The filmmakers added topical references relevant to a 2006 audience. According to the "Los Angeles Times", "With a wealth of new, real-life parallels to draw from in the areas of government surveillance, torture, fear mongering and media manipulation, not to mention corporate corruption and religious hypocrisy, you can't really blame the filmmakers for having a field day referencing current events." There are also references to an avian flu pandemic, as well as pervasive use of biometric identification and signal-intelligence gathering and analysis by the regime.
