A while back, I made a post detailing why I had decided I would not go to see the Red Dawn remake still in production, which was planned to use China as the villans, replacing the Soviets. In summary, though there were many reasons not to see the film, my main beef was that I would find it impossible to suspend disbelief, as the entire premise and the plot details that came from script leaks indicated that the plot required essentially giving the foreign policy makers of both the US and China a giant, flaming Idiot Ball.
Now, more recently, it seems that this premise that was terminally stupid to begin with just got that much more ridiculous (LA Times):
[T]he filmmakers now are digitally erasing Chinese flags and military symbols from "Red Dawn," substituting dialogue and altering the film to depict much of the invading force as being from North Korea, an isolated country where American media companies have no dollars at stake.
Yes, that is what is being reported. Apparently, distributors were worried about the effect of the film on the China market. Understandable from a business standpoint, if galling. Pleasing the censors in China is key to getting films into the China market, and if you support a film where not just some Chinese people but the People's Republic of China itself as the main villian, you might cause trouble for yourself. Not that the film has a chance to be approved even with North Korea as the villan, but the distributors were probably worried that it could cause fewer of their films from being approved, or -- worst case -- China reducing its quota of 20 foreign films a year in protest.
Why would North Korea invade? I have no idea. I'm not sure the filmmakers do either -- the fact that the film is simply being digitally altered and no mention is made of reshooting, I don't think they are giving much thought to the reasons for starting a war, much less have thought at all about how the North Korean military might behave differently from the Chinese military. They are faceless villians, pure and simple, there to invade, show themselved to be evil, and be heroically defeated. Not that faceless villans are always a bad thing, but when they come from the real world -- the modern world particularly -- I would wish for just a little more nuance.
