Alien

In space no one can hear you scream...The terror begins when the crew of the Nostromo (Sigouorney Weaver, John Hurt, Ian Holm) investigates a transmission from a desolate planet and discovers a life form that is perfectly evolved to annihilate mankind. Four decades later, nothing has topped Ridley Scott’s explosive sci-fi showdown between one of cinema’s most celebrated heroines and the perfect killing machine.
