And while the sci part of the sci-fi equation may be questionable in Scott's 1982 original, the production design felt so right to audiences that it has overshadowed almost every future-set movie since. Even if – with only two years to go – our world looks nothing like Blade Runner's vision of 2019, Scott's vision remains the benchmark for The Future.

William Gibson invented the future. He also coined the term "cyberspace", which earned his place not just in literary and sci-fi but also nerd history. His world of elite hackers, shady super-corporations and unfathomable artificial intelligences inform almost all modern speculative fiction.

Gibson didn't invent Blade Runner. He was just breathing in the same post-industrial silicon fumes as its director Ridley Scott and futurologist production designer Syd Mead, who also shaped the look of Aliens and Tron. A heady mix that stapled Blade Runner to the pantheon of film and ensures we're discussing it today.
