The man who plays the piano during the Vittorio Basile's wedding sequence is Sergio Cometa, the taxi driver protagonist of the previous Rak's film L'arte della felicità (2013).
The folk story "Cinderella the cat" was one of a number of folk tales collected and published by G.B Basile (1566-1632). The collection was entitled "Lo cunto de li cunti", in English "The tale of tales". The 2015 film "The tale of tales" directed by Matteo Garrone is based on Basile's collection, too.
The plot is loosely based on a folk story collected/published by G.B. Basile (1566-1632). Mia's father's name is Vittorio Basile. His first name Vittorio may be after the actor-director Vittorio De Sica to whom he bears a physical resemblance.
