An old prince (Eduardo De Filippo) lives in his ancient palace in Rome together with the ghosts of his ancestors; he proudly rejects a huge offer for the palace by a real estate group seeking a place to build a department store; but the prince suddenly dies (and joins the ghosts!) and his nephew (Marcello Mastroianni), just back from the States, sells the palace for a much lesser price. The old palace seems lost but here come the ghosts which manage to create a Caravaggio-like painting in the palace, which is so declared national monument and saved from destruction. A little satirical masterpiece about real estate speculation in 1950s Italy. And a great cast with the best Italian actors of the time: Eduardo, Buazzelli, Gassman and Mastroianni playing three characters.
