Despite an incredibly stupid English language title ("The Washing Machine"), this is a real return to form both for the Italian giallo genre and for infamous Italian director Ruggiero Deodato. Ironically, Deodato never really directed too many giallo back in their 70's heyday. (He was either making nihilistic Third World cannibal films or being put on trial in Italy or other places for making nihilistic Third World cannibal films). In the late 1980's and 1990's, however, he made two fairly decent ones in a row(after "Stagefright" and "Opera" probably the best two of that period), "Off Balance" in the late 80's and this one a few years later.
This movie is about a cop who is trying to find out which of three sexy prostitute-sisters (a very aggressive one, a deceptively shy one, and a mysterious one in between) was responsible for killing their thuggish pimp. This naturally involves him having sex with all three. The end is not entirely unexpected, but enjoyable nevertheless.
Like Fulci's movie "Aenigma" made a few years earlier this was filmed in Eastern Europe after the fall of the Iron Curtain, obviously in an attempt by the declining Italian film industry to open up new markets, and more importantly, to save money. Unlike with the Fulci film though, the unknown Eastern European actresses here are not only very sexy, but also pretty good (especially the one playing the middle sister). Mostly though it's Deodato's effective directorial style that really does the job. The movie has enough sex in it that it could be mistaken for one of the multitude of "erotic thrillers" that were big at the time (after the success of the Hollywood thriller "Basic Instinct"), but this movie is actually GOOD,and deserves to be included more as a late entry in the vastly superior giallo genre. Anyway, if you like decent gialli, or are willing to see an "erotic thriller" that DOESN'T mightily suck, be sure to see this one.
