Michael Powell and Emeric Pressburger have shifted this lively and engaging Strauss operetta to the scenario of post WWII Vienna and that allows for some pretty potent language from the top of his game Anton Walbrook's "Dr. Falke" delivering us a slightly more relevant critique of politics, hope, friendship and honour than might have emanated from the original timeframe. The thought of such monologues might be a little off-putting at first, but they are littered with powerful and emotionally charged messages that compliment really well the musical powerhouse that is "Die Fledermaus". On that latter front, Michael Redgrave ("Col. Eisenstein") impresses with his singing and his dancing; Dennis Price features sparingly but effectively as "Maj. Frank" and P&P regular Ludmilla Tcherina actually glows as she takes on the title role with a subtly alluring and charming style. It's colourful, always busy but never rushed and the characterisations evoke a smile and a grimace every now and again as we try to discover just whom is cheating - or wants to cheat - on whom! If you've seen it on stage then it may not compare so well - it does lose some of the intensity of the live performance and Anthony Quayle ("Orlovsky") just never quite did it for me when charisma was required. The remainder of the assembled cast work well with the memorable score and the pristine imagery ensuring this is a challenging but rewarding film to enjoy.
