Earlier quoted context omitted.
Good luck finding a movie about Isaac Newton or Einstein, or literally anyone whose value to the world is more than pretending to be someone else or lying a lot, let alone a very interesting mathematician no one recognizes. (Ok I know there’s a few movies about folks like Turing and Nash, but it’s pretty slim pickings).
This whole theme is sort incompatible with movies. Most people like to relate to the characters in the plot. The "genius guy" does something we can't understand has very little appeal as a story. Same thing goes for mathematics that is too "deep". Most people could not care less about prime numbers. Yes, they drive important cryptographic procedures. But we care about cryptography. We care that the message gets to it…
I think the real issue is the producers and directors and business folks in the film industry are not in that camp. They’re more likely to make a biography of Robin Williams than Paul Dirac, and they decide what gets made.
