Incidentally, since I watched it in German back in the 80s and only in English once I acquired the DVD: this is one well dubbed movie, not least since they took care to let the German voices use Austrian accents. Where you’re always startled out of watching with a downright Brechtian Verfremdungseffekt is when the bits from Entführung aus dem Serail and Zauberflöte are sung, because naturally these didn’t get dubbed, which means you get them in English.
