Saoirse Ronan has been confirmed to play Linda McCartney opposite the previously announced Paul Mescal as Paul McCartney in director Sam Mendes's The Beatles - A Four-Film Cinematic Event.
US entertainment trade publication Deadline, which first reported Ronan's casting, says film studio Sony has also closed deals with Mia McKenna-Bruce (How to Have Sex), Anna Sawai (Shōgun), and Aimee Lou Wood (The White Lotus) to portray Ringo Starr's first wife, Maureen (née Cox) Starkey, John Lennon's second wife, Yoko Ono, and George Harrison's first wife, Pattie Boyd, respectively.
"Maureen, Linda, Yoko, and Pattie are four fascinating and unique figures in their own right," said director Mendes. "And I'm thrilled that we've managed to persuade four of the most talented women working in film today to join this amazing adventure."
Each film will focus on a different member of The Beatles.
Along with Mescal portraying McCartney, the films will also see Mescal's fellow Irish actor Barry Keoghan playing Ringo Starr, Babygirl's Harris Dickinson as John Lennon, and Mescal's Gladiator II co-star Joseph Quinn as George Harrison.

Ronan and Mescal previously starred together in the 2023 sci-fi thriller Foe.
Linda McCartney (née Eastman) was a photographer, musician, and animal rights activist. She married Paul McCartney in 1969 and was his bandmate in his post-Beatles outfit Wings. She died from cancer in 1998.
The ambitious four-film project marks the first time The Beatles, their multimedia company Apple Corps Ltd, and the families of the late John Lennon and George Harrison have granted full life story and music rights for a scripted film.
Speaking at the CinemaCon convention in Las Vegas in April, which the four male leads also attended, director Mendes called the films the "first binge-able theatrical experience".
"I've been trying to make a story about The Beatles for years," he added.
