I have seen several "giallos", and apart from those by Dario Argento, they can be on the most part, quite dull and routine police dramas. But "What Have You Done To Solange" really surprised me, in fact I would say it's the best non-Argento giallo I have ever seen. A couple taking a romantic boat ride along a river are interrupted when the young woman sees something that frightens her on the riverbank. As she is too disturbed to enjoy the boat trip any more, the afternoon ends on a sour note for the couple, only for them to find out the next day that a brutal murder was indeed commited on the riverbank. Things only get worse from then on.
What I like so much about the film is that the plot unfolds fairly and squarely before your eyes, and you get to see the clues as they appear, the same time as the investigating police do. Unlike some "giallos" where red herrings and ambiguity surround too much of the on-screen action, the clues here are uncovered logically, and you'll find that you take in each new turn of events with growing interest and try to unravel the mystery for yourself. The script and the plot twists are very clever. Very soon after the opening, you learn that the couple on the boat were in fact a married teacher and his female pupil in the midst of an illicit affair, which puts them in trouble straight away as they try and work out how to unravel the mystery without exposing their infidelity. Actually, that's just the very start of their troubles, and I won't reveal any more because I think that everybody should watch this film with as little prior knowledge as possible, and hopefully enjoy it as much as I did.
Beautifully filmed in stunning widescreen, actor Fabio Testi makes for a rather wooden hero, but most performances are good, including a full supporting cast of buxom school girls who put in a lot of full frontal nudity, which should please those viewers watching for some exposure of female flesh. That, and the jaw-droppingly brutal method of murder employed by the killer could have made this film totally depraved, but the stylish plot twists and interesting characters salvage it from being just another piece of Euro sleaze. Set in London, it's particularly nice to see this film with it's soundtrack in English, and the scenes involving the police are often full of very amusing British dialogue. Conversely, Testi's character is an Italian teacher living in England, so he has an authentic sounding Italian accent...it's little things like that that make the difference. Plus watch out for a surprising and effective appearance by Camille Keaton (of "I Spit On Your Grave") towards the end of the film...sorry, but again I can't tell you anymore!
I would recommend this to any Euro horror or Giallo fan. It looks great, has an intrigueing plot and a satisfying explanation to round it off. You'll enjoy it all the way through. But do yourself a huge favour and avoid spoilers!!
