One other film I’d also include in the “dark satire as prophecy” category is the now largely-forgotten 1979 comedy, Americathon.
Americathon predicted, amongst other things, the fall of the USSR, mainland China embracing capitalism and becoming a global economic superpower, Nike becoming a massive multinational conglomerate (Nike’s ‘Tailwind’ running shoe was just starting to gain popularity back in ‘79) and the widespread prevalence of reality television.
One of those flicks where you’re kind of left wondering if the screenwriters had access to a time machine, LOL.
