Diego Maradona (2019, Asif Kapadia)

Asif Kapadia's Diego Maradona documentary uses 500 hours of previously unseen personal footage to construct the most intimate portrait of a genius and its self-destruction in football documentary history. Kapadia (director of Amy and Senna) frames Maradona's Napoli years (1984–91) as a Shakespearean tragedy — the golden god who became addicted to cocaine and the attention of the Camorra. The film won the BAFTA for Best Documentary in 2020. Its editing — particularly the sequence contrasting his 1986 World Cup heroics with his growing addiction — is considered some of the finest documentary filmmaking of the decade.
