In the science-fiction thriller
Species (1995), Natasha Hentsridge appeared as the beautiful but deadly Sil, a human-alien DNA combo. In this sequel, Hentsridge portrays Eve, a government experiment concocted to gain an understanding of how to combat future aliens, while
Michael Madsen and
Marg Helgenberger repeat their roles from the earlier film. When astronaut Patrick Ross (
Justin Lazard) returns from the first manned Mars expedition, he's infected with the same DNA that spawned Sil and Eve. Hailed as a hero, Ross is pressed into politics by his father (
James Cromwell), a senator. Any woman who beds the sexually active Ross is immediately impregnated, with embryos quickly developing and killing the mother. Ross hides the offspring on a family estate, as LA cops begin to detect a pattern in the female deaths. At the lab where scientists are monitoring Eve, Dr. Laura Baker (Helgenberger) realizes that Eve has a telepathic link with Ross, and that these two hybrids hope to couple. Press Lennox (Madsen) and Colonel Burgess (
George Dzundza) figure Eve can be used to lead them to Ross. Cleared as a murder suspect, Mars mission astronaut Dennis Gamble (
Mykelti Williamson), joins Lennox and Baker and gets in on the action as everyone involved closes in on Ross.
Richard Belzer does a cameo as the President of the U.S., while
Peter Boyle makes an uncredited appearance as a scientist. ~ Bhob Stewart, All Movie Guide
