Salon Kitty (1976)
Italy/West Germany/France co-produced Nazisploitation, directed by Tinto Brass, and starring Helmut Berger. Ingrid Thulin, and Teresa Ann Savoy.
It's loosely based on the true story of the 1939 'Salon Kitty' operation, in which the SS took over a Berlin brothel, and replaced all the 'working girls' with girls (made auxiliary members of the SS) specially selected and trained by themselves. The intention was to catch clients saying things in 'unguarded moments', perhaps giving themselves away as spies, or at least disloyal to the Nazi cause.
It's a weird mixture of musical numbers, comedy, a lot of softcore, intermixed with scenes of cruelty, murder, and suicide; think a serious WWII drama, mixed in with Cabaret, Springtime for Hitler, Monty Python, and Benny Hill.
Visually the film is very good. The sets look far more expensive than than they probably were (production designer Ken Adam - perhaps most famous for the Bond movies - was desperate for something lighter and more fun after the stress of working for Stanley Kubrick on Barry Lyndon!), and the costuming is perfect (from the immaculate Nazi uniforms, through the clothes of various people struggling to get on with their ordinary lives and just survive the war, to the more 'casual' apparel of the girls).
Berger, Thulin, and Savoy are very good, as is giallo regular John Steiner - almost unrecognisably clean-shaven and short-haired - as a very senior (and fencing-obsessed) Nazi officer.
The uneven tone does jar a bit, and it certainly didn't need to be over two hours long, but this was more (bizarrely) enjoyable than I expected. 6/10
