Onegaishimasu. I always wished that "Autumn Lightning" would be made into a movie. I even tried my hand at writing a screenplay for it!
Wow, that would be wicked difficult. I'm not sure which would be harder, the historical parts (so much background there!) or the internal processes like in the passage I quoted. I'd love to see it, though. AL is one of my all-time fave books.
BTW, do you remember the passage that follows that one -- the one about why he didn't quit? That's another one worth hanging onto.
