Nope, it's not any of those films. Only La grande illusion
is about the French, anyways, and I don't think it's that one. There aren't very many films about the French in World War I. Paths of Glory
is one (as noted by Lightwizard
), but that doesn't have a scene like the one Polarbear
describes. Un long dimanche de fiançailles
, with Audrey Tautou, is another, but that ain't it either. It might be Joyeux Noël
, which is about the Christmas truce in 1914 -- I haven't seen that movie.
It sounds almost like a scene out of Henri Barbusse's La feu
(English title: Under Fire
), but I don't know if there has ever been a movie adaptation of that book.
There are 909 titles under the keyword "WWI"
in the Internet Movie Database. Maybe one of those titles will spark a recollection, Polarbear
