Giulietta Masina, who played the lead role in the film was Fellini's wife in real life. Just like her character, her husband used to cheat on her with many women - including a long time affair with no other but Sandra Milo, who played in the same film.
In 1964, it was announced that Marcello Mastroianni and singer Anna Maria Alberghetti would be starring opposite Giulietta Masina. Neither appeared in the final film.
