Sacha Baron Cohen, as the title character from his movie The Dictator, arrives at the Cannes festival on a camel, of course. Settled in, he and his “girlfriend,” George Clooney’s ex, Elisabetta Canalis, engage in some sexual behavior on a yacht before he kills her, then has her put into a bodybag and thrown overboard. We love the effort and spectacle Cohen puts into a big production when he’s promoting a film. We wish more stars would do it.
