Roger Corman, king of the cult classics produced and directed this cult classic, and even makes an uncredited appearance as a doctor in the film. Susan Cabot (Sorority Girl) plays Janice Starlin, whose cosmetic company has started to lose sales because its marketing relies on her own once-impressive but now aging beauty. The eccentric Dr. Eric Zinthrop (Michael Mark) develops an enzyme extract from royal wasp jelly, which rejuvenates Janice, with one tiny little side effect: It turns her into a monster! Written by frequent Corman collaborator Leo Gordon (The Terror, Tower of London), this chiller co-stars Anthony Eisley (The Naked Kiss) and Barboura Morris (A Bucket Of Blood).
