Actor Barry Keoghan has lost over a stone due to the intense year-long filming schedule for the upcoming Beatles biopic, where he transforms into legendary drummer Ringo Starr. Keoghan attributes his unintentional weight loss to his ADHD medication, which can also cause weight loss. The four-part Beatles biopic, entitled The Beatles: A Four-Film Cinematic Event, will explore the band's evolution from unknowns in Liverpool to global superstars. Keoghan also addressed rumors of cheating on ex-girlfriend Sabrina Carpenter, denying the claims and explaining his retreat from the spotlight. Carpenter and Keoghan's relationship ended in December 2024 after a year of dating, with rumors of infidelity surfacing later.
