A Pizzeria in Ealing, London, is dedicated to this movie and also called L'oro Di Napoli.

Director Vittorio De Sica, who also plays the role of count Prospero, often used to pick up actors for his movies from the streets. He proposed the role of count Prospero to lawyer Alfredo Jelardi, whom he had seen in action in a court in Naples and who was well known in Naples. De Sica invited the lawyer in a hotel in Naples to discuss the proposal: Jelardi was really interested, despite never having performed in any kind of recitation, but at the end he decided to refuse the proposal because the role remembered him too much some aspects of his private life. Jelardi asked De Sica to personally play the role drawing inspiration from him.

The kid Gennarino is played by Pierino Bilancioni (wrongly listed ad Pierino Bilancione), at his only movie appearance. As an adult Bilancioni became a well known and appreciated ice cream maker and owned a succesful cafe in Posillipo (Naples). He received many awards for his activity, in particular for his hazelnut cream.

Totò wasn't much happy with the choice of putting his episode at first place in the movie, because in revue theatre usually the first episode is the one with the less important actors. He later agreed with the decision after a meeting with Vittorio De Sica.

Movie adaptation of a series of novels written by Giuseppe Marotta in 1947, who worked as screenwriter for the movie. Marotta was very happy with the work made by cast and crew, same were them with his collaboration. On the contrary, he was absolutely unhappy with the producers who made some deletions for foreign audience. In particular he didn't like the attitude of Dino De Laurentiis, who required several modifies to the episode Teresa. Also censorship asked to modify the episode's ending, and Vittorio De Sica accepted in order to make them remove the ban for people under 16 years of age, making Marotta feel disappointed.

The dramatic episode Il funeralino wasn't initially edited into the movie, added only in later editions. It's the only episode not based on a novel of the original book.

On the first day of shooting there were so many people attending that it was needed the intervention of the firemen.

Many cast and crew members, starting from director Vittorio De Sica, stated that filming of this movie was a particularly good time for them all.

The building where count Prospero (Vittorio De Sica) lives was used again in Napoli violenta (1976) as police station. It's located in Piazza del Gesù Nuovo, Naples.

The episode Il funeralino shares some setting locations with Il giudizio universale (1961).
