Before Jean Dujardin, Audrey Tautou was the French flavor du jour with “Amélie” a decade ago. But the actress was back as the toast of New York on Sunday night. Her movie, “Delicacy,” closed the Film Society of Lincoln Center’s “Rendez-Vous with French Cinema,” where she walked the carpet in white Chanel and ruby-red lips. She was also feted at a Soho House reception over the weekend by hosts Charles and Clo Cohen, who are distributing the film.
