According to Comic Book Movie on Sept. 1, a promotional image from "The Hobbit: The Desolation of Smaug" shows an image of the last shapeshifter of Middle-earth by the name of Beorn. This photo shows him in his bear form, but is also known to come to the aid of Gandalf and the rest of the party who had been retreating from Azog the defiler.
For those who have read "The Hobbit" book, fans may have conjured up images of his human form as being "au naturel". Typically his kind is prejudice towards dwarves, however, since both share the common foe of Azog, he had no qualms with coming to their aid in the literary work.
The image was derived from "The Hobbit: The Desolation Of Smaug Annual 2014" and shows an up close and personal mug shot of Beorn in a fierce state. This publication is a mixture of educated guesses, spoilers, and other plot details, so for those who would like to be surprised, feel free not to read the new publication.
After their arrival at Beorn's domicile, Gandalf speaks of the rumors may be happening in Dol Guldur and confirms his suspicions with the "woodly" shapshifter that what's occurring there is true about whatever evil lurks there. Thus Gandalf breaks away from the party as he usually does, leaving them to fend for themselves in Mirkwood.
They then encounter the leader of the wood elves, Thranduil, and are captured. The condition of their release from custody is dependent upon Thorin sharing a cut of the gold that dwells within Lonely Mountain.
Other content in the publication notes that the newly made character by Peter Jackson, Tauriel, who comes from the race of wood elves, is more of a dwarven sympathizer and doesn't share the idea of segregating the their races.
Spoilers continue to move forward in the new book and reveal furthermore other plot points and the like.
"The Hobbit: The Desolation of Smaug" will be released in theaters come Dec. 13.
