particular felt that the studio's suggestions would have robbed the film of any drama: "I wanted two people who were perfectly happy. I loved the idea of the totally arbitrary nature of infidelity." The Sumners' relationship was rewritten as a good marriage, with her affair the result of a chance meeting. Pre-production During pre-production, the producers received a videotaped audition from Olivier Martinez, who was selected for Paul. His character was portrayed as French once Martinez was cast.

The director also preferred shooting practical interiors on location so that the actors could "feel an intimate sense of belonging", Biziou recalls. The cinematographer also used natural light as
