is a 1951 French-Italian comedy film directed by Luigi Zampa and starring Aldo Fabrizi, Sophie Desmarets and Peppino De Filippo.
For several years he has had two families, a wife and scrounging Neapolitan brother-in-law in Rome and an attractive widow with a young daughter in Paris whose existence he has managed to keep secret from the other.
When he is offered the chance to work permanently at one location he chooses Paris, but complications ensue when his brother-in-law follows him to the French capital.
Gian Piero Brunetta highlights, with regard to this period, the "progressive integration of writers in cinema", so in Signori, in carrozza!
Brunetta himself sees this commitment, however, simply as a "recruitment of intellectual workforce for the manufacture of products destined for popular markets".
