Jean Renoir wrote about his link with the Popular Front movement, during the production of this film (1936-1938): "Il fut un moment où les Français crurent vraiment qu'ils allaient s'aimer les uns les autres. On se sentait porté par une vague de générosité." (Ma Vie et Mes Films, Flammarion, 1975) [For some time the French people did believe that they would love each other. One felt transported by a wave of generosity.]
