Die Fledermaus 1972 Synopsis - Witty, fun, intoxicating film of Johann Strauss II's popular operetta, based on a stage production from Vienna State Opera; this is a showcase for the entire cast, but most especially Eberhard Wächter as the insufferably boorish Gabriel Eisenstein, and Gundula Janowitz as his long-suffering wife. Open the champagne, have yourself some torte, and enjoy this delectable comedy from Vienna.
