The Hobbit: The Battle of the Five Armies
What they share

What The Hobbit: The Battle of the Five Armies is
Erebor, winter, a dragon's roar fading. Armies of orcs, dwarves, elves, and men clash over treasure, Bilbo caught in the chaos. Jackson's trilogy concludes with Middle-earth's fate hanging in the balance.
