Requiem

Requiem is a 2006 German drama film directed by Hans-Christian Schmid. It stars Sandra Hüller as Michaela Klingler, a woman with epilepsy, believed by members of her church to be possessed. The film avoids special effects or dramatic music and instead presents documentary-style film making, which focuses on Michaela's struggle to lead a normal life, trapped in a limbo which could either represent demonic possession or mental illness.
