Alien
In space, no one can hear you scream.
The terror begins when the crew of the Nostromo investigates a transmission from desolate planet LV-426, and discovers a life form that is perfectly evolved to annihilate mankind. One by one, each crew member is slain until only Ripley (Sigourney Weaver) is left, leading to an explosive showdown between one of the most celebrated heroines in cinema history and the perfect killing machine.
