'Oh, Rosalinda!' is a very odd film. The last high fantasy from the legendary pairing of Michael Powell and Emeric Pressburger, it's a filmic operetta based on 'Die Fledermaus' and set post WW2 in allied forces occupied Vienna.
It has an all star cast (including Arthur Mullard), great production, an amazing look and is amusing, but was a total box office flop, hastening P & P into a couple of uninspired war films and, in 1957, the dissolution of their incredible partnership.
It's also weird and slightly disquieting, as this short extract should confirm. It was originally filmed in Technicolor Cinemascope, hence the unusual angles of the clip, but the strange perspectives are all Powell, as seen through the bloodshot eyes of Dennis Price (who is not so much acting as just re-enacting his notoriously boozy waking hours on film).
