Species

Species is a 1995 American science fiction horror film directed by Roger Donaldson and written by Dennis Feldman. The film is the first installment of the Species franchise. It stars Ben Kingsley, Michael Madsen, Alfred Molina, Forest Whitaker, Marg Helgenberger and Natasha Henstridge in her film debut role. The film's plot concerns a motley crew of scientists and government agents who try to track down Sil (Henstridge), a seductive extraterrestrial-human hybrid, before she successfully mates with a human male.

The film was conceived by Feldman in 1987, and was originally pitched as a film treatment in the style of a police procedural, entitled The Message. When The Message failed to attract the studios, Feldman re-wrote it as a spec script, which ultimately led to the making of the film. The extraterrestrial aspect of Sil's character was created by H. R. Giger, who was also responsible for the beings from the Alien franchise. The effects combined practical models designed by Giger collaborator Steve Johnson and XFX, with computer-generated imagery done by Richard Edlund's Boss Film Studios. Giger felt that the film and the character were too similar to Alien, so he pushed for script changes.
