Three months ago Warner Bros. released a two-minute teaser trailer for The Battle of the Five Armies. Now the “official main trailer” for the movie has been released. The video shows that many fan-favorite characters from the Lord of the Rings movies will make appearances in the final Hobbit chapter.

The Hobbit: The Battle of the Five Armies will depict the climactic events of J.R.R. Tolkien’s The Hobbit. Titular character Bilbo Baggins, having awoken and enraged the dragon Smaug, must now join Gandalf and Thorin Oakenshield’s band of dwarves to defend the Lonely Mountain. The battle for which the third movie is named will also be a part of the story, pitting men, dwarves, elves, goblins, and other Middle-Earth creatures against each other in a sequence that’s sure to rival the Battle of the Pelennor Fields as it was depicted in Jackson’s The Lord of the Rings: The Return of the King. Meanwhile, a dark power familiar to Lord of the Rings fans has begun to make itself known again.

Richard Armitage, who plays Oakenshield in the Hobbit movies, complimented Jackson and company on the trailer, saying that he is “proud” to have starred in the movies.

The world premiere of The Battle of the Five Armies will take place on December 1 at Leicester Square in London. The premiere will be attended by much of the movie’s cast and crew. Warner Bros. has announced that the premiere festivities will be live-streamed.
