American husband Oscar (Peter Coyote), a paraplegic: acerbic and cynical, he is jaded and a failure as a writer. The story unfolds as Oscar invites Nigel to his cabin, and tells him in great detail how he and Mimi first met on a bus in Paris and fell passionately in love.
