The first look at The Hobbit: The Battle of Five Armies has been revealed.

A two-minute trailer for the final film in Peter Jackson's trilogy was posted onto The Hobbit's Facebook, the New Zealand Herald says.

The trailer, which debuted at Comic Con in San Diego over the weekend, showed the dragon Smaug setting Lake-town ablaze, Cate Blanchett's royal elf Galadriel kissing the forehead of Ian McKellen's beleaguered wizard Gandalf and legions of elves and orcs racing into battle.

The Hobbit: The Battle of Five Armies is due for release on December 12.
