I can't wait for the last hour where it just shows him showing up at meetings, saying Yes or NO and putting his names to games.
No, that'll be in the second act, when he becomes an alcoholic and starts using drugs, and everyone's like you're all washed up Miyamoto, it's time for you to give it up. Then, while he's contemplating suicide, he'll have this vision and return triumphantly to create The Legend of Mario: A Link to the Metroid's Past, a 90-hour sandbox RPG that ties the mythologies of every Nintendo franchise and Walt Disney into a a single, coherent storyline that even Professor Prole can't deny is the best story since the Renaissance. The novelization will win the Hugo, the Nebula, and the Pulitzer, and Miyamoto himself will direct the movie which will sweep the Academy Awards including Best Documentary. Then it will end with a compilation of clips similar to the end of Cinema Paradiso, except it will be hundreds of fanboys masturbating furiously.
