Peter Jackson Teases Smaug, the Necromancer, and Spiders in The Hobbit
First off, Smaug will appear in the prologue to The Hobbit: An Unexpected Journey--I'd imagine in the same vein we saw Sauron in the prologue to The Fellowship of the Ring. Additionally, Jackson said "remain as liquid tongued as the book's memorable villain (he is a character not a monster)."
Secondly, the Mirkwood spider scenes have been moved to next year's film, and that the arachnids will have "psychic communication" of a sort.
What do you think of the changes to the film... particularly the completely fully Jackson-created attack on Dol Guldur?
