* ActorAllusion: Having ChrisHemsworth go to a [[Film/TheCabinInTheWoods a cabin in the woods]] is rather [[HilariousInHindsight amusing]].
* BannedInChina: The villain was changed from China to North Korea to avoid this.
* ExecutiveMeddling: For the remake, the enemies were changed from Chinese to [[http://www.latimes.com/entertainment/news/la-et-china-red-dawn-20110316,0,995726.story North Koreans]] in post production, mostly to help the film secure a distributor, as no other major studio wanted to touch a film about China invading America. This happened after production ended, so they had to digitally alter all Chinese symbols and dub all Chinese dialogue.
* FakeAmerican[=/=]FakeNationality: Ironically, the main hero is played by an Australian while the main villain is played by an American.
* HeyItsThatGuy: ChrisHemsworth a.k.a. {{Film/Thor}} is Jed Eckert. Since this movie was meant to be released in 2010, this might also count as RetroactiveRecognition.
** Josh Peck of ''DrakeAndJosh'' will play Matt.
** Captain Cho is [[Film/DieAnotherDay Colonel Moon.]]
** Colonel Tanner will be played by [[Film/{{Watchmen}} The Comedian]].
** Smith is [[Film/CaptainAmericaTheFirstAvenger Jim Morita]].
** Robert Morris is [[Film/TheHungerGames Peeta Mellark]].
** Erica Martin is [[Film/{{Transformers}} Alice the Pretender Decepticon]].
** Toni Walsh is [[Film/GIJoeRetaliation Lady Jaye]].
** Alternatively, John Winchester and Jessica Moore.
* PropRecycling: The props department seems to not have had any Soviet heavy weapons on hand, so the DPRK jeeps have M2's.
** The Jeeps themselves are in fact Humvees. The Korean People's Army also apparently has so few tanks that they are using [=M1A2=] Abrams to garrison the city.
* RealitySubtext: The current political climate necessitated the change of the antagonists in the remake from China to North Korea. The notion of using Chinese in the first place for the remake was due to the dissolution of the Soviet Union. Noting that China was once an ally of the U.S. also fits the affiliation of China toward the end of the ColdWar.
* TheShelfOfMovieLanguishment: Actually managed to make it all the way through the production phase, only to get sunk by MGM's financial insolvency. It was also delayed because the premise of China attacking America scared off all other major distributors, so MGM had to change the villain to North Korea in order to make it more attractive to film companies, and even then it took several months before it finally found a distributor willing to take a chance on the film. It probably helped that ChrisHemsworth and Josh Hutcherson had recently found fame for ''{{Film/Thor}}'' and ''Film/TheHungerGames'', respectively.
* WhatCouldHaveBeen: Early drafts of the script had the protagonists fighting [[PostNineElevenTerrorismMovie Middle Eastern terrorists]].
