Alien

In space no one can hear you scream.

A commercial space freighter, the Nostromo, is diverted by a distress signal to an uncharted planetoid. The crew investigates, unaware they are about to encounter a lifeform of extraterrestrial origin—a creature of nightmarish design and lethal efficiency. Stranded in the darkened corridors of their ship, the crew must survive against an organism that hunts with precision and purpose. Ridley Scott's masterwork fuses science fiction with primal horror, transforming a isolated vessel into a claustrophobic tomb. Sigourney Weaver emerges as cinema's defining action-horror heroine.
