Domenico arranges an apartment in Naples for Filumena. The former tenant's belongings are still in. There is a picture of Clara Petacci (dictator Mussolini's mistress) on the wall and Filumena asks when this will be removed. The scene is set in the late 1940s, so this obviously symbolizes Italy's transition from fascism to a republic. Mussolini himself would probably not have passed the censors.
In the movie the house of Filumena and Domenico is located in "Piazza del Gesù", a well-known square in the historic center of Naples. The scene where Filumena leaves the lawyer's office was filmed in "Piazza Bellini."
