The Zone of Interest director Jonathan Glazer explains why Hedwig's mother leave the Hoss family home next to Auschwitz. Released in theaters in December after a buzzy premiere at the Cannes Film Festival in May, Glazer's most recent directorial effort follows Nazi commandant Rudolph Höss (Christian Friedel), his wife, Hedwig (Sandra Hüller), and their children as they live their lives next to the Auschwitz concentration camp. Hedwig's mother, Linna Hensel (Imogen Kogge), comes to stay with the Höss family during the film, but she abruptly leaves, writing a note to her daughter.
