Banner plays a general or field marshall in this, efficient and
ruthless, so totally different in character from Schultz. Klemperer
plays Eichmann. From imdb:
"The most chilling scene is to see the SS characters of Werner
Klemperer and John Banner (Four years before "Hogan's Heroes") matter
of factly greeting the Jewish arrivals to the death camp. The contrast
between the high comedy of their work together later on belied how easy
a shift of perspective of the Third Reich could be achieved. I
recommend this film just for this extremely chilling scene alone."
