Hmmm... a bit of a chicken egg thing, I guess? Do the movies impart a certain world view? Or are the movies made to appeal to those with a certain world view? Or is it all a self reinforcing feedback loop? "paranoid prone individuals see a movie designed to appeal to paranoid individuals, which reinforces their paranoia, which in turn leads to more movies with more paranoia appeal," and so on?
It's probably some of that, although I think such movies and other elements of popular culture promote a distinctly black-and-white, good guys vs. bad guys viewpoint. As a result, most people have a very oversimplified, one-dimensional view of geopolitics, where "enemies" are viewed as no different than the typical Western bad guy or comic book super-villain.
