Pietro, in order to satisfy the cravings for luxury and upper class respectability, of his beautiful wife, changes job from bathroom equipment salesman to arms salesman .....his earnings shoot up, but so does his problems !!!
He increasingly becomes out of touch of his family's obvious enjoyment of their prestigious social status, and selling weapons to petty African dictators(some very funny scenes) is stressful to say the least made worse by the presence of a rival French salesman!
It is a common theme in Alberto Sordi films of men victim to their beautiful wife's whims, to the extent that they sometimes ruin themselves !! Also this obsession of attaining high class 'respectability' is definitely an all Italian phenomena, esp. in the 1950's and 60's.
However Alberto Sordi always manages to make fun, of these national tracts without being overbearing and rhetorical.
The film in the second half , losses direction and becomes a boring,moral and anti-war rhetoric....a pity....with a bit more thought this part of the film could have been made better. But films in those times(1950's & 1960's), in Italy, at least, were quickly written and made on shoe string budgets, hence, the rather silly names to these films.Money had to be made quickly on these films, so little time on the artistic side was dedicated.
I have always felt that a remake could be made of the film,perhaps with Bob Hoskins or Danny de Vito in the role of Pietro. It's one of the few Italian films that could be successfully transposed to a more Anglo-Saxon settings.
It could a real hit !! My vote for the film a generous 7.
