I do think the author's premise is a little shoddy though. Broad similarities between the state of the world in 2006 when the film was made and today aren't all that shocking. In 2006 the world was far along the path of globalization set forth through policies developed after the fall of the Berlin Wall and championed by essentially every US president and their allies since. The author does allude to this when he writes "In 2006, all of this seemed plausible enough, but perhaps a little strident, a little over-the-top." I agree that in 2006 most (myself included) probably didn't think that globalization would face the challenges that it does today as quickly and dramatically as it has over the last two years. That being said, that nationalistic and discriminatory behavior and actions can result from decades of globalization and tolerance seems more a reflection of a natural (if not unfortunate) pendulum swing between two approaches on opposite ends of the spectrum. Any particular power of foresight on the part of the screenwriters/filmmakers seems to me like a stretch, although the author seems to insinuate this to be the case.
Maybe I'm thinking too much...the movie is really awesome and I need to watch again.
