The only time I can think of where cinema  adequately captures the idea of “genius” is this scene in Amadeus. Antonio Salieri, a mediocrity, laboriously composes a very simple piece of music, thanks Jesus for the inspiration, then presents it to his patron, the Emperor of Austria. Mozart, a genius, transforms it into a genuine work of art in only a few minutes. How does he do it? Simple. He’s having fun trolling the pompous court composer. Mediocrity is work. Genius is play.
