Hemsworth, who filmed the movie before his star-making turns in "Thor" and "The Avengers," plays a Marine who happens to visit his home town when a horde of invaders attack. After the adults fail to stand up to a fierce army of North Koreans, he retreats to the woods with a pre-"Hunger Games" Hutcherson, among others, to "create chaos" for America's enemies.
Filmed three years ago, "Red Dawn" underwent substantial revisions after MGM decided to change the film's enemy invaders from Chinese to North Korean, so as not to diminish potential box office returns in China and to stave off charges of xenophobia.
The Awl obtained a copy of the original script in 2010, calling it a "bald example of how one-dimensionally America generally, at all levels, thinks about China and Chinese people."
"We were initially very reluctant to make any changes," said one of the film's producers, Tripp Vinson, of the heavy re-editing in the LA Times.
"But after careful consideration we constructed a way to make a scarier, smarter and more dangerous 'Red Dawn' that we believe improves the movie."
Here's a look at the original version of "Red Dawn," which was released in 1984 and starred Patrick Swayze, Charlie Sheen and C. Thomas Howell, mid-western teens who fight off America's favorite villain of yore, the Soviet Union.
"Red Dawn" comes to a theater near you November 21.
