"Tae Guk Gi" (The Brotherhood of War)
I know that Thoma5 had made mention of this movie in a SPR thread a couple of months back. "Brotherhood" was released on DVD here in the states about a week and a half ago.
"Taegukgi" is the story of two brothers sent off to fight in the Korean War, Jin-Seok and Jin-Tae. Jin Tae becomes a decorated war hero, motivated to do his best for his country, as well as use his performances as a means to get his brother off of the warfield. The two are eventually seperated, and Jin-Tae believes his brother to be dead, and he ultimately sides with North Korea, after a string of personal tragedy befalls him, as well as enduring the mental corruption that comes with war. It encompasses the war at home, the wars within ones self, and the essence of the struggles of a country divided by politics.
The films end is worth the rental cost, and is the peak of the emotional mountain that these brothers embarked upon, putting all their differences aside. It's a beautiful film, and while it's more or less the Korean "Saving Private Ryan", there is a lot to set the two apart, considering the deeper personal connection I found in "Brotherhood".
