Entente cordiale (1939) | worldscinema.org

IMDB:
The history of the Entente Cordiale in the big and small picture, from 1898, when a French officer occupied the village of Fashoda, Sudan to 8 April 1904, when a series or agreements marking the rapprochement between England and France were signed. To this turnaround in public opinion corresponds a parallel evolution in the intimate feelings of two families, one English and the other French which will result in the French heir marrying the English daughter.
—Guy Bellinger
