The casket used in Christoph's apartment was a "loaner" model, borrowed from a local funeral home. Several times during production, it had to be returned for a few days, in order for it to be used to display a body during a funeral service.
The long black leather coat worn by Christoph during the second part of the film is a genuine World War II Nazi great coat.
The clock in Christoph's apartment, as well as his wristwatch, read "6:41". The month and year that Auschwitz opened.
The speech Christoph gives in the Blood Bar, when he is drunk, is from a speech that Adolf Hitler gave to the German people on the morning he invaded Poland.
A staple of the craft services lunch was salad and hoagie sandwiches, dubbed affectionately by the cast and crew as "Sang-whiches".
