Severin’s extravagant four-film six-disc Umberto Lenzi / Carroll Baker Giallo Collection is a luxurious trip into sexy, violent Italo thrill territory. CineSavant concentrates on the first Lenzi-Baker collaboration, a truly nasty bit of misanthropy that bridges the gap between standard ‘Lady In Peril’ fare and the full-bore giallos that would soon become the norm. It’s presented under its admittedly attention-getting original title, that sounds more appropriate for a porn movie. In the U.S. the given title was Paranoia — not to be confused with Hammer’s Paranoiac or Lenzi’s follow-up A Quiet Place to Kill, which was also titled Paranoia. With Lou Castel, Colette Descombes and Tino Carraro. On Blu-ray from Severin Films.
