Science Fiction, especially the popular, has always encapsulated contemporary political concerns. Unlike high-brow Science Fiction, such as Slaughterhouse-Five or 2001: A Space Odyssey or The Left Hand of Darkness, which remain largely rooted to major philosophical concerns, Popular Science Fiction has always limited itself to either popular paranoia or thinly veiled imperial capitalistic ambitions. Celebrating the Eurocentric idea of the ‘human’ within the context of a galactic theatre which is specifically designed to denigrate the non-human and the sub-human, these tales—more often found on the small screen—become parables of human supremacy. The antagonists are always imagined in a variety of forms recognisable in their unsubtle representation of political fears or of a very human need for sanctioned violence. Taking the cue from Umberto Eco, this chapter strives to look at certain film and television texts—such as Superman, Star Wars, Star Trek, Firefly, Starship Troopers, Dune and Invasion of the Body Snatchers—and assess how Science Fiction, via popular media, serves as a subliminal mode of ideological indoctrination.
