The Cesar-winning actress also stormed the red carpet in another way when she teamed up with Blanchett and DuVernay on Saturday for a march highlighting the lack of female directors included at Cannes over the years. The ban caused stars to speak out against the guidelines, with British actress Emily Blunt saying the alleged ban was "very disappointing". "Does he have to wear heels?'"
