The scene of "La sognatrice", where the sleeping girl has the cat on her abdomen and there is a horse poster on the wall, was composed in order to evoke the painting "The Nightmare" by Füssli.
When the kid ("Il bambino") turns to the window, he starts drawing "The Starry Night" by Van Gogh.
For the main characters, "Lui e Lei" (He and She), the directors were inspired by "Les Amoureux" by Raymond Peynet.
