“Broken Silence” is composed of five hourlong shorts from a quintet of international directors: Hungary’s Janos Szasz (“Eyes of the Holocaust”),Argentina’s Luis Puenzo (“Some Who Lived”),Russia’s Pavel Chukhraj (“Children From the Abyss”),the Czech Republic’s Vojtech Jasny (“Hell on Earth”) and Poland’s Andrzej Wajda (“I Remember”). The helmers, some descendants of Holocaust survivors, focus on the atrocities within their particular parts of the world, with testimonials, pictures and an overall tone as they pertain to each region’s culture and history.
