Alien (1979) is the first film in what has become one of the most popular sagas in science fiction history. It introduces Ripley, the iron-willed woman destined to battle the galaxy’s ultimate creature. The terror begins when the crew of the commercial space-tug Nostromo investigate a distress signal transmitted from a desolate planet and discover a life form that is perfectly evolved to annihilate mankind. They encounter a pulsating organism that attaches itself to one of the crew members and reproduces within his body to become a deadly alien. One by one, each crew member is slain until only Ripley is left, leading to a final confrontation and explosive conclusion that sets the state for the stunning sequel Aliens.
