I love the common American boogeyman known as "government". I like to imagine the president or any other of the fuckers in high positions going to the film studios and explaining to them what the government has chosen and what they're gonna show in the movie. Instead of their more common leisure time - coke, hookers and moralizing.

Some military movies are sponsored by the military (not the government), but as much as you'd like there to be some conspiracy, it's dead simple - the marketing guys decided it's a great opportunity to recruit people and the director got to make an expensive movie for cheap.
