They filmed this movie years ago. Budget issues at MGM and they had to go back and change everything from the original Chinese invaders to North Korean invaders to appease our Chinese over lords, means it is just now being released.
Needless to say I am still going to check it out. However, changing the invaders to Norks from the Chinese just ruins the "realisim" of it. Yeah I know its a movie but the original was a cold war era movie and in that time a Soviet invasion wasnt too far from reality and was always in the back of everyones mind. With our crushing debt owed to the Chinese and the Chinese will to become the lone super power, this movie could have been as powerful and dare I say motivating as the original.
The original was pro-gun, anti-communist, a direction FAR from typical Hollyweird, and apparently as we have recently learned, far from the typical voter. I hope todays version takes a step in the right direction as well.
