The Oscar winner will star in the six-hour limited series The Monster of Florence, which will chronicle the work of American fiction writer Douglas Preston and journalist Mario Spezi, who examined the police investigation into the deaths of 14 people between 1974 and 1985, and uncovered procedural mistakes. At one point, Spezi himself was considered a suspect in the slayings, which targeted young couples enjoying romantic outings in the countryside. The story will be adapted from Preston and Spezi's own 2006 book on the case, The Monster Of Florence: A True Story.
