It is universally agreed that Jean Renoir was one of the greatest of all directors, and he was also one of the warmest and most entertaining. "Grand Illusion" and "Rules of the Game" are routinely included on lists of the greatest films, and deserve to be. But although "Rules" contains scenes of delightful humor, neither suggest the Renoir who made "Boulu Saved from Drowning" (1932), or "French Cancan" (1954), "French Cancan" a delicious musical comedy that deserves comparison with the golden age Hollywood musicals of the same period.
