Cesare Fantoni reprised the role of Don Ignazio one year later in Letto a tre piazze (1960). The movie is totally unrelated to this one, but is also directed by Steno and has Totò as main character.
There is a French cut of the movie, which is overall shorter and features more scenes with Louis de Funès and fewer with Aldo Fabrizi.
As already in Guardie e ladri (1951), Totò and Aldo Fabrizi play respectively the roles of an outlaw and an officer of the law.
During filming, Totò caught the Australian flu in the middle of an epidemic. Production had to stop for several days.
Some critics made some parallels between the couple Totò - Aldo Fabrizi with Stan Laurel and Oliver Hardy, basing on body size and acting. In fact, although the differences between the two couples are actually huge, Totò, as like Stan, is thin and has got a more energic acting style and his characters always drive Fabrizi crazy, who is portly and calmer like Ollie. The parallelism was inspired by this movie's scene set in the hospital, in which many critics found similarities with Laurel & Hardy's County Hospital (1932): in both cases the thinner character annoys the fatter one who has a broken leg.
