Released in the U.S. as Happy Days, Les Beaux Jours was Simone Simon's last French vehicle before she launched the Hollywood phase of her career. The story revolves around the lives and loves of a group of attractive young Parisian students. The most attractive, of course, is our girl Simon, who is wooed by such eligible males as Raymond Rouleau and Jean-Pierre Aumont. The unexpected star of the proceedings, however, is the brilliant pantomimist Jean-Louis Barrault, whose first film this was. Barrault of course was later the star of the wartime classic Les Enfants du Paradis.
