Manon 70

Manon 70 is a 1968 French (French-Italian-German co-production) drama film directed by Jean Aurel and starring Catherine Deneuve, Jean-Claude Brialy and Sammy Frey. It was written by Aurel with Cécil Saint-Laurent. The story is loosely based on "Manon Lescaut", an 18th-century French novel by Antoine François Prévost. The original music was composed by Serge Gainsbourg.
Synopsis.
Manon (Catherine Deneuve) is an amoral, free spirit who uses sex to surround herself in relatively luxurious surroundings. Journalist François (Sami Frey) sees her at the airport and falls in love with her. Once they land in Paris, he makes his move and steals her from the man she's been traveling with. François and Manon fall in love but Manon's brother (Jean-Claude Brialy), wants to live off his sister and causes trouble. Manon tries seeing a wealthy man (Robert Webber) at the same time as Francois.
Reception.
Deneuve later said she wanted to work with Jean Aurel because she like his film "In Love". Of "Manon 70" she said "the story was great but the film just missed... it's probably because the director was not at his best."
