Species (1995)

"For three million years, the human race has been at the top of the evolutionary ladder. Nothing lasts forever."

Overview

In 1993, the Search for Extra Terrestrial Intelligence Project receives a transmission detailing an alien DNA structure, along with instructions on how to splice it with human DNA. The result is Sil, a sensual but deadly creature who can change from a beautiful woman to an armour-plated killing machine in the blink of an eye.
