Mendes confirmed the news of the film project on March 31, 2025, at CinemaCon, showing up towards the end of the Sony Pictures presentation to reveal further details. Calling The Beatles “the most significant band of all time,” one that “redefined the culture and stayed with you for a lifetime,” Mendes added that he had “been trying to do a film for years, but I finally gave up” because he felt the “story was too big for one film” and a TV series didn’t seem quite right.
