Microbes are brought back to earth via a space probe from Venus. A scientist is using them in experiments on aging, but dies before the work is finished. His assistant approaches an aging actress who is being passed by for the lead roles, and she injects the serum hoping to become young again. When the actress is still passed up for the plum roles, the alien bacterium transforms her into a hideous bug-like alien resulting in a predictable attrition problem amongst her detractors.
Practical Effects
The bug costume is genuinely grotesque — someone's cousin worked hard on this.
Acting
Bobbie Bresee commits to every shriek and transformation with B-movie dedication.

Director
Fred Olen Ray
Trivia, insights & behind the scenes
Fred Olen Ray shot his scenes in three days and reportedly never met co-director Kenneth J. Hall until years later.
This is peak 1980s direct-to-video horror, when any actor with a SAG card and a rubber monster suit could get distribution.
