Watch : Beatles Biopics: Four Films to Star Paul Mescal, Barry Keoghan, Harry Dickinson and Joseph QuinnBarry Keoghan is letting his hair be. The Saltburn star debuted a new look after growing out his brown locks in preparation for his role as The Beatles drummer Ringo Starr in an upcoming four-part biopic. That'll be Paul Mescal playing Paul McCartney, Joseph Quinn as George Harrison and Harris Dickinson stepping into the shoes of the late John Lennon. And for Barry, he hopes to "humanize" the iconic group in the musical epic by getting to know Ringo on a more personal level. "It was sort of just one of those moments where you’re just in awe and you’re just frozen."
