This film tells us the story of the Française des Jeux, from 1933 to nowadays. The director's idea was not to make it an historical epopée but a dialogue between the times, to create a contemporary film. He chooses to use an equivalent cinematography (lighting, image processing) on both periods to link the scenes as naturally as possible. Thus, it is the sets (reconstruction of the Paris of the 30s, the smoky and dark atmosphere of the streets, the vintage cars and buses, etc.), the casting and styling (100 figuring and as many old costumes) which mark the change of era. The visual process isn’t caricatural. The choice of transitions, their modernity, allows unexpected jumps in time while preserving the fluidity of the storytelling. The music, played by a philharmonic orchestra (49 musicians), totally participates in this temporal journey by balancing the historical side with the modernity of the images.
