I remember an interview with Akiyuki Shinbou, years ago, where he was talking about his literary influences and namedropped a bunch of old Japanese classics like Natsume Souseki; and in another interview Haruki Murakami said that he never read Souseki and gave up as an adult because he found it too hard and not very interesting.
Truth of the matter is, a lot of geniuses got into anime back then because the industry was so small and unregulated, compared to the cinema industry where you needed money and connection to make what you wanted; and so they went on to make anime instead of live action because they had the freedom to who mostly whatever they wanted with their geniuses instead of making Samurai Action #345 for Toho
