Crosmando: The only reason SW got fame is because it was the "first" to put sci-fi on the screen in color with advanced special effects (yes I'm aware others probably did sci-fi on the screen but nothing close to the budget of SW). If a sci-fi movie that was done competently was on the big screen before SW it would of got that fame too.
That doesn't seem quite right. From what I've seen and gathered, a lot of the movies coming out were all pretty much the same, after war propaganda, murder mysteries, private eye, war time stuff, etc etc.
I think the public were starving for something fresh and unrelated to a recent war that they'd gotten finished with, a change of tone for everyone with something more light hearted. So if everyone wasn't starving for something new rather than something sci-fi, almost anything could have caught on.
I think it was this
documentary i watched sometime last year, talks about the time period, the making of the movies, lots of behind the scenes stuff.
