In this acclaimed sequel, the only survivor from the first film, Lt. Ripley (Sigourney Weaver), finds her horrific account of her crew's fate is met with skepticism -- until the disappearance of colonists on LV-426 prompts a team of high-tech Marines to investigate. Ripley travels with the team as an advisor, only to find that her biggest fear has come true. Weaver was Oscar nominated for Best Actress, while James Horner's chilling score also got a nod.
