Boasting 28 films from ten nations, the fifth annual festival offers a mix ranging from the French comedy Dad on the Run, a zany tale about the rituals surrounding Sephardic circumcision, to the Italian drama The Sky Is Falling, starring Isabella Rossellini as the matriarch of a happy family in 1944 whose tranquil lives are marred by the war. Documentaries and short films will be screened; a few panel discussions are planned, as are pre- and post-film talks with nine directors, including Francis, who will appear Saturday night. The vision of artistic director Florence Kaufman, the festival, presented by the Central Agency for Jewish Education, is not aimed solely at Jews but at South Floridians of every stripe grappling with the puzzling American experience that is assimilation.
