The book follows the story of two castrati who become successful opera singers in Venice and whose lives are intertwined.
The cast will also include Ciarán Hinds, George MacKay, Mark Strong, Hunter Schafer and Thandiwe Newton, according to US media including Deadline, which first reported the news. A spokesman for Ford has confirmed it to BBC News.
Adele, one of Britain’s most popular music stars, released her last album four years ago and has been largely out of the limelight since she ended a Las Vegas residency a year ago.
She said she was planning to take “a big break” after last year’s run of live shows, and wanted to “do other creative things just for a little while”.
Ford, meanwhile, has been one of the biggest names in fashion, but has also made two highly acclaimed and stylish films – A Single Man, starring Firth and Hoult, in 2009; and Nocturnal Animals, which earned him two Bafta nominations, in 2016.
He sold his self-titled fashion house to Estee Lauder for $2.8bn (£2.4bn) in 2022, before saying he would “say goodbye to fashion” and “spend the next 20 years of my life making films”.
“I loved making the two films that I made. That was the most fun I’ve ever had in my entire life,” he told GQ.
