This latest film about the graffiti artist who has become a global household name without ever revealing his identity, begins with the now-notorious Sotheby’s auction in which Banksy’s most iconic work, Girl with a Balloon, was instantly shredded by a mechanism in its frame just seconds after the auction hammer fell. From that art-historic moment, the film returns to the beginning of the Banksy narrative which has engaged the world and made him perhaps the most widely recognized name in art history. Providing an account of the artist’s rise to fame, while documenting the various forensic investigations that have attempted to solve the mystery of Banksy’s true identity, the film is at its most engaging when interviewing ordinary people about what his anarchic work means to them.
