I think the movie can be made through another person's perspective, making Satoshi a mysterious character. This is about the Bitcoin movie, how Bitcoin is created, and can be pictured out from known personalities perspective, like the pioneer developers that help out Satoshi in testing BTC, though there is a need to have a lead person here from the pioneer developers, I do not know who is the most fitted one to be the main character and see how Bitcoin promulgated through his angle of perspective.
So, I think the movie can be created perfectly even without exposing Satoshi's identity, after all it is all about the creation and propagation of Bitcoin, the purpose and the hiccups as Bitcoin adoption spreads.
Yes, this has been shown in many movies before where there is an interesting character whose activities are well revealed but he is always kept in the spotlight, if Satoshi Nakamoto is presented in a movie like this then it will be great and the interest in him will increase among the audience. If these topics are highlighted more in such movies like how Satoshi Nakamoto created Bitcoin at that time and from what idea he actually developed the idea of creating Bitcoin or what other developers did at that time then I think it will be more interesting.
It is relatively easy to know the history of Bitcoin since it came to the market until now, but if those unknown topics are brought to the fore through the movie then I think that topic will be more acceptable and better.
It always seems to me that Satoshi Nakamoto must have faced many challenges to create what is currently the most valuable digital currency in the world, and how he actually created this coin and brought it to the market, despite all the odds, should be the main context of the movie.
