That reminds me of a german movie, "Die Brücke" (eglish title: "The Bridge"). Still one of the best movies showing the insanity of war. It's about a group of unexperienced soldiers (actually teenagers) that are sent out to defend a bridge. That bridge is not even important, but they think it is and defend it with their lives.
It was filmed in 1949, only 4 years after the end of WWII, not far away from where I live.
:hatsoff: Jackson
I found it but it's not listed with Blockbuster. Seems it got a VG rating.
