In an interview with the Hollywood Reporter, screenwriter Carls Ellsworth says the new Red Dawn will be an updated version, set in today's world. So, we're assuming that eliminates a contingency of Soviet and Cuban forces as the enemy. The producers have said they will update the threat to be more in keeping with a "post 9/11" mindset, which is just a nice way of saying all Middle Easterners and brown people in general.
There's the problem. Right now we're not in the heart of a massive arms race with another superpower, who at any moment could brazenly try to take over America despite the best efforts of Colorado's proudest high school football program. We know how the modern terrorist attacks. They're not the "paratrooping" type and they're not going knock over the government and set up re-education camps. So how in the hell is our band of teenagers hiding in the mountains going to make any sense?
And, uh, not to get all political here, but notice how all through Red Dawn the Commies refer to the kids as "insurgents?" Where else do you hear that term in the news these days? That's right, their movie is going to ask you to root for scrappy insurgents fighting with homemade weapons against an invading force, in a world where, in reality, we're the military superpower hunting down those kinds of people.
Okay, But Why ELSE Shouldn't They Remake It?
The original Red Dawn populated its cast with all the big teen celebrities of its day, which means there's at least a half chance we'll get a Red Dawn featuring some High School Musical bastards and at least two Jonas brothers.
