Armitage spoke to ScreenCrush in an interview dated August 5. While talking about playing Thorin and how close he came to being the character off set as well, Armitage stated that he had to stay in character for a whole day one time.

"We wanted to go camping as the Dwarves. And there was one day on The Hobbit when we were at the top of a mountain and we were left there all day in our costumes," Armitage said. "So, we sort of stayed in character all day and we did helicopter shots and that was when I thought, You know what? If I can stay with the character for 12 hours, maybe I'm inside of him? It doesn't come and go."

The actor also spoke about what legacy The Hobbit series would leave behind.

"I think when The Lord of the Rings was made, it just felt like such a breakthrough in terms of cinematography," he said. "Since then, there's been a huge shift in the technology. I think The Hobbit has been a big experiment in technology."

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.
