John Brannox has a quite interesting collection of 18th century Venice landscapes made by Canaletto and other painters of late baroque. You can see it in third episode, at the time of his rejection.
Even though it was released as a new series, it shares the same cast, crew, ... with The Young Pope, and plot-wise is like its second season, as it starts where the Young Pope ends at the end of the first season.
Both John Malklovich and Jude Law are linked to Patricia Highsmith's Ripley saga, having Malkovich performed the reckless man in "Ripley's Game" (2002) and Law his victim Dickie Greenleaf in "The Talented Mister Ripley" (1999)
In the final scene of the final episode you can see Pío, Esther's son, riding a tricycle just like Danny in The Shining (1980), a possible nod to Stephen King.
Soundtrack by American musical duo Sofi Tukker.
