A scene from Broken English.

VENICE 鈥 The life and career of British singer-songwriter are reappraised at the Venice Film Festival in Broken English, a movie that mixes documentary and fiction in an effort to redress her often distorted public image.

鈥淢arianne was an artist鈥檚 artist… but public perception had been frozen and been stuck. And I think that were it left to AI (artificial intelligence), broken data is just going to stay broken,鈥 said Jane Pollard who co-directed with fellow British filmmaker Iain Forsyth.

Often remembered as simply the former girlfriend of Mick Jagger, despite having released over 30 albums in her own right, Ms. Faithfull is portrayed through a series of interviews conducted in the years leading up to her death at 78 last January.

鈥淲hen Marianne died so many of the obituaries that ran were headlined 鈥楳ick Jagger鈥檚 ex-girlfriend dies鈥 … And you kind of think, would you want to be defined for a lifetime by a fairly fleeting relationship that you had in your youth?鈥 Mr. Forsyth told Reuters.

Placed within the setting of the fictional Ministry of Not Forgetting, the film also makes heavy use of archive material, including interviews with journalists who home in on Ms. Faithfull鈥檚 rock-and-roll escapades and drug addiction in London鈥檚 swinging 鈥60s rather than her creative work.

鈥淲hy have a Ministry of Not Forgetting? Well, because there are many artists whose legacies if left to the algorithms of AI will be misrepresentative of the truth,鈥 said Ms. Pollard ahead of the film鈥檚 premiere on Saturday.

鈥淚 hope (our film) can begin a conversation and begin a process of reevaluation, both of Marianne as an artist, but also how we consider particularly female artists in the media, which in 50 years has really not changed that much.鈥 Mr. Forsyth added.

Named after Ms. Faithfull鈥檚 comeback album released in 1979 after spending two years living on the streets of London, Broken English features actors Tilda Swinton as the ministry overseer and George MacKay in the role of record keeper and interviewer.

Ms. Faithfull, who suffered a severe bout of COVID-19 in her latter years, gives her final musical performance in the film, singing 鈥淢isunderstanding鈥 from her 2018 album Negative Capability with backing from Nick Cave and Warren Ellis.

鈥淭he physical feat of it with COVID having ravaged her body and not feeling comfortable to talk for long without oxygen, to take it away and to sing was incredibly moving,鈥 Mr. MacKay said.

Ms. Faithfull died during the production but the directors said the finished work reflected 99% of their intended vision.

Broken English is playing out of competition at Venice, meaning it is not in the running for the prestigious Golden Lion award that will be handed out on Sept. 6. 鈥 Reuters
