In 1968 American writer Philip K. Dick published his science fiction novel, Do Androids Dream of Electric Sheep? It told of the moral crisis of Rick Deckard, a bounty hunter who stalked androids—robots visually identifical to people—in a fall-out clouded, dystopic, partially deserted San Francisco.
In 1982 the novel was brought to the screen as Blade Runner, with its location changed to Los Angeles.
