Peter Falk stars as a Jewish carpet salesman whose wife (Olympia Dukakis) has just left him; accompanied by his middle-aged son (Paul Reiser, who also wrote and produced), he leaves for what proves to be an extended trip to upstate New York in autumn. Falk throws himself into the part and almost single-handedly enables this comedy drama to transcend some of its sitcom limitations. Raymond De Felitta directed; with Elizabeth Perkins. PG-13, 96 min. (JR)
