She was the queen of the festival. Parisian-born actress — and local favorite — Marion Cotillard hit the royal runway last week alongside co-stars Clive Owen and James Caan to promote their upcoming big-screen thriller “Blood Ties.” While there was no shortage of elegant ensembles during the Cannes Film Festival’s 12-day run, Cotillard turned heads with her elegant updo and color-blocked dress and heels from the Dior resort ’14 collection.
