Oh... Rosalinda!! (1955) "Die Fledermaus" (The Bat) is the pseudonym adopted by Dr Falke. Floating on the buoyant waltzes of Strauss, this Viennese romp is sure to please. Disguises, tricks and every kind of deception combine to reveal a would-be cheat in hot pursuit of his own wife, much to his chagrin. Silly, charming, always entertaining, always fun. This is a film version of "Die Fledermaus" set in post-war Vienna with the main protagonists of Dr Falke represented by the 3 occupying powers. This is NOT just a film of a staged production but a truly filmic version of the operetta.
