One of you mentionned the "7 company" which was one of the worse french movies of the 70's!
There is a few very good french movies about WWII, the two best are "un taxi pour Tobrouk" (A taxi for tobruk) and "la bataille du Rail" (The battle for the railway); I have also to mention "Paris brule t'il?" (Does Paris burn?) for the patriotic pride it gives me every time I see it. There is also a very good one about WWI: "la grande illusion" (the great illusion, french is preaty easy tongue isn't it?). I love, like most of you, "Kelly's heroes" (the great song and D. Sutherland as a tankleader is really tremendous!), "Das boot", "the big red 1", "the magnificent dozen" (which french title is stupid: it could be translated "the twelve bastards!") and "cross of iron". The first 30 minutes of private Ryan sound also very realistics. Talking about other movies about war I am very surprised that nobody mentioned "Jonnhy got is gun" which is for me the best movie about war I have ever seen!
And the last but not the least, maybe the main reason why I am now a MD: "M.A.S.H.".
