Brian Epstein Issue
This is one of my favorite films of all time. It's nearly flawless except:
The depiction of Brian Epstein in one short scene was simply way off the mark. Being a life-long Beatles fan, I'm very familiar with how Epstein looked and acted. The actor they found to play him looked and acted like some slick Hollywood executive -- nothing like the real Brian Epstein. They could have easily found an actor who could have done a much better job portraying him.
But this is a very minor quibble. The scene in question lasts perhaps less than two minutes. I only bring it up because, as I say, as a fan of the Beatles, it was something that stood out for me. Not a big deal.
If you haven't already, do see this film. It's a top notch biopic.
