As a previous review says, this blends (a little) fact and a lot of (unavoidable) fiction into what was a real encounter at Lennon's apartment in 1976.
The whole scenario, dialogue and banter just seems SO real - and the acting is amazing! You will truly think it's John and Paul!
Probably one for die-hard Beatles fans though, as I think you would need to know a lot of the details of their lives and careers - plus the state of their relationship at this time - to understand all that is going on. But if you do, this film is nothing short of a joy and prompts many 'what-ifs' in your mind.
I hope that their final physical meeting was as warm as this one eventually turns out to be. (Lennon's initial coldness and nerves is a gripping part of the film).
It seems that, even after this meeting, the two of them were still sometimes at loggerheads on the phone, although it sounds like their relationship did largely improve as the 70s went on.
Life is too short for 'fussing and fighting' and I guess they thought they would have several decades to reunite and do some work together....I think that if, after watching this, you decide to take a risk and try to patch things up with a friend or a family member (after all, tomorrow might be too late), then that will be another worthwhile outcome from a fantastic film.
