This Spanish Giallo contains suspense , thrills , chills , intrigue and plot twists . In this peculiar version of the famous story of the London serial killer set in contemporary time , here Jack the Ripper not only likes to kill prostitutes but also other beautiful women . Naschy movie with usual elements of the ¨Gialli¨ sub-genre : suspenseful intrigue , twisted killings executed by a brutal killer , violence , sadism , physical abuse , sensationalist murder pieces and nudism . Dealing with a series of murders are happening in London , these killings seem connected to a hunk gammy named Bruno Dorlani (Paul Naschy or Jacinto Molina). The frustrated and bitter ex-acrobat Bruno tries to exculpate himself by sending a letter to the police superintendent via his friend (Patricia Loran) , resulting in fateful consecuences . Meanwhile , the police commissioner , Inspector Henry Campbell (Renzo Marignano) and his agents are investigating the heinous crimes , helped by a handsome schoolteacher of noble birth called Winston Darby Christian (Andrés Resino) married to a beautiful wife (Orchidea De Santis) , all of them being drawn into a twisted criminal plot and hot on Bruno's heels as prime suspect , as they can bring down the killer to the justice .
This is the typical European co-production , a giallo style which copies usual ingredients with a number of suspect people , red herrings and grisly murders against unfortunate victims , being committed by an unknown assassin who executes macabre killings on the body his victims by slashing , cutting or hacking . This is a whodunit in which there are various suspicious people who , as usual , happen to be the protagonists , as the main question of the movie results to be to find out the following : who is the murderer ? .There're various candidates, it may be a wise , well-considered teacher (Andrés Resino) or his vindictive spouse (Orchidea De Santis) or a lame former trapeze artist (Paul Naschy or Jacinto Molina) whose wife is among the victims or even the commissioner Inspector Campbell (Renzo Marignano) himself . Lurid and gut-wrenching criminal drama made during the Francoist period in which abounded co-productions especially in horror and Spaghetti Western genres . As in Terror genre excelled Jacinto Molina who created his particular style where most of his raids would be perpetrated by the emblem of his own company in Spain , this actor, screenwriter and director Jacinto Molina - Paul Naschy , at times , collaborated with writer/filmmaker José Luis Madrid ; the result of whose collaboration are 'Jack the Ripper of London / Sette Cadaveri per Scotland Yard' (1971) and crimes of 'Petiot' (1972). Here Paul Naschy is an ex-circus artist who helps his friend a police inspector to discover who is the ominous murderer , resulting in himself to be the prime suspect . Filmmaker José Luis Madrid designs an average thriller , including some regularly staged murders plenty of startling visual content with blood similar to tomato and adding gore scenes , as well as brief nakedness, though in Spain it was submitted to limited censorship.
It contains atomspheric cinematography by cameraman Diego Úbeda , showing Swinging London locations from the Seventies , as well as some Madrid places , though a perfect remastering being extremely necessary because of the film copy is worn-out . Along with thrillling and intriguing musical score by Italian composer Piero Piccioni , an expert on Giallo soundtracks . The motion picture was regularly directed by José Luis Madrid. He was a craftsman who directed all kinds of genres. As he made Españoladas such as : ¨Lucecita¨ or ¨Strip-tease a la Inglesa¨ ; Spaghetti/Paella Westerns such as ¨The Ballad of Johnny Ringo¨ , ¨Seven Jackals¨, ¨The revenge of Clark Harrison¨ , ¨A Tomb for an outlaw¨; Eurospy movies such as : ¨Chineses and minishorts¨, ¨Ok Yetvtushenko¨ ; Crime movie such as ¨The Hyena¨ , and for the famous Spanish Werewolf , Paul Naschy , directed 2 movies : ¨Jack Ripper of London¨ and ¨Crimes of Petiot¨ and political/historical films such as : ¨Memorias del General Escobar¨ and ¨Command Txiquia¨ concerning the assassination of President Carrero Blanco . He also worked for the powerful German producer Arthur Brauner from Constantine Films with whom José Luis Madrid made a lot of uncredited films . Most of them were Krimis , a subgenre very popular in Germany . Throughout his long career he also showed a sense of opportunism with sensationalistic productions , such as : ¨The motorway Vampire¨ , about a vampire killer and ¨Last Tango in Madrid¨, there badly imitating ¨Bertolucci's Last tango in Paris¨. Rating : 5.5/10 . Average but passable Giallo .
