Les vieux de la vieille

I saw this on French TV about a year ago - a great ensemble performance by 3 of the best (though aged) French actors hamming it up - kind of the outcasts of their little town due to general crochetiness (especially a destructive rampage by Gabin at a dance hall). The most memorable scene finds them lost in open country, where an unreadable signpost is discovered. Much arguing ensues. Much wine is also consumed on the way to their final rest...home.
