Ooh, I love foreign films! Here's my list of good French/francophone films.
~Jesus de Montreal (From Quebec, rather controversial regarding religion, but very very good).
~La Reine Margot (French, a historical drama)
~Bleu (French, part of a three film series of vignettes "Rouge, Blanc et Bleu)
~Au Revoir les Enfants (French, a war-time tear-jerker)
~Asterix et Obelix contre Cesar (It's really hilarious if you can find it - with Gerard Depardieu as Obelix)
