In terms of the film itself, there was nothing much very new about 'Star Wars.' 'Star Wars' was a trailblazer for the kind of monumentalist pastiche which has become standard in a homogeneous Hollywood blockbuster culture that, perhaps more than any other film, 'Star Wars' played a role in inventing.
Now that we are used to globalisation it's hard to imagine a time when the countries behind the iron curtain were largely obscured from the western gaze. The Soviet bloc was a genuine mystery. Such was the dehumanisation of the Soviets that Sting could wonder in song if 'the Russians love their children too.'
No ideology better understands the need for enemies than neoconservatism, and when the cold war dramatically and unexpectedly ended, the way was prepared for the 'Arab threat' to emerge. 'True Lies,' the 1994 James Cameron comedy thriller starring Arnold Schwarzenegger, duly served up the Arab villain Salim Abu Aziz.
The first 'Red Dawn' was made at a time when Hollywood didn't stint in its use of Russian stereotypes. Cold war capitalist ideology construed the Soviets as different for two reasons - not only did they belong to another political-economic system, they didn't seem to possess the same emotions that 'we' do.
While the emphasis on effects became a catastrophe for science fiction, it was a relief for the capitalist culture of which 'Star Wars' became a symbol. Late capitalism can't produce many new ideas any more, but it can reliably deliver technological upgrades. But 'Star Wars' didn't really belong to the science fiction genre any way.
