(Relaxnews) - Directed by Karl Lagerfeld, "Once and Forever" takes viewers behind the scenes during the making of a biopic on Gabrielle Chanel

Starring Kristen Stewart and Géraldine Chaplin -- who both play Gabrielle Chanel at different points in her life -- alongside a supporting cast that includes Jérémie Elkaïm, François Marthouret, and Amanda Harlech among others, the film will get its world premiere in Rome on December 1.

For those that can't get a ticket to the event or that can't get to Italy in time, the film will also debut on Chanel's own digital platform simultaneously.
