Spirited comedic operetta set in 1925 as a high society woman's husband meets her ex-husband for a major business deal while each unaware she had previously married the other. I don't like musicals as a rule but when a cast shows a level of commitment on par with Chicago or Moulin Rouge then I capitulate. This cast surely had to know their stuff on par with a true live show performance as the very long takes and pinpoint timing must've required many many hours of rehearsal. Audrey Tautou sparkles as a supporting character and comes in 5th or 6th in screen time, while it's Isabelle Nanty playing her older sister who gets the best lines, sometimes speaking directly to camera and the audience. Script includes some witty satirization of art movements and the people who only follow the hottest trend, for example the hot ticket is for a new ballet with a seal as the leading dancer, and Cubism has been supplanted by Spherism.
