Lucio Fulci and Paolo Heusch were assistant directors. It was shown as part of a retrospective on Italian comedy at the 67th Venice International Film Festival.^[2] It took in around 473 million lire at the Italian box office.^[3] A young Lucio Fulci originated the idea and format for this film, and then helped to write the screenplay and assist Steno in directing it, making it the largest screen credit in his career up to this point.^[4] Critics said the film was carried by the versatile acting of Peppino De Filippo, who was convinced to become a comedian by the Italian actor Totò. Alberto Sordi's character of Nando Moriconi became so popular, he reprised the role in several later Italian comedies, such as An American in Rome (1954), without ever sharing the credit with Fulci. Fulci always took credit for creating the Nando Moriconi character, although Alberto Sordi said it was his portrayal of the character that made it so popular. Fulci said that in post production, producer Carlo Ponti almost cut the segment out for time constraints, but Ponti's wife Silvana Mangano made him leave it in. The film made a fortune as a result, according to Fulci, and helped launch Sordi's comedy career.^[5]
