Thank you, John, for posting all this!  How wonderful. 
I recently re-read the book while on vacation.  I liked even better the second time. 
It's such a first-person narrative, I wonder how it will translate to film.  Is there a voice-over? So much of the story takes place in Elio's mind. 
So, they "sort of" did the peach scene?  I can't imagine how that will go...
Sad that the film is not set at the sea, as the novel is. 
Later!
