" ... on the set I talked a lot with Vittorio Storaro, my director of photography, about the two visual reference points of the film: Magritte and the naïve painters. For example, we shot the night scenes, as you remember, in a coloration that is quite unusual for the cinema, that is completely in azure. That is, they are nights in which you can see everything, […]. Also in Magritte’s work there is the same type of night “eclairage.” There’s a painting by Magritte, called “The Empire of Light,” in which you can see a rectangular, almost horizontal house, with a tree, and two lighted street lamps just like in the scene at the train station when Athos the son is getting ready to leave at the end of the film."
