La Grande Illusion, de Jean Renoir

This is a wonderful movie - beautifully directed and acted, a strong story about war and changing times, solidarity and humanity in hard times. It's amazingly modern for the time when it was made (1937) - the use of different languages (something unthinkable in Hollywood until recently), the portrayal of Germans as men as humane as the French. All in all, a great French movie, on a par with others such as Jeux Interdits, Le Salaire de la Peur or Les Diaboliques.
