I have seen this film (dubbed into Russian) back in USSR (before 1989). In soviet Union, dubbing of foreign films was an art form of the highest professional level. It is a great comedy in the ranks of "It's a mad, mad, mad world"(USA) and "Brilliantovaya ruka"(Diamond Arm) (USSR). Bourvil, Louis de Funes and Terry Thomas are the three pillars of European comedy cinema of the 1960's. Here, I finally found out the tile in English and French, because translating from Russian "The Great Promenade" only garnered me blank stares. It's a great example of how a free people love to make fun of their conquerors. Unfortunately war is not often as much fun as this film.
