Le Combat Dans L’ile (French, 1962)
Director: Alain Cavalier
With: Romy Schneider, Jean-Louis Trintignant, Henri Serre, Diane Lepvrier, Pierre Asso
French “new-wave” film noir. Very atmospheric and moody, and a political subplot. Clement (Trintignant) is a right-winger who belongs to a shadowy group planning an assassination. He is married to Anne, an arty and naive woman who is growing disillusioned with him and her marriage.
After the assassination attempt, Clement is betrayed by Serge (Asso), and takes it upon himself to hunt the man down and kill him for his betrayal. He leaves Anne with an old friend Paul (Serre), who lives in the country and is a left-liberal.
