“In space, no one can hear you scream.” Rarely has a movie poster tagline said so much in so few words. For over thirty years, audiences have been simultaneously captivated and appalled as the spaceship Nostromo is invaded and its crew stalked by a terrifying parasitic creature. From the gore of the infant alien bursting from Kane’s chest to the mounting claustrophobia as Ripley discovers the monster has followed her into the escape shuttle, Alien is a chilling masterpiece.
