After three years since production wrapped, the remake of "Red Dawn," the story of a teenage band of guerillas defending American soil, starring Chris Hemsworth and Josh Hutcherson, will finally see the light of day this coming Thanksgiving.

Yahoo! Movies debuted the first trailer for the film, so you can finally see what's in store when "Red Dawn" opens on November 21.

The Invasion Begins
For those of you unfamiliar with the 1984 original, the story revolves around a group of teens who hide out in the woods and stage a grassroots rebellion after Soviet forces invade the United States. The trailer for the remake shows part of the invasion, which gets a much more action-packed reimagining. One of the enemy airplanes gets shot down, its wreckage destroying the house next door.

Wolverines Assemble!
Once in the woods and without a roof over their heads, Jed, played in the original by Patrick Swayze and in the new version by Chris Hemsworth, makes a call to arms, and the group forms a band of guerillas called the Wolverines. In the film, Hemsworth is joined by Josh Peck (who plays his brother, Matt) Adrianne Palicki, Isabel Lucas and Josh Hutcherson, who should know a thing or two about survival in the wilderness between "Red Dawn" and "The Hunger Games."

The Weapon
One of the biggest changes to the original film's story comes in the form of a weapon used by the invading North Korean forces. This weapon allowed the enemy to take over. Another significant change involves Jed and Matt's father, played by Brett Cullen of "The Dark Knight Rises." From the looks of the trailer, he dies considerably earlier in the remake.

North Korea
One change in particular grabbed headlines since "Red Dawn" wrapped nearly three years ago. In the original cut of the film, China invaded the United States. When filmmakers feared that casting the Chinese as the central villains of the film would compromise international ticket sales, the invaders became North Korean, thanks to a few post-production changes. In the trailer, North Korean banners fly as Peck runs through a city center.

Surprise Attack
One thing that hasn't changed in the new version of "Red Dawn" is the style with which the Wolverines attack the invading forces. The trap set by them at the end of the trailer closely resembles a similar plan hatched by the kids in the original.
