Je Serai Seule Apres Minuit (aka I'll Be Alone After Midnight) (1931)

To get revenge on her philandering husband (Roger Blum), a wife (Mireille Perrey) decides to take a lover for one night. To this end, she sends off a barrage of balloons over Paris attached with a note stating, "I'll be alone after midnight" along with her name and address. Based on a novel by Albert Jean and directed by Jacques De Baroncelli. Co-written by Henri Georges Clouzot (LE CORBEAU), this is an enchanting musical (songs by Philippe Pares and Georges Van Parys). It may be a slight piece of musical French fluff but De Baroncelli's direction breezes it along and it's easy to fall under its romantic sorcery. Nonsense really but served up with such charm that it's near irresistible. I don't want to oversell it, it's not a "must see" but it's witty and sexy and you could do a lot worse. With  Pierre Bertin, Vanah Yami, Maurice Remy and Georges Bever.
