Referential? You've got to be kidding. Start with Peter Ustinov's The Love Of Four Colonels than throw in a 'borrowing' from Max Ophuls' La Ronde, made more blatant by employing the same actor Anton (Tilly)Walbrook to do the narration-to-camera. As if do divert attention from the plagiarism Powell and Pressburger cheerfully own up to taking Die Fleidermause and 'updating' it to the immediate post-war Vienna, still divided into four sections and ruled by four powers. For me, Michael Redgrave was the selling point though Iconcede that for others it may have been the Strauss operetta - it's hard to see Mel Ferrer being a draw. Whatever, it's a sort of soufflé manque and amusing in parts.
