Delirium (1987)

As genres, the slasher and the erotic thriller share plenty in common, including a firm grounding in brutal realism. That is to say, the murders and the gore and the sex and the nudity are presented as-is with little ambiguity. Delirium, a 1987 giallo that incorporates elements of both the slasher and the erotic thriller in depicting a series of centrefold murders, breaks with this trend, presenting some crucial killings in surrealist fashion. In these scenes, Delirium follows the slasher trope of moving into the first-person perspective of the killer, but this point-of-view is, contra that of Halloween or Friday the 13th's antagonists, wracked with bizarre hallucinations. As the killer stalks after victims, the entire screen pulsates red and black; when the victims come into view, their faces are monstrous–by turns Cyclopean and theriomorphic. This imaginative depiction of the killer's psychotic, chimerical delusions marks Delirium as truly inventive across a pair of genres typically resistant to innovation. But this is not the only virtue of Delirium. The film is also a cinematographic marvel from start to finish, with intricate, luminous interiors and vast, palatial exteriors. The affluential aesthetic is realized entirely through visuals. Your reviewer supposes that he is expected to say something to the effect of "but no visual is more aesthetically pleasing than leading lady Serena Grandi," but he will not. Grandi's sex symbol status precedes her, at least in Italy, so it needn't be restated (see picture). Rather, it should be said that Grandi brings an unassuming warmth and earnestness to the protagonist's role, culminating in a human grace that transcends her statuesque physique and tameless, oft-exposed bust. You empathize with her character for the trauma she's experiencing due to the loss of her colleagues and family members, and not just for the backpain she's likely experiencing on account of her Brobdignagian bosom. Despite all it's merits, however, Delirium is not without its flaws: as is typical of an Italian film, it features some improbable plot developments and sketchy redubbing. Perhaps most disappointingly, the aforementioned surrealism is only overt in the first two kills, and tapers off as the film reaches its climax. Nonetheless, Delirium's replacement of realist brutality with vivid glimpses into the schizoid visual field of a psychopathic killer makes the film a refreshing take on the slasher/erotic thriller.
