CHiPs, cheese and popcorn! B-movie entertainment doesn't get better than this!
15 March 2015 | by CoventrySee all my reviews

There are movies of which you already know from the very first second that they will provide you with tremendous entertainment and a blast (pun intended) of a good time! The vast majority of these movies are Italian exploitation flicks from the early '80s and yet another large number of them are films directed by Enzo G. Castellari. In the 1970s Castellari made several qualitative cop thrillers ("The Big Racket") and stylish westerns ("Keoma"), but in the eighties he resolutely went for awesome popcorn-flicks like "The Last Jaws", "The Bronx Warriors" and this sadly too obscure "Light Blast". This movie feels like a mixture between a "Dirty Harry" sequel and a car chase thriller, though also spiced with many delightful horror and science-fiction elements. No one other than Erik "Ponch" Estrada (from the success series "CHiPs") stars as a rough 'n tough San Francisco copper on the tail of a mad scientist who threatens to destroy the entire city with his newly invented mega-powerful laser gun. Dr. Yuri Soboda's laser gun definitely works, that's for sure, since we witness how "Light Blast" begins with a lovely demonstration! I'll spare you the technical details, but the impact of the laser beam causes such tremendous heat and radiation that human flesh spontaneously melts away! An innocent young couple painfully experiences this when they're making love in the abandoned factory that Dr. Soboda uses to test his deadly device. He then gives another demonstration at a stock-car race and demands the sum of $10 million or else we'll strike again. "Light Blast" is literally chock-full of zero cool car chases in the bumpy streets of San Francisco, with lots of ravaged vehicles and unfortunate random victims, and during the climax Estrada even drives around in a desert buggy. The film also features many extremely violent shootouts (the bullet holes are huge) and nasty fights. The absolute highlight of the film – next to the face melting effects of course - is perhaps Estrada's encounter with a deranged female undertaker, as she nearly beats him to pulp her mortuary. "Light Blast" stars several memorable villainous characters, in fact. Ennio Girolami is terrific as the psychopathic Dr. Soboda. I bet that Enzo Castellari really wanted to cast Lee Van Cleef for this role, because Girolama looks a lot like him and even imitates his typical evil grimaces. Seriously, if you don't enjoy "Light Blast" you're a true sourpuss and you need to go see a doctor! This movie is just too much fun.
