The original title is taken from a gag of the De Rege brothers, a couple of Italian stage actors active between the 1920s and the 1940s. Most of the movie gags are indeed typical of the avanspettacolo, the theatrical genre of the De Rege brothers.
Many scenes were improvised, for example the one where Pasquale Baudaffi (Lino Banfi) meets in Rome a priest of his hometown who begins slapping him, as stated by same Lino Banfi in an interview. Banfi said that director Luciano Salce was so amused that he couldn't stop laughing and hold the camera in place.
Lino Banfi stated that nowadays the movie is often used in therapies for people suffering from Parkinson disease, in order to stimulate their facial muscles.
Final film of Dada Gallotti.
