'What Have They Done To Our Daughters?' is an above average giallo directed by Massimo Dallamano, who was the cinematographer for Leone's spaghetti western classic 'For A Few Dollars More'. It's a kinda sorta sequel to 'What Have They Done To Solange?', which I haven't seen. But I have seen Dallamano's swinging De Sade 'Venus In Furs' and both movies have made me very interested in his work. The story concerns a police investigation into the shocking murder of a teenage girl which uncovers a prostitution ring. It stars Giovanna Ralli who was in another pretty good giallo 'Cold Eyes Of Fear' and Claudio Cassinelli who co-starred in the nunsploitation classic 'Flavia The Heretic'. It's also quite a surprise to see Farley Granger (of Hitchcock's classics 'Rope' and 'Strangers On A Train') in the supporting cast, though his performance is forgettable. Giallo fans will enjoy this one, but if you are new to genre try some Dario Argento (especially 'Tenebre') or Fulci's 'Don't Torture A Duckling' to see some of the best examples of this style of thriller. Still, this is a pretty good movie with some gruesome and sensationalistic touches.
