Well I love war movies and all those mentioned are good Stalingrad is a good movie only watched it once tho its just sat in my collection. One that I havn't seen or dont think I have Cellarat I couldn't be bothered to look through the mass you wrote. I think Shooter is a cracking movie.
I also Loved the Sniper Movies. The first one is definatly the best.
One film out this year that looks funny is this
