Imagine a world without Coca-Cola, Harry Potter, cigarettes and the Beatles. That’s the premise of this movie. But, if you were the only person who could remember their songs, wouldn’t you want to share them with the world?
Post script: There is a sequence in this preview that did not end up in the finished movie; Jack sings “Something” to another guest on James Corden’s Late, Late Show. The final version has an imagined revelation of two of the original Beatles showing up instead. That turned out to be just one of Jack’s nightmares. But keep an eye out for a surprise!
