The Venice Film Festival is taking a risk this year, presenting nothing but world premieres among the films vying for the fest’s top prize. “Twenty one films will compete for the Golden Lion, which was won last year by Ang Lee’s Brokeback Mountain… Competing films include Bobby, written by actor Emilio Estevez, about the final days leading up to Senator Robert Kennedy’s assassination, and Alfonso Cuaron’s sci-fi thriller Children of Men. Brian De Palma’s The Black Dahlia, also in competition, will open the 63rd festival.”
