Species is a science fiction horror film directed by Roger Donaldson. The movie blends elements of alien invasion, genetic experimentation, and horror, creating a suspenseful and thrilling narrative.

The story begins with a group of scientists who receive a transmission from an alien source, providing them with the DNA sequence for creating a new life form. The team, led by Dr. Xavier Fitch (played by Ben Kingsley), decides to combine this alien DNA with human DNA, resulting in the creation of a female hybrid named Sil (played by Natasha Henstridge).

As Sil rapidly grows into adulthood, she escapes the lab, driven by an instinctual need to mate and reproduce. However, her alien side makes her highly dangerous, capable of transforming into a deadly predator. A team of experts, including a government assassin (Michael Madsen), a biologist (Marg Helgenberger), an anthropologist (Alfred Molina), and an empath (Forest Whitaker), are assembled to track down and stop Sil before she can breed and potentially wipe out humanity.

Species is known for its mix of horror and science fiction, with intense chase scenes, shocking transformations, and a chilling portrayal of an alien creature that is both alluring and terrifying. The film explores themes of scientific hubris, the dangers of genetic experimentation, and the primal instincts that drive both humans and creatures. 

Natasha Henstridge’s performance as the lethal and seductive Sil became iconic, making Species a memorable entry in the 1990s sci-fi horror genre.
