"At its most fundamental level, Alien is a movie about things that can jump out of the dark and kill you. It shares a kinship with the shark in "Jaws," Michael Myers in "Halloween," and assorted spiders, snakes, tarantulas and stalkers. Its most obvious influence is Howard Hawks' "The Thing" (1951), which was also about a team in an isolated outpost who discover a long-dormant alien, bring it inside, and are picked off one by one as it haunts the corridors. Look at that movie, and you see Alien in embryo. In another way, Ridley Scott's 1979 movie is a great original. It builds on the seminal opening shot of "Star Wars" (1977), with its vast ship in lonely interstellar space, and sidesteps Lucas' space opera to tell a story in the genre of traditional "hard" science fiction; with its tough-talking crew members and their mercenary motives, the story would have found a home in John W. Campbell's Astounding Science Fiction during its nuts-and-bolts period in the 1940s. Campbell loved stories in which engineers and scientists, not space jockeys and ray-gun blasters, dealt with outer space in logical ways."
