Kendalf: "I'm inclined to go the other way, actually, and suspect Jackson will put off the slaying of Smaug as long as possible..."
In that case I wonder if the liklihood that Elves will be in Laketown in force, with Tauriel leading the pursuit of the Dwarves, when Smaug arrives there and then setting off immediately to Erebor following his demise.
I wonder what the link will be to get the goblins involved in the battle. Makes me wonder if the battle will be set up as the accidental meeting of 5 armies as in the book or if it will seem more planned.
Julia - yes, the book is well paced for a reader. That doesn't always tend to work on film and we already know that there will be some significant differences already. Just trying to suggest how it could be done given the format and story will be different.
