Spain's San Sebastian Film Festival Monday turned to the Holocaust with Paolo Barzman's searing "Emotional Arithmetic" about three friends who are reunited decades after meeting in a Nazi concentration camp. The movie, based on a novel by the late Canadian author Matt Cohen, revolves around a middle-aged woman, played by Susan Sarandon, who catches up with two fellow survivors of Drancy--a transit camp outside Paris--in Quebec some 40 years later.
