The World Will Tremble tells the harrowing true story of the Jewish prisoners who escaped the Chełmno Nazi death camp in Poland and delivered the first eyewitness account of the Holocaust during World War II. Writer/director Lior Geller pulls no punches, recreating in barbaric detail the systemic brutality, mass murder, and vile atrocities of the 20th century’s most horrifying crime against humanity in its nascent stage. The World Will Tremble is a deeply troubling experience that rattles to the core, but must be seen as a reminder of our worst instincts. Geller’s superb camerawork and production design makes up for scenes with questionably written dialogue that unfortunately doesn’t match the realism of the graphic visuals.
