Species II (also known as Species II: Offspring and Species II: Origins) is a 1998 American science fiction horror thriller film, sequel to the 1995 film Species. The film was directed by Peter Medak and starring Natasha Henstridge, Michael Madsen and Marg Helgenberger, all of whom reprise their roles from the first film. The plot has Patrick Ross, (Justin Lazard) the astronaut son of a senator (James Cromwell), being infected by an extraterrestrial virus during a mission to Mars and causing the deaths of many women upon his return. To stop him, the scientists who created the human-extraterrestrial hybrid Sil in the original Species try using a more docile clone of hers, Eve (Henstridge). The film was followed by Species III (2004).
