Yesterday (2019)

This is a great example of a story that has some very funny components to it but the overall plot requires an absolute suspension of belief.  It is a what if movie that is loads of fun to watch, but not too terribly deep when all is said and done.
So here is the story.  Jack won a talent show when he was 14 years old, and his friend Ellie encouraged him to make a career of it, which in his twenties he is in the midst of doing.  He has some moderate success but has decided it is time to call it quits, when there is a 12 second blackout world wide that leads to him having a bike accident.  He loses consciousness and two teeth and the world loses The Beatles and Coca-Cola.  It is a warp in the space-time continuum.
Tentatively at first and then in earnest he starts to recreate their songs, and as you would imagine, he becomes a world wide sensation over night.  He doesn't have a huge ego about it--he remembers where he is got the material, but he does start to lose his friendship with Ellie, who is obviously the love of his life.  It is a feel good movie filled with classic music.
