Species (1995)

A "friendly" galactic message containing a recipe on how to combine extraterrestrial DNA with human DNA is sent to scientists on Earth. The scientists, led by Fitch (Kingsley), whip up a batch of genetic material resulting in a sexy half alien, half human procreating/killing machine named Sil (model Henstridge's film debut). Naturally, Sil escapes from the lab, leaving the scientists with the unenviable task of catching her/it. All-star special effects team, including "Alien" designer H. R. Giger, create over-the-top, stomach-churning thrills. Dips liberally into the tricks of many sci-fi classics. For avid gore-meisters only.
