I have a feeling all you war movie buffs are going to jump on me with both feet for this, but on the other end of the realism scale, I've always sorta liked "Castle Keep." I strolled into the theater to see it in the early '70s (I forget the exact year), knowing nothing about it, expecting to see your standard war movie, and instead got the most incredible surreal painting of a war movie. I saw it only twice, and that many years ago, but I still remember many, many details, which for me is unusual. Forget the weird side-plot about Burt Lancaster and the Count's wife. The theme of war destroying beauty was really overwhelming.
