Natasha Henstridge was in Species, where she plays a human-extraterrestrial hybrid, but did not find fame until the sequel.
In 1995, she came to prominence with her debut role in the science-fiction thriller Species, followed by Species II and Species III. 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. In 1998, she played Eve, a more ambiguous genetic duplicate of Sil, in Species II, which was a failure at the box office.
