Another promising contender is Brian De Palma’s “The Black Dahlia,” with Scarlett Johansson, Hilary Swank and Josh Hartnett, drawn from the James Ellroy novel.

Also competing for the Golden Lion: Alfonso Cuaron’s “Children of Men,” starring Clive Owen, Julianne Moore and Michael Caine; Emilio Estevez’s “Bobby,” with Sharon Stone, Anthony Hopkins and Demi Moore, about the assassination of Sen. Robert F. Kennedy; and Stephen Frears’ “The Queen,” with Helen Mirren, James Cromwell and Michael Sheen.
