Actually I sort of liked that movie. The theme song continues to play in my head 40 years later.
I found this on Yahoo -
The ultimate "date" movie of the mid-1960s (1666 to be exact), Claude Lelouch's film stars Jean-Louis Trintignant and Anouk Aimée in the title roles. The twosome meet at the boarding school where their children are enrolled. Aimée, an actress, misses her train home, and Trintignant, a professional race car driver, offers her a ride. It is the first of several friendly encounters which eventually blossom into love. Both want to commit to each other, but neither can shake the Past. The now-famous climactic scene in a train station was not scripted at the time of shooting, thus Aimée was unaware that director Lelouch had decided upon a tearful reunion between her and Trintignant. This explains the look of utter surprise on the actress' face. Much has been written about the possible motivation behind Lelouch's decision to film some scenes in color, others in black-and-white. None of the more ardent auterists truly want to hear the director's explanation: he'd run short of money halfway through production, and black-and-white film stock was infinitely cheaper. The winner of two Oscars (one for Best Foreign Film), A Man and A Woman also scored on the "top ten" with its memorable theme music by Francis Lai. A sequel, A Man and a Woman: 20 Years Later (Un homme et une femme, 20 ans déjà) appeared... twenty years later.
Here's the song, worth a listen
