Facehugger, Xenomorph, Chestburster; the titular alien in “Alien” takes many forms, all of them terrifying, as the creation of gory special effects and a dark imagination. The crew of the spaceship Nostromo is hopelessly outmatched against this unique evil, though they never stop trying to kill it, even as more and more humans fall victim to the alien’s attacks. A straightforward human-versus-nature story, the movie manages to slip in a biting critique of mega-corporations which are more interested in the bottom line than human lives.
