Earlier this year, the big-deal British film director Sam Mendes announced an utterly bonkers plan. Mendes’ past works include American Beauty, Skyfall, and 1917, and he’s clearly earned a lot of faith from the film industry. He’s going to spend all that capital by building a Beatles cinematic universe. Mendes isn’t just making one Beatles biopic. He’s making four of them — one for each Beatle. A few months ago, there were reports that a quartet of hot young actors had signed on to play the Beatles. Today, there’s news of one change that makes the whole enterprise feel even bigger.
