First question (easiest): "How would it look?" Well, I think personally it should be a series. A friend of mine named batsonjacksont (you all know him) created a Michael Jackson biopic concept. Basically, the seasons covered a decade, and everything that happened in the decade was covered. Here's the problem with that format: The Beatles were actually together for (including Hamburg years and pre-Beatlemania) 10 years, one single decade. So how would we split the seasons? I had an idea: a lot of stuff happened in one year for The Beatles meaning there was more stuff that would be covered in a few years/one season. Probably about the same amount of stuff which was fit into batsonjacksont's MJ biopic's seasons.

Then, there would be a little epilogue showing all of their solo careers at the end of the last season

Would the last season cover the final hours of John Lennon.

Any ideas for cast?

In my opinion, Simon Helberg could be a good Ringo Starr, even if he's American. Is he a little old?

Possibly Alex Lawther or Fionn Whitehead for Paul. Fionn O'Shea just looks like Ringo. Don't know about John or George.

I meant all british people should be played by british actors.

As for the rest of our cast.

Nicholas Hoult as Brian Epstein, Paul Bettany as George Martin (maybe)

Aaron Taylor Johnson as John, Alex Lawther or Fionn Whitehead as Paul, ????? as George and Fionn O'Shea as Ringo.
