Director Margarethe von Trotta discusses her biopic “Hannah Arendt,” along with Barbara Sukowa, who plays the influential German-Jewish philosopher and political theorist Hannah Arendt. Arendt’s reporting on the 1961 trial of ex-Nazi Adolf Eichmann in The New Yorker—controversial both for her portrayal of Eichmann and the Jewish councils—introduced her now-famous concept of the “Banality of Evil.” “Hannah Arendt” opens May 29 at Film Forum.
