The Hobbit An Unexpected Journey 2012

Approaching his 111th birthday, the Hobbit Bilbo Baggins begins writing down the full story of his adventure 60 years earlier for the benefit of his nephew Frodo.

Long before Bilbo's involvement, the Dwarf king Thrór brought an era of prosperity for his kin under the Lonely Mountain until the arrival of the dragon Smaug. Destroying the nearby town of Dale, Smaug drove the Dwarves out of their mountain and took their hoard of gold. Thrór's grandson, Thorin, sees King Thranduil and his Wood-elves on a nearby hillside, and is dismayed when they leave rather than aid his people, resulting in Thorin's everlasting hatred of Elves.
