Scarlett Johansson and John Travolta promote their film, A Love Song For Bobby Long, which was screened at the festival.
Johansson, who made waves last year with Lost In Translation, is one of the judges at the festival.
The nine-member jury, headed by director John Boorman (Excalibur), also includes German director Wolfgang Beckers, director Spike Lee and actress Helen Mirren.
Robert De Niro -- who is of Italian descent -- will be made an honorary citizen of Italy in one of the festival's highlights.
Johansson, 19, and Travolta, 50, strike a pose.
