Red Dawn (2012)

Chris Hemsworth (Thor) leads a group of teens in guerilla warfare after North Korean soldiers invade modern-day America. Remake of John Milius' 1984 World War III movie. 

In Washington State, Americans awake to the sight of foreign paratroopers dropping from the sky - the U.S. has been invaded and their hometown is the initial target. The citizens find themselves prisoners and their town under enemy occupation. Determined to fight back, a group of young patriots seek refuge in the surrounding woods, training and reorganising themselves into a group of guerilla fighters. Taking inspiration from their high school mascot, they call themselves the Wolverines, banding together to liberate their town and take back their freedom.
