Paul Mescal is an Oscar-nominated actor for his performance in Aftersun, and he will soon play McCartney in Sam Mendes' Beatles biopics. While he is a movie star, Mescal gained fame for his theater work. He previously starred in productions of Angela's Ashes, The Red Shoes, The Great Gatsby, and A Portrait of the Artist as a Young Man.

At their presentation on the main stage at Caesar’s Palace, the studio confirmed and brought out the long-rumored leads for each film — Paul Mescal as McCartney, Joseph Quinn as Harrison, Barry Keoghan as Starr and Harris Dickinson as Lennon.

Each film will tell the band's story from a different member's perspective, director Sam Mendes told the crowd at CinemaCon 2025.
