The guy who played Hoess, the Auschwitz Kommandant, was really good in that too.
Yes Gunther Maria Halmer was great as Hoess. I think Wouk (who also approved the screenplay) with his painstaking research, captured Hoess perfectly. I also thought Topol was great as Berel Jastrow. I believed Meisner made a much better Hitler than Berkoff. Berkoff played an over the top Hitler and was not believable in most of his scenes.
