Where was ZeroZeroZero filmed? The series took 148 days to shoot, across three continents and five countries (Italy, Mexico, Morocco, the USA and Senegal) in more than 300 locations. Deadlinereports that the first weeks of shooting were in New Orleans, United States, before filming moved on to Mexico, Italy and Africa. Rather than shooting the whole series in one language, each local language is used: English, Spanish, Italian, French, Arabic and Wolof. Is it based on a true story? The specific characters and plot are fictional, but they are based on a huge amount of real-life research. The TV series is based on the internationally bestselling book ZeroZeroZero, written by Italian writer and essayist Roberto Saviano, where he explored the inner workings of the world of drugs and dirty money.
