Though made in Germany, this film version of Johann Strauss’ comic opera Die Fledermaus was distributed in the U.S. by the Russian firm of Artkino. Such full-throated singing personalities as Marte Harell, Johannes Heesters, Willi Dohm and Haus Brauseweiter go through the time-honored paces of the opera’s libretto, wherein an upper-class Viennese gentleman simultaneously tries to avoid arrest and to prove his wife’s fidelity.
