Harry Potter author JK Rowling has updated the rumors section on her site answering questions about Dumbledore and Ron, Nicolas Flamel and the Creevey brothers. She also answers some fans letters in reference to chapter titles from Harry Potter and the Half-Blood Prince.
Rumor: There will be a chapter in Half-Blood Prince called Lupin's Papers
I’ve already answered this in FAQs, but as this rumour is still cropping up in fan letters I thought I’d reiterate here that there will be NO chapter called Lupin's Papers in book six, nor will there be chapters entitled Pettigrew's Pamphlets, Sirius's Circulars or the Pocket Crosswords of Severus Snape.
Let me remind you once again that any information about the contents of Half-Blood Prince should be treated with extreme scepticism unless it comes from this website or from my publishers or agent. The silly season is upon us; there’s bound to be an inside leak, ie, total fabrication, any time now.
Thanks to Paul for the update.
Rowling has also updated the FAQ section on the books including:
How did you feel about the POA filmmakers leaving the Marauder's Map's background out of the story?
I was fine with it. It is simply impossible to incorporate every one of my storylines into a film that has to be kept under four hours long. Obviously films have restrictions novels do not have, constraints of time and budget; I can create dazzling effects relying on nothing but the interaction of my own and my readers' imaginations - hence my preference for the page over the screen.
