Joyeux Noël (2006)

With the advent of World War I, Europe is thrown into a brutal and vicious chaos as men are forced to kill or be killed. While blood soaks the battlefield as Christmas approaches, the men in the trenches of the Western Front face a transformation, however fleeting, toward peace and goodwill. Against all odds, four unlikely individuals from opposing sides (Diane Kruger, Benno Fürmann, Guillaume Canet, Gary Lewis) bond during this bloodless respite to experience the hope and goodness in humanity.
