Who is the deranged maniac persecuting and mentally torturing celebrated rock musician Roberto Tobias? First he’s implicated in a horrifying stabbing, and is soon surrounded by more senseless slaughter. The last strange image captured on one murder victim’s eye retina contains the only clue to the demented criminal manipulator. And their identity will take Roberto over the edge of sanity to a shock horror peak in Dario Argento’s classic Giallo chiller. This homicidal frenzy completed Argento’s revered ‘Animal’ trilogy (alongside The Bird with the Crystal Plummage and Cat O'Nine Tails) that dubbed him ‘The Italian Hitchcock’, leading to 'Suspiria' and his worldwide ‘Master of Horror’ reputation. Argento’s unmistakable flair for creating fear in lavish style is on stunning show in this slick, sick primal scream – with a shattering slow­motion climax given further operatic violence by one of genius Ennio Morricone’s most memorable scores.
