I am a Beatles fan, but I think if I weren't, I would become one because of this movie. I've been to see it twice, and I've offered to pay the ticket price for other people -- that's how much I loved this movie. I can't give it enough thumbs up!
The plot turns on the fact that there are many universes, and many of them are identical except for one difference; in this case, the Beatles are missing. Jack has a beautiful voice that does justice to all the Beatles' various styles, Ed Sheerin keeps popping up in unexpected places, and Jack's manager has a hilarious way of issuing criticisms. You won't be sorry if you miss this movie, because you won't know what you're missing, but you'll be incredibly happy if you do go to see it.
