The lure of family mysteries lies at the heart of “Still Life In Lodz,” an emotionally riveting documentary that journeys to the historically tumultuous city of Lodz, Poland. Here, a surprise reunion with a painting that hung in the same apartment for 75 world-altering years becomes a probing investigation into the power of memory, art, time and resilience. What follows is a deeply personal detective story rich with twists and turns. But, equally it is an ode to the lost generations of Jewish Lodz and a look at how fragile—but also how incredibly necessary—our relationship with the past is for creating the future.
