Italian directors Fabio Grassadonia and Antonio Piazza discuss their film "Iddu," which is in competition at the Venice Film Festival. The film tells the story of mafia boss Matteo Messina Denaro, who died in September 2023. He disappeared in the summer of 1993 and spent the next 30 years on the run as the Italian state cracked down on the Sicilian mob. The long flight of the head of the Sicilian mafia is "a black page in the history of Italy," says the Sicilian director Piazza in Venice. IMAGES AND SOUNDBITES
