Fan number one Valeria Kementari asked this:
"Are we going to see the White Council attacking Dol Guldor?"
Peter Jackson:
"I'm not going to say just what and when, but I will confirm that both the White Council and Dol Guldur will feature in the movies. And not just in one scene either. Just how to visualise it has been a challenge, but fortunately Alan Lee and John Howe went crazy with ideas, and it should look pretty cool."
"In fact to celebrate the start of these 20 questions, I'll show you an exclusive photo of the White Council planning the attack on Dol Guldur! Even if you don't want to be hit with spoilers, you should still take a look. For the first image of Gandalf, Elrond and Galadriel brandishing an array of fearsome Elvish weapons."
LEEE777 The Hobbit is released December of 2012 and 2013.
