The Wasp Woman (1959)

Synopsis
This goofy but entertaining horror cheapie from producer-director Roger Corman and company involves the efforts of a questionable scientist working for cosmetics magnate Susan Cabot, who is developing a new rejuvenating beauty cream derived from an enzyme secreted by wasps, intended to make women look eternally youthful. A vain woman obsessed with restoring her lost beauty, Cabot insists on being the first test subject. The solution proves remarkably effective at first, transforming her into a sultry raven-haired vixen...until she begins to take on the predatory traits of a giant female wasp, setting out on a nocturnal killing spree. Originally double-billed with The Beast from Haunted Cave, this cheesy monster mash inspired the less-amusing Leech Woman and was later remade for 1980s audiences (i.e., with a higher sex-and-gore quotient) as Evil Spawn. ~ Cavett Binion, All Movie Guide
