Review by Bunuel1976

This had been shown on late-night Italian TV some years back and, later, I recall it being mentioned favorably online; hence, given its theme of an updated version of Jack The Ripper and the fact that it starred Euro-Cult icon Paul Naschy, I decided to check it out this time around. However, it turned out to be quite a mess: not so surprising when considering that the only other J.L. Madrid film I've watched was the similarly dispiriting THE HORRIBLE SEXY VAMPIRE (1970)!; as in that film, the women here are mainly on screen in order to disrobe and get butchered.

The plot provides three possible suspects of the serial killings: a crippled and bitter ex-trapeze artist (Naschy) whose wife is among the victims, a handsome schoolteacher of noble birth but who's actually impotent and, surprisingly, a police commissioner who just happens to be the latter's boyhood chum and is also secretly in love with his wife (Orchidea De Santis, whom I saw in the flesh and on screen – in Luciano Salce's equally obscure but infinitely superior political satire, COUP D'ETAT [1969] – at the 61st Venice Film Festival)!

The Swinging London locations are just about the only authentic element here: both the gore and the occasional action scene look extremely phony; another clear measure of the film's lack of budget is that Naschy's accident (which continues to haunt him) is hilariously depicted simply by having the actor throw himself in front of the camera and utter a couple of none-too-convincing groans!
