Like none of his other late 50's/early 60's horror & Sci-Fi tryouts (and there were quite a lot of them), "The Wasp Woman" truly proves that Roger Corman was, and still is, a very creative and versatile filmmaker! The plot of his ultra-low budget quickie is mundane and unbelievably predictable, yet the whole film is stuffed with ingenious little twists and elements that make the premise feel fresh and original nevertheless! There are very few directors out there, apart from Corman, able to achieve this! Susan Cabot, who starred in a handful of contemporary Corman productions, plays a businesswoman leading a prominent cosmetics company. She's unable to accept her own natural ageing process and righteously fears that her looks will bring down the monthly profits. When a scientist announces that he developed a rejuvenation liquid by extracting enzymes of ordinary wasps, Janice Starling immediately wants to commercialize it and test it on herself. The miraculous discovery is highly efficient, but when Janice injects herself with too much doses, she transforms into a murderous wasp overnight. "The Wasp Woman" is no more or no less than fun & undemanding Sci-Fi entertainment! The film has a good pace and there's the occasional suspenseful moment to enjoy. The monster-transformations and special effects are really tacky but what else did you expect considering the money that was involved? This charming little movie may not be very appealing to the younger generation of fans, but I warmly recommend it to admirers of classic science fiction. The rating here on IMDb is WAY too low!
