Evil Spawn (1987)

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.

Bobbie Breese plays fading movie queen Lynn Roman who is unhappy because younger actresses receive all interesting film roles.The assistant of deceased Dr.Zeitman offers her the potion which should stop the process of aging.It works perfectly until Ruth turns into hideous bug creature with an urge to kill..."Evil Spawn" is a cheesy creature feature flick with plenty of rubbery gore and gratuitous nudity.The main performance of Bobbie Bresse is actually quite decent and it's nice to see cameos of John Carradine and Forrest Ackerman.I haven't seen re-edited version of "Evil Spawn" called "The Alien Within".6 rubber creatures of 10.The scene of nude swimming in the pool is truly priceless.
