A Hungarian-language film loosely based on the 1883 operetta Eine Nacht in Venedig (A Night in Venice) by Johann Strauss II. The film was shot simultaneously while making the German film A Night in Venice (1934). The Hungarian version was co-directed by Robert Wiene and Géza von Cziffra and used a separate cast of Hungarian actors. From Wikipedia.
