Matt Damon and his wife, Luciana, took their girls for a sunny outdoor lunch at the Eden Roc Hotel in Antibes, France, yesterday. Matt sipped white wine and shared a sweet moment with his daughter Gia, showing her the water and pointing out some sights. Matt brought his clan along to Cannes while he promotes Behind the Candelabra, which debuts on HBO this Sunday. The family lunch was just part of a busy day for the actor — he attended a photocall for the film with his costar Michael Douglas and later hit the red carpet with Luciana for the movie's premiere, where he snapped photos of all the fun on his cell phone. In addition to his small-screen project, Matt has also been busy promoting the upcoming sci-fi flick Elysium. He screened trailers for the blockbuster in Mexico and Berlin late last month and will likely make the rounds with costars Jodie Foster and Diego Luna before the film hits theaters in August.
