2001: A Space Odyssey (Kubrick, 1968), they weren't necessarily predicting deep exploration of the solar system and encounters with mysterious monoliths -- though I rather suspect they were hoping for at least the first -- but rather speculating on the origins of human nature and consciousness and their relationship to artificial intelligence. Similarly, the dystopian world of Blade Runner (Ridley Scott, 1982), populated by replicants and traversed by flying cars, is supposedly set in 2019 -- a year now close at hand -- but is also centrally concerned with the nature of humanity in a corporate capitalist society. What I'm getting at is that sometimes science fiction writers and filmmakers distance themselves as Lucas does from any notion that they're commenting on the "real world," but sometimes embrace a specific foreseeable date, with a view to making either a prediction of the way things will evolve or a comment on the problems of their own day.
This is why I find Alfonso Cuarón's Children of Men such a puzzling film. It gives us a dank dystopian London that resembles the dank dystopian Los Angeles of Blade Runner, and it sets it in a specific time, the year 2027, a world in which human beings stopped bearing children 18 years earlier: i.e., in the year 2009 -- only three years after the film was made. But unlike Blade Runner, it doesn't seem to be telling us anything specific about either a predicted future or the way we lived then. It's a very entertaining film, full of violent action and suspense, with some wizardly work by Oscar nominees cinematographer Emmanuel Lubezki and editors Cuarón and Alex Rodriguez. The way they handle the film's much-praised long-take sequences, aided by special effects to give the sense of complex action taking place in a single traveling shot, is exceptional -- anticipating Lubezki's work in making the entirety of Birdman (Alejandro González Iñárritu, 2014) seem to be a continuous take. There are also fine performances by Clive Owen, Julianne Moore, Chiwetel Ejiofor, Clare-Hope Ashitey, and the inevitably wonderful Michael Caine.
But what is at the core of the film? Why does the failure of humankind to reproduce precipitate the worldwide cataclysm that the movie presents us? We have fretted so long about overpopulation that it would seem a blessing to have at least a pause in it, in which the world's scientists might take time to resolve the problem, or at least to discover the reason for the widespread infertility. Instead, we have a story that's largely about the mistreatment of immigrants. Why would non-reproducing immigrants, in a world with a declining population and therefore less pressure on natural resources, be a problem? Is it possible that this film, based on but radically altered from a novel by P.D. James, is promoting the extreme "pro-life" view, not only anti-abortion but also anti-contraception? Or is it simply that a world without, as one character puts it, "a world without children's voices" is inevitably a terrible place? The film's failure to suggest a larger context for its action seems to me to cripple it.

By Charles Matthews"Dazzled by so many and such marvelous inventions, the people of Macondo ... became indignant over the living images that the prosperous merchant Bruno Crespi projected in the theater with the lion-head ticket windows, for a character who had died and was buried in one film and for whose misfortune tears had been shed would reappear alive and transformed into an Arab in the next one. The audience, who had paid two cents apiece to share the difficulties of the actors, would not tolerate that outlandish fraud and they broke up the seats. The mayor, at the urging of Bruno Crespi, explained in a proclamation that the cinema was a machine of illusions that did not merit the emotional outbursts of the audience. With that discouraging explanation many ... decided not to return to the movies, considering that they already had too many troubles of their own to weep over the acted-out misfortunes of imaginary beings."--Gabriel García Márquez, One Hundred Years of Solitude
