Apropos of RJ's articles, I recall a comment by Alfred Hitchcock on his producer, David O. Selznick.
Selznick, the producer of "Gone with the Wind", was known for his lengthy and detailed memos to his directors and writers. In fact, his biography was entitled "Memo from David O. Selznick."
In an interview many years after working together, Hitchcock said that he once received a memo from David O. Selznick. Hitchcock said that he was still reading it.
