I love Lily James - she is an excellent actor with this classically beautiful face.
The premise of the story is interesting enough. A man wakes up one day and everyone has forgotten who the beatles are - it's like they never existed. Google them and nothing comes up - well except for pictures of insects. No one knows what coke or cigarettes are.
This man is able to capitalise on this and pass off the Beatles songs as his own. It meanders along a bit and most of the time I was wondering how much longer till it ended.
