It's a Korean Movie. Tae Guk Gi. It's about the Korean War, and these 2 brothers that get drafted, and the older brother does all this heroic stuff to get his younger brother out of the fight, and tons of bad stuff happens. Lots of action, and it's pretty moving, it's also pretty sad. It's interesting, because the Korean War isnt a war many people know or care about, but there's more Korean War vets than WWII vets now, and kids could go actually appreciate Korean War vets and the hell they went through for a war that ultimately amounted to nothing.
Only problem is, it's subtitled, a dubbed version may exist, I think it does, but dubbed live action always looks funny, so you may wanna ask the kids what they wanna watch.
For a Vietnam movie, Platoon is good, but I like Hamburger Hill way better. Forest Gump, actually, is very good for the war parts, and the story before and after them, it actually is one of my favorite movies.
Band of Brothers is good, but you'd have to use a week or so of class time to show it all, I know because one of my teachers showed it. Kids liked it, though.
Still, I'd reccomend Tae Guk Gi, it's a war kids dont usually think much of, or anyone thinks much of. Eventually they'll get around to seeing a WWII movie, or playing a WWII video game or something, but they're much less likely to see anything about the Korean War.
