Jackson spoke about what fans can expect from the final in the epic trilogy and gave away some decent spoilers. Reuters was reporting from the event and revealed the important bits. Jackson stated that some of the main characters will die.

"It's always great when you can kill off some main characters," he said. "You have the chance to do something powerful and emotional. We do get to kill a few of them this time around."

The rather sombre teaser trailer for the movie was also revealed at the event.

Here's the official synopsis for the movie:

"From Academy Award®-winning filmmaker Peter Jackson comes The Hobbit: The Battle of the Five Armies, the third in a trilogy of films adapting the enduringly popular masterpiece The Hobbit, by J.R.R. Tolkien.

The Hobbit: The Battle of the Five Armies brings to an epic conclusion the adventures of Bilbo Baggins, Thorin Oakenshield and the Company of Dwarves. Having reclaimed their homeland from the Dragon Smaug, the Company has unwittingly unleashed a deadly force into the world. Enraged, Smaug rains his fiery wrath down upon the defenseless men, women and children of Lake-town.

Obsessed above all else with his reclaimed treasure, Thorin sacrifices friendship and honor to hoard it as Bilbo's frantic attempts to make him see reason drive the Hobbit towards a desperate and dangerous choice. But there are even greater dangers ahead. Unseen by any but the Wizard Gandalf, the great enemy Sauron has sent forth legions of Orcs in a stealth attack upon the Lonely Mountain.

As darkness converges on their escalating conflict, the races of Dwarves, Elves and Men must decide - unite or be destroyed. Bilbo finds himself fighting for his life and the lives of his friends in the epic Battle of the Five Armies, as the future of Middle-earth hangs in the balance."

The Hobbit: The Battle of the Five Armies will hit theaters on December 18.
