The American Film Institute theater sputters back to life this weekend with two screenings each of two films. Tonight and tomorrow at 6:30 p.m., Roberto Rossellini’s son Gil introduces a new print of his father’s rarely seen 1958 documentary India, a landmark in the neorealist director’s career. And both nights at 8:30 p.m., Hungarian director Sándor Simó introduces his new film, Every Sunday. Proof that distinctive filmmaking continues in the countries of the former Soviet bloc, Simó’s film examines Hungarian history in the form of a female servant who becomes an agent for the AVH (Hungary’s equivalent of the KGB) after the Communists assume power. At the Kennedy Center’s American Film Institute Theater. $6.50. (202) 785-4600. (MJ)
