Shot by Sofia’s mother Eleanor this documentary shows something of the strain of shooting a period piece, but is a far cry from the tumultuous portrait of her husband in Hearts of Darkness

It is 20 years since the release of Sofia Coppola’s Marie Antoinette starring Kirsten Dunst; it is a supportively unjudging, unironised study of the queen’s early years before the 1789 revolution, lavishly and accurately costumed, shot on location at Versailles and based on the Antonia Fraser biography – but also subversively and amusingly using pop tracks from the 70s and 80s on the soundtrack. It got a storm of booing from French critics, reportedly annoyed at the way their history had been reduced to a music video and fashion shoot with no French actors involved. Or hardly any.

In fact, for all the lack of political grit, the film was interesting and accomplished, and deservedly has a fanbase – and it is to that constituency that this making-of documentary from the director’s mother Eleanor Coppola is really addressed. It is basically a sweet family home movie on digital video which shows something of the strain and the longueurs of shooting a demanding period picture, but tactfully not seeing anything really explosive or bad-tempered. It is very far from Eleanor Coppola’s sensational behind-the-scenes film Hearts of Darkness: A Filmmaker’s Apocalypse about the tumultuous creation of Apocalypse Now, directed by her husband Francis Ford Coppola.
