According to The Hollywood Reporter, during a conversation between Mescal's Gladiator II director Ridley Scott and director Christopher Nolan at the Directors Guild of America in Los Angeles Tuesday, Scott revealed that Mescal has been cast in Sam Mendes' upcoming films about The Beatles.
When talking about his next project, the movie The Dog Stars, Scott was asked if Mescal was going to be in the film. At first Scott said that he was, before suggesting Mescal's schedule may be an issue.
While Ridley didn't say who Mescal would be playing, The Hollywood Reporter notes that rumors have suggested he was the frontrunner to play Paul McCartney.
No official casting has been announced for the films, although Ringo recently let it slip in an Entertainment Tonight interview that Barry Keoghan had been cast to play him.
