Former Mr. Universe Mickey Hargitay was already a sleaze favorite for his turn as Il Boio Scarlatto and his disingenuously tearful tour of his late wife's estate in The Wild, Wild World of Jayne Mansfield. Hargitay only solidifies that image here as Prof. Herbert Lyutak, a perverse sex maniac employed as a criminal psychologist. Lyutak is first seen giving a young woman a ride in his car, eventually attacking her and chasing her through the woods to a creek, where he beats her to death. Lyutak's wife (Rita Calderoni) finds his bloody shirt, but because there is another murder while the demented shrink is consulting the police, he is cleared. Working with the authorities, Lyutak has a family friend (Katia Kardinali) pose as a prostitute to catch the killer, but he simply murders another hooker not far away. The bodies continue piling up, with so many alibis and confusing contradictions that it soon becomes apparent the killings are the work of several hands. Polselli keeps the sleaze factor high throughout, notably in some psychedelic nightmare sequences featuring Lyutak's fantasies of torturing nude women in his basement and in the murder of Kardinali, which features some fairly graphic whipping and kinky sexual allusions. There's also lesbianism, strangulation, and an interesting synth-rock score by Gianfranco Reverberi to keep viewers interested, and the ultimate conclusion is -- in keeping with the title -- a delirious, bloody battle between three psychopaths in a cellar. That's only in the original version, however, because the American re-edit removed most of the sleaze, changed the setting from England to the United States, and added two extra murders and a police shootout, not to mention some dubious Vietnam flashbacks. The ultimate entertainment value to genre enthusiasts, therefore, is highly dependent on which version they see, as the extensive changes reduce a wild, flamboyant shocker to just another dull mystery. Gaetano Cimarosa and Stefano Oppedisano co-star.
