‘The Beatles’ Movies Cast ‘Game of Thrones’ Star Harry Lloyd as Producer George Martin (EXCLUSIVE)

The Beatles have found their legendary producer.

Harry Lloyd, the British actor best known for playing Viserys Targaryen in the first season “Game of Thrones,” is set to portray George Martin in the upcoming four-part Beatles biopic by director Sam Mendes.

Lloyd joins Paul Mescal as Paul McCartney, Harrison Dickinson as John Lennon and Barry Keoghan as Ringo Starr and Joseph Quinn as George Harrison in Sony Pictures‘ “The Beatles — A Four-Film Cinematic Event,” due for release in 2028.

The casting is being revealed by Martin’s son, Giles Martin, in a pre-recorded interview going out on the Ryan Tubridy Show on Virgin Radio U.K later on Friday. “He’s really good. He’s very committed,” he said. Variety has since confirmed the casting with the production.

Martin — was passed away in 2016 — was commonly referred to as the “fifth Beatle” for his extensive involvement in each of the band’s original albums. He wrote most of the orchestral and string arrangements and also played piano or keyboards on a number of their tracks. Once described as “the world’s most famous record producer,” across a 60-year career Martin produced 30 number one hit singles in U.K. and 23 in the U.S., winning six Grammys.

Alongside “Game of Thrones,” Lloyd has appeared in major shows such as “Wolf Hall” and “Legion,” playing Charles Xavier. He is due to star in the upcoming sixth season of “Slow Horses.”

The much-discussed Beatles films are now in production and being directed back-to-back by Mendes, with a trio of award-winning writers — Jez Butterworth, Peter Straughan and Jack Thorne — having penned the scripts. Production is expected to carry on into late 2026, with Sony releasing all four movies simultaneously in April 2028.
