And there is a close connection between these two films that delve deep into the entrails of Martone’s native Naples.In his well-received “Nostalgia”, praised by Variety as Martone’s “most rewarding film in years,” ace actor Pierfrancesco Favino plays the middle-aged Felice Lasco, who returns to the bustling port city after having lived in Egypt for 40 years. Once back, he is caught up in memories of a distant life spent in his hometown, as his criminal youth slowly catches up with him.
