Aliens is a 1986 science fiction/action film directed by James Cameron and starring Sigourney Weaver, Michael Biehn, Lance Henriksen, and Bill Paxton. A sequel to the 1979 film Alien, Aliens is set fifty-seven years after the first film and is regarded by many film critics as a benchmark for the action and science fiction genres. In Aliens, Weaver's character Ellen Ripley returns to the moon LV-426 where she first encountered the hostile Alien. This time she is accompanied by a unit of Colonial Marines.
Aliens' action/adventure tone was in stark contrast to the science fiction/horror motifs of the original Alien. Following the success of The Terminator (1984), which helped establish Cameron as a major action director, 20th Century Fox greenlit Aliens with a budget of approximately $18 million. It was filmed in England at Pinewood Studios, and at a decommissioned power plant.
Aliens earned $86 million in the United States box office during its 1986 theatrical release and $131 million internationally. The movie was nominated for seven Academy Awards, including a Best Actress nomination for Sigourney Weaver. It won in the categories of Sound Effects Editing and Visual Effects.
