In a statement, the 86-year-old director of the critical and box-office flop said the book confirms his feeling that ‘art can never be constrained’

Megalopolis, Francis Ford Coppola’s $120m passion project, was neither a box office nor a critical success on release last year. Largely funded by the sale of Coppola’s own vineyards, the sci-fi epic starring Adam Driver took around $14m at the global box office amid unconvinced reviews and rumours of abnormal on-set behaviour by its director.

A marketing campaign attempted to leverage bad critical notices by flagging that previous works by Coppola now acclaimed as masterpieces – including Apocalypse Now and The Godfather – had been dismissed by critics at the time. But this backfired after it emerged all of the sniffy historical reviews had been fabricated.
