Genghis Cohn (1993)

In the midst of World War II, Nazi officer Otto Schatz declares the execution of Jewish music-hall comedian Genghis Cohn. Many years later, Otto is comfortably retired into the life of a highly respected police commissioner, and is investigating a series of murders when he encounters the ghost of Genghis Cohn. The haunting turns into a taunting, and before he knows it, Schatz is slowly driven mad as he is lured into a trap.
