Maradona was the world’s most celebrated football genius, so when he arrived in Europe’s most dysfunctional city on July 5, 1984 for a record-breaking fee, all hell broke loose. He performed miracles on the pitch, leading the team to their first ever national championship but the charismatic magic he blessed the field with quickly faded when he became a prisoner of the city.

Compiled from 500-hours of never-before-seen footage from the Golden Boy’s personal archive, the documentary will premier at the Cannes Film Festival before its release on June 14. This will be the third film from the Academy Award and BAFTA-winning team behind Senna and Amy.

Altitude Films have released a teaser trailer from the documentary in which Diego is seen making his way from outside the Napoli stadium into a raucous press room. While a club official pleads with the press to calm down, Maradona appears quite serene amidst the madness. When a group of fans chanting, “Diego! Diego!”, come into view through a skylight, the footballer smiles as he observes the chaos.
