How about this?
This movie was filmed a while ago, how about ANOTHER "based on a true story" movie dramatization about a chess prodigy? I think MAGNUS CARLSEN would be a great choice. He was arguably an even better player than Josh. He beat or tied (forgot but either one is amazing) GARY KASPEROV at age 13. The kid in this movie could not have done that (at least not by age 13). As much of a genius as he was this was GARY KASPEROV one of the best players of all time. I think now as an adult he might have surpassed Kasperov or be very close to doing so.
He recently won the world championship against that Indian man without losing a single game, it was eleven game match and there were several ties but he won the rest.
A movie dramatization of that guy would REALLY be amazing. Being an even better player than Josh means he deserves a movie about his early life even more.
