Directors Petra Epperlein and Michael Tucker join us to discuss their film, "Karl Marx City." Their film follows Epperlein as she goes looking for answers after her father's suicide, and investigates letters accusing him of a secret life as an informant for East Germany's secret police. "Karl Marx City" opens March 29 at the Film Forum. Petra Epperlein & Michael Tucker will participate in a Q&A for the 7:00 p.m. shows on March 29 and 31, and the 4:40 p.m. show on April 1.
