Red Dawn released in 2012 starring Chris Hemsworth, Josh Peck, Josh Hutcherson, Adrianne Palicki, Isabel Lucas, Jeffrey Dean Morgan is loosely based off the 1984 Red Dawn.
The writing was pretty lousy. The characters lacked any kind of development, except for the viewer knowing Chris Hemsworth served in the Marine corps, little else is know about the other characters.
In the original Red Dawn the commander of the invading force is seen writing to his family. In his letters he talks about how is growing tired of the war. In the remake there is no such character development with the commander of the invading force.
