YOUNG ONES: Front row at Chloé Monday was like a showcase of young French acting talent. A peroxide-blonde Cécile Cassel said she is busy working on Hugo Gélin’s first film, “Comme des frères,” in which she stars with Nicolas Duvauchelle. It’s due out in the fall. Hafsia Herzi, meanwhile, revealed she would like to move behind the camera. “I’m working on a feature film I hope to direct. It will be a fairy tale,” said the actress, who has already directed one short movie. Ana Girardot divulged she’s a little nervous ahead of the première of her film “Cloclo” that night. Marine Vacht, Joséphine de la Baume and Arly Jover were also in attendance.
