The arrival of "The Hobbit: The Battle of The Five Armies" is inevitable. Slated for release on Dec. 17, the third installment was reported by Entertainment Weekly to present a climactic, 45-minute battle.

The word to describe is epic -- the title says it all. Director Peter Jackson noted, "There's a lot of logistics that have to be thought through."

The battle is set to take place at the foot of the Lonely Mountain, where armies will fight to the death in conquering Erebor's treasure.

"We have dwarves and men and elves and orcs, all with different cultures, with different weapons, and different shields and patterns and tactics," Jackson revealed, according to the report.

It must be noted that the eagles, with their appearance at the end of the "The Lord of The Rings" trilogy, will be making a comeback right at the war scene. Cinema Blend cited Jackson telling, "They're just part of the plan, not the saviors."

The battlefield scenes may be expected to hold variety. Jackson specifically cared about the audience feeling fatigued when anonymous characters take much airtime. "We have a rule that we're not allowed to go more than two or three shots of anonymous people fighting without cutting back to our principal characters," he pointed.

Can "The Battle of Five Armies" keep up with the hype of its predecessors?

Inspired by J.R.R. Tolkien's 1937 novel of the same title, Warner Bros' "The Hobbit" comes to the big screen in three separate parts. The first two were already released: "The Hobbit: An Unexpected Journey" came on 2012; "The Hobbit: The Desolation of Smaug" followed on 2013.

As recorded by Box Office Mojo, the 2012 film grossed $1,017,003,568 worldwide, while the next fell behind with $958,366,855.

Screen Rant reported that fans turned out to be disappointed with "The Desolation of Smaug," since its ending was a definite cliffhanger. The third installment, however, is Jackson's favorite.

He said via the outlet, "By the time we are done with this film, I think it will be the most emotional, the most tense of the three -- I think it's my favorite of the three." He looked at his work as a collective memory that will remind future generations of the tale that started with a ring.

All in all, Jackson has created a set of six films from the original "Lord of the Rings" to the current "The Hobbit."

Cast members of "The Hobbit: The Battle of the Five Armies" include Martin Freeman, Ian McKellen, Evangeline Lilly, Benedict Cumberbatch and Cate Blanchett. The New York Times listed full credits here.
