I was somewhat confused as it appears that Italian director Umberto Lenzi, who will always be known in my book for his notorious cannibal flicks, has two movies that share the same alternative title, and they were only made one year apart. Even on the disc extra he seems a little confused himself when talking about it!
Anyway, this Paranoia is not a horror movie, Furthermore there is no unknown killer, we know who the killer is, but the police don't. So I'd be hard pressed to call this a genuine Giallo, though it certainly has some traits of that sub-genre. As is so typical of Italian movies from this time Paranoia is stunningly beautiful, every scene is like a piece of art. Accompanied by beautiful naked women, fast cars, bottles of J&B whiskey and a jazzy soundtrack this is a very cool movie, with some great plot twists and turns One of the highlights is a fast car ride along a winding road with sharp hair pin turns and sheer drops into the sea. It actually made my palms sweat!
Great movie.
