District 9 rises above its disparate components—there are multiple strong influences, everything from Alien Nation to the faux-documentary feel of The Office—to deliver a socially resonant story that's even more relevant a decade after its release. Like all good science fiction, its impact derives from how it weaves in the trappings of everyday life, perhaps illuminating our own foibles.

Inspired by the 1962 Cinemascope epic The 300 Spartans that he saw as a lad, writer/artist Frank Miller would go on to create the five-issue graphic novel 300, a wildly stylized, heavily fictionalized account of the Battle of Thermopylae. In his telling, full of indelible images and gruesome violence, the historical events of brave King Leonidas and his 15-score soldiers' resistance against an innumerable horde are elevated to nigh-mythological status. Led by the self-proclaimed god-king Xerxes, Persia was mercilessly conquering much of the world, but the willful Spartans, still renowned as the greatest warriors ever, dared to stand their ground.

Star Wars imitators were both inevitable and plentiful in the late 1970s. The Buster Crabbe science fiction/adventure serials of old were a strong influence on that blockbuster, and whereas Buck Rogers was destined for a television reboot, mega-producer Dino De Laurentiis had already acquired the movie rights to Flash Gordon years prior. And so the space-faring hero returned to the big screen, reimagined in a lavish international production.

When we think shark, we think scares, but the incredible thrills that helped propel Jaws to the #1 box office crown in 1975 would not have been nearly as effective without a rock-solid story and engaging characters. (That's one explanation for the many awful rip-offs.) Peter Benchley's best-selling first novel gave director/ uncredited screenwriter Steven Spielberg tremendous fodder, with concrete plot points, clear motivations, and rich backstories.
