The Cannes Film Festival kicked off with a star-studded opening ceremony that had the red carpet full of famous faces in the French city today. Salma Hayek posed in a gorgeous Gucci Première gown with her husband, Francois-Henri Pinault, on her arm, while model Karolina Kurkova stopped for the cameras solo in a blue Armani Prive. Uma Thurman, in a white Versace number, was accompanied by fellow judges Robert De Niro and Jude Law as they made their way up the grand staircase. Longtime couple Melanie Griffith and Antonio Banderas were also on hand for the start of the festivities, as was international actress Aishwarya Rai Bachchan, who wore Elie Saab. They all made their way inside the Palais des Festivals, where Uma, Jude, and Robert took the stage while Woody Allen and more watched from the audience. The event was just the first of many that will take place in the next week, with expected attendees Brad Pitt, Angelina Jolie, Johnny Depp, Penelope Cruz, and Sean Penn all making their way to the luxurious South of France to join in the fun.
