Nick Vivarelli International Correspondent France’s Les Films du Losange is taking international sales outside Italy on “Sicilian Letters” (“Iddu”), the hotly anticipated drama about Cosa Nostra boss Matteo Messina Denaro – who was dubbed “the last godfather” – directed by Fabio Grassadonia and Antonio Piazza (“Sicilian Ghost Story”). “Sicilian Letters” pairs two top Italian actors — Elio Germano, who plays Messina (see first-look image above) and Toni Servillo (first-look image below) as his antagonist Catello, a shady secret services operative — working in tandem for the first time.
