Francesco Rosi’s new film of Primo Levi’s The Truce recounts the author’s long struggle to return home after liberation from a Nazi concentration camp. The Long Way Home tells a similar tale, but on a larger scale: This is the documentary of all the Jewish “D.P.s” (displaced persons) after the war, who faced new horrors and additional incarceration as the Allies slowly sorted out the European aftermath. The British attempted to keep European Jews from reaching Palestine, while the United States continued to resist acceptance of Jewish refugees. The establishment of Israel in 1948 brought new hope, but by then many of the war’s survivors had been shuffled around for years under the Allies. Given the subject, Mark Jonathan Harris’ film is drier and less immediate than might be expected. Still, the history it tells is both fascinating and necessary. At 8 p.m. Tuesday, May 5, at the Kennedy Center Opera House. $20 (benefits the Simon Wiesenthal Center). (202) 467-4600. (Mark Jenkins)
