Famous lecturer Jean Desailly (of a couple Melville films) picks up stewardess Francoise Dorléac (a couple years before Cul-de-sac) and talks endlessly about Balzac at the bar. He falls for her, but is married, and the whole movie is about how hard it is to have a secret affair. It’s even harder because he’s well known, but he acts like Francoise has no other options, and is a pain in the ass to her for almost their own relationship, so when he finally proposes, she breaks up with him. And then his wife finds out.
The music took the whole thing seriously from the start. It’s a suave, smooth looking movie, each scene patiently revealing. A jump cut or two just to remind us this is the FNW, overall more admirable than any fun to watch.
