Paul Mescal and Barry Keoghan will play Paul McCartney and Ringo Starr in the upcoming Beatles films - with a Stranger Things star also portraying one of the Fab Four.
The two Irish actors will be joined by London-born performers Harris Dickinson as John Lennon, and Joseph Quinn as George Harrison.
The cast for the Sam Mendes project was revealed at the CinemaCon event in Las Vegas, with all four appearing on stage and taking a bow together in Beatles style.
Mendes is making four interconnected films - one from the perspective of each of the band members - and they are all set to be released "in proximity" to each other in April 2028.
It marks the first time The Beatles and the families of John Lennon and George Harrison have granted full life story and music rights for a scripted film.
Playing McCartney is another big role for 29-year-old Mescal, who recently starred in the Gladiator sequel and was nominated for an Oscar in 2023 for Aftersun.
Barry Keoghan - who also got an Oscar nod for The Banshees of Inisherin - will portray the other surviving Beatles member, Ringo Starr.
Meanwhile, Stranger Things star Joseph Quinn, who appeared with long hair as Eddie Munson in the fourth series, takes up the role of George Harrison.
Harris Dickinson has the challenge of stepping into the shoes of perhaps the most famous Beatle, John Lennon.
The 28-year-old recently starred in erotic thriller Babygirl with Nicole Kidman and also appeared in satire Triangle of Sadness.
Mendes told the industry audience at CinemaCon there is "still plenty to explore" despite the Beatles' rise having being well chronicled.
