The quiz show featured in this movie is Lascia o raddoppia?, aired on Italian state-owned broadcaster RAI between 1955 and 1959. It was the Italian version of the French quiz show Quitte ou double?, in turn based on the US show The $64,000 question (CBS, 1955-1958). It was the first quiz show on Italian television and an instant success. It was presented by US born Mike Bongiorno (the king of Italian quiz shows from the 1950s to late 2000s), assisted by Edy Campagnoli. Both Bongiorno and Campagnoli starred in this movie, although the studio of the show was recreated at the Cinecittà studios in Rome, while the real show was produced in Milan. RAI briefly remade the show several times: in 1979 with Mike Bongiorno and Edy Campagnoli's daughter Patricia Buffon; in 1989 with Bruno Gambarotta, Lando Buzzanca and Johara (as direct competitor of Mike Bongiorno's Telemike, aired on private channel Canale 5); in 1990 with Bruno Gambarotta and Giancarlo Magalli.
Carlo Croccolo (Camillo) stated in an interview that the scene where Duke Gagliardo della Forcoletta (Totò) trains for the quiz show in his wardrobe had to be remade several times because of Croccolo continuously laughing due to the scene being very hilarious. Both Totò and the director were really annoyed by this.
Production company Titanus sued Mike Bongiorno for having left the movie set when he had to reshoot a scene, in order to take part to a rally race. Titanus asked a refund because his absence would have caused a delay to the movie presentation. Bongiorno replied that the producers already had agreed with him his partecipation to the rally, adding that he was available to reshoot the missing scene. After that, the company decided to drop the lawsuit.
Carlo Croccolo (Camillo) stated in an interview that the first scene of his character was initially shot differently: Duke Gagliardo della Forcoletta (Totò) wakes up, goes to the drawers chest and opens a drawer where Camillo is sleeping in. The scene was filmed but never edited into the final movie. Croccolo told also that before filming this scene, Totò organized to make him a joke: he told the crew to call him for making him try if he could comfortably get into the drawer. As he got into the drawer, they locked him in and went to lunch. Anyway, they let him free after 10 minutes.
