I don't resent James Ivory this win, at all. However, why was the author of the book Call Me By Your Name at the ceremony and Greg Sestero wasn't? ALL of the authors should have received an invitation. This category (and these great movies) wouldn't even exist without the source material. Supposedly, Sestero was reduced to scrambling around until the last minute trying to get an invite, which is a disgrace. If a book was worthy enough to be adapted into an Oscar-nominated film, the authors of all said books should be invited to the ceremony.
