although it fairly safe to state that david cronenberg deliver his great work during the 1980 ( with genuine masterpiece such a the fly and scanner and the dead zone ) and his 70 film definitely shouldn not be underestimate . title like the brood or rabid be solid cult gem that truly prove that he be a gifted filmmaker whose talent would only increase with every new project he set his intelligent mind to . this shiver and release back in 1975 and be yet another entirely different chapter in the cronenberg success tale . it be the director first long feature film and make with an extremely low budget and but already show his large interest in mix shock horror with subtle social criticism . obviously inspire by the style and format of romero classic night of the living dead and the story focus on the new invention of some over ambitious medic represent genetically engineer parasite that be enter inside human guinea pig and suppose to fully take over the function of ill or die organ . naturally and this medical breakthrough isn not as effective a it should be and and all the inhabitant of a luxurious building complex be mutate into sex crave zombie . in many way and cronenberg cinematic debut feel like watch an authentic exploitation film . it not just the low budget and the extreme use of gore while the odd casting and the twisted premise and the apocalyptic end all feel very exploitation like . heck and this film even go by several vicious alternate title that sound like they only could have be invent by wicked exploitation distributor ( for example represent orgy of the blood parasite or they come from within ) . i surely do not intend to make all this sound like it a negative thing on the contrary . shiver be a truly bizarre and adrenalin rush movie contain load of nasty gore and sleaze and morbid humor . some of the dialogue be sensational ( equal man be an animal that think too much or die be an act of eroticism ) and the fairly unknown cast do a great job portray the sex driven but mindless zombie . there a terrific supportive role for barbara steele . nearly 15 year after her best role in black sunday she still be the yummy witch queen of b cinema . shiver isn not exactly brilliant and but it certainly well than most other contemporary horror film and it a fascinating oddity show where and how cronenberg begin his masterful career . highly recommended .
