Miles Davis recorded the music with a quartet of French and US musicians in a few hours (from 11pm to 5am one night), improvising each number and allegedly sipping champagne with
Jeanne Moreau and
Louis Malle.
Louis Malle shot his lead actress
Jeanne Moreau in close-up and natural light and often without make-up. Moreau, an icon of French film, had never been seen like this before, to the extent that lab technicians, reportedly appalled at how unflatteringly she was photographed, refused to process the film. Once they were persuaded to, however, it soon began clear that Malle had captured every nuance of Moreau's performance.
