Trivia

Actress Moana Pozzi plays a foreign friend of Manuel Fantoni (Angelo Infanti) and is also the girl pictured on the poster hanging in the room of Sergio (Carlo Verdone) and Marcello (Christian De Sica). It was stated that the flat of Manuel Fantoni was owned by Pozzi, while Carlo Verdone stated that it belonged in fact to a friend of her. Verdone stated also that he decided to cast Pozzi just after having met her while visiting the apartment during the pre-production, while she was a guest by her friend.

First movie in which Carlo Verdone plays an only character.

The home of Nadia (Eleonora Giorgi) is located in Via Umberto Saba, but in the movie it's stated to be in Via Elio Lampridio Cerva, which in fact is not far from there and hosted other shootings of the movie.

The title is taken from a sentence told by Carlo Verdone to Eleonora Giorgi at the phone, defining the movie "as light as a cloud, like talcum powder". "Borotalco" is the Italian for talcum powder, but is in fact a trademark of cosmetics manufacturer Manetti & Roberts, who sent a cease to Carlo Verdone and producer Mario Cecchi Gori short before the movie release in order to change the title. But after having been positively impressed by the movie, the manufacturer decided to withdraw its request.

The surreal speech of Augusto (Mario Brega) to Sergio (Carlo Verdone) was inspired by a real argument between Brega and actor Gordon Scott while filming Buffalo Bill - L'eroe del Far West (1964).
