The film follows the titular character Bilbo Baggins as he accompanies Thorin Oakenshield and his fellow dwarves on a quest to reclaim the Lonely Mountain from the dragon Smaug. The film also features the vengeful pursuit of Azog the Defiler and Bolg, while Gandalf the Grey investigates a growing evil in the ruins of Dol Guldur. The ensemble cast includes Ian McKellen, Martin Freeman, Richard Armitage, Benedict Cumberbatch, Evangeline Lilly, Lee Pace, Luke Evans, Ken Stott, James Nesbitt, and Orlando Bloom.

Fran Walsh, Philippa Boyens, Peter Jackson and Guillermo del Toro wrote the screenplay. The films were shot simultaneously in 3D at a projection rate of 48 frames per second, with principal photography taking place around New Zealand and at Pinewood Studios. Additional filming took place throughout May 2013.
