Leave it to the Italians to come up with one of the most engrossing, cheesiest and outrageously entertaining splatter flicks of the 80s! Umberto Lenzi, here under his favorite pseudonym Harry Kirkpatrick, wrote the fantastically bonkers script but offered the director's chair to his lesser known buddy Vittorio Rambaldi. "Primal Rage" is as eighties as it gets: the über-cheesy and misfit pop song "Say the Word" doesn't just feature once or twice but three times integrally, there are loads of beautiful girls with humongous hairdos and sexy aerobic outfits and even the obsessive evil scientist sports a ridiculous little mullet-ponytail! There were quite many horror movies with monkeys during the late 80s, but unlike you'd suspect from Lenzi, "Primal Rage" isn't a clone of "Monkey Shines", "Link" or "Shadow of Kilimanjaro". Dr. Ethridge is working at a Florida University campus and uses a baboon as guinea pig for his research involving brain diseases, but he accidentally saddled the poor animal up with a virus that invokes rage and rabies. When the rebellious campus reporter Frank Duffy breaks into Ethridge's laboratory, he releases the baboon but gets bitten and thus contaminated with the virus. Duffy passes forward the virus to a cute girl he met during a blind date and she, at her turn, contaminates a trio of vicious rapists. Each virus carrier goes on his/her own killing spree during the night of the annual campus Halloween party. "Primal Rage" is clichéd, derivative and predictable, but oh-so-entertaining! The film is fast-paced and features terrific make-up art as well as countless of gory highlights, including beheadings and impalements. Hunky 80s kid Patrick Lowe is rather annoying, but the rest of the cast is decent, with young and yummy actresses Cheryl Arutt, Sarah Buxton and Jennifer Hingel. Naturally, of course, it's Bo Svenson who steals the show as the fanatic scientist (with ponytail). Special kudos for the creative minds who thought up and designed all the dozens of great costumes that people are wearing during the Halloween party! I honestly never saw any cooler or creepier horror costumes in my life.
