this have be show on late night italian tv some year back and and later and i recall it be mention favorably online while hence and give it theme of an updated version of jack the ripper and the fact that it star euro cult icon paul naschy and i decide to check it out this time around . however and it turn out to be quite a mess represent not so surprising when consider that the only other j. l. madrid film i have watch be the similarly dispirit the horrible sexy vampire ( 1970 ) . while a in that film and the woman here be mainly on screen in order to disrobe and get butcher . the plot provide three possible suspect of the serial killing represent a cripple and bitter ex trapeze artist ( naschy ) whose wife be among the victim and a handsome schoolteacher of noble birth but who actually impotent and and surprisingly and a police commissioner who just happen to be the latter boyhood chum and be also secretly in love with his wife ( orchidea de santis and whom i saw in the flesh and on screen in luciano salce equally obscure but infinitely superior political satire and coup detat [ 1969 ] at the 61st venice film festival ) . the swing london location be just about the only authentic element here represent both the gore and the occasional action scene look extremely phony while another clear measure of the film lack of budget be that naschy accident ( which continue to haunt him ) be hilariously depict simply by have the actor throw himself in front of the camera and utter a couple of none too convincing groan .
