Nick Vivarelli International Correspondent Twin directors Damiano and Fabio D’Innocenzo, who are known to Berlin Film Festival audiences for stylishly gritty dramas “Boys Cry” and “Bad Tales,” are back with eclectic detective series “Dostoevskij,” premiering in the fest’s Berlinale Special section. Set in the stark Roman hinterland, the six-episode show — produced by Sky Studios with Rome’s Paco Cinematografica — stars Filippo Timi (“Vincere,” “The Eight Mountains”) as Enzo Vitello, a policeman whose mind is warped by an incident involving his daughter Ambra.
