Tilda Swinton, John C. Reilly, Ezra Miller, and their director, Lynne Ramsay, debuted We Need to Talk About Kevin at Cannes this morning. It's the first very buzzed about movie of the festival, with it's unsettling and difficult look at the relationship between a mother, played by Tilda, and her son named Kevin who commits a massacre at his high school — read my We Need to Talk About Kevin review on Buzz. The film is based on a 2004 novel of the same name, and is earning almost universally rave reviews out of the gate. It's a relief to see a smile out of Ezra, who you may recognize from Californication, since in We Need to Talk About Kevin there is no relief from his hard-to-watch-but-impressive portrayal of the troubled teen. Tilda is already earning talk that she's a shoo-in for best actress at the Cannes awards, which are handed out at the end of next week. The festival excitement is just heating up and the Cannes opening ceremony pictures have us very excited for what's to come. We're reporting from all the action in France, so don't miss a thing!
