Nick Vivarelli International Correspondent Italian twin directors Damiano and Fabio D’Innocenzo have started shooting in Rome on “Dostoevskij,” an eclectic detective drama involving a policeman with a troubled past. This first TV series written and directed by the D’Innocenzo brothers – who are known on the festival circuit for dark dramas “Boy’s Cry,” “Bad Tales” and “America Latina” – is an in-house Sky Studios production produced by the Comcast-owned pay-TV player with Rome’s Paco Cinematografica. Filippo Timi (“Vincere,” “The Eight Mountains”) stars as Enzo Vitello, a sharp detective with a troubled past, who winds up on the blood trail of a ruthless serial killer, nicknamed Dostoevskij because of letters full of gruesome details that he leaves at crime scenes.
