Pacino plays a small-town locksmith with a key for everything except his own unhappiness in David Gordon Green's "Manglehorn," one of 20 films competing for the festival's top prize.
And he's an aging actor who has lost his mojo in Barry Levinson's "The Humbling."
In both, he's shambling, disheveled and drawn. In Venice on Saturday he was black-clad, sharply coiffed and every bit the movie star.
He said the demands of acting grew tougher with age, but he felt lucky to have "found something in life that I love to do."
