The two girls being with Emanuele Sansoni (Johnny Dorelli) on the yacht became famous in two distinct careers starting from late 1980s, so only after their performances in this movie: the blonde Moana Pozzi became a pornographic actress, while Louise Tracy Freeman became a singer under the name Tracy Spencer. At time of filming, Pozzi was known as character actress and TV host, while her pornographic career had already begun under a fake name, before her official debut in 1987. On the other side, this movie is Freeman's first movie appearance, followed by only other two ones also in 1984 (L'allenatore nel pallone and Domani mi sposo), after them she focused only on her singing career.
Many scenes were filmed in and near Rome, despite not being a setting of the plot. Scenes set in Rapallo were actually filmed in San Remo. French and Swiss locations are genuine.
The taxi cab of Gino Sciaccaluga (Paolo Villaggio) is a then brand new Renault 11. At time of filming, Johnny Dorelli (Emanuele Sansoni) starred in a series of TV commercials for Renault, including one for same Renault 11 in 1985, one year after the movie's release.
The shy and clumsy personality of Gino Sciaccaluga (Paolo Villaggio) has got many common points with the ones of Villaggio's usual characters Giandomenico Fracchia and Ugo Fantozzi.
In the first scene, a large poster of football club Sampdoria is shown, of which Gino Sciaccaluga (Paolo Villaggio) is a huge fan. Paolo Villaggio was a Sampdoria fan in real life too.
