These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
In the Rifftrax for the original Red Dawn, the characters survey their wrecked town while the commentators say "They replaced our town with Detroit!" Guess where the 2012 remake was filmed?
Before it was pushed back, the remake was going to be a Dueling Movie with the film adaptation of Tomorrow, When the War Began, which is essentially Red DawnIN AUSTRALIA! Two of the Dawn remake's stars, Chris Hemsworth and Isabel Lucas, are Australian themselves.
One of the Wolverines, Daryl, makes a Call of Duty: Modern Warfare reference. Before the 2012 remake came out, there was a mission in Modern Warfare 2 that had a Red Dawn 1984 reference. The mission was called Wolverines! and the achievement for that mission was Red Dawn.
Also, apparently in this continuity Russian ultranationalists took over control of the country. This is exactly how Modern Warfare series begin.
