Director Peter Jackson revealed "The Hobbit: The Battle of the Five Armies" plot spoilers when he spoke a the panel of the San Diego Comic-Con on Saturday.

"It's not as comical as the first Hobbit movie. It's getting closer to the tone of Lord of the Rings," he said.

The director also dished out more "The Hobbit: The Battle of the Five Armies" when he promised that characters will be killed off during the third and final installment of the J.R.R. Tolkien saga.

"It's always great when you can kill off some main characters," he added, according to MailOnline. "You have the chance to do something powerful and emotional. We do get to kill a few of them this time around."

"The Hobbit: The Battle of the Five Armies" trailer, meanwhile, hinted of the epic battle involving men, elves, dwarves, goblins and the shape-shifter named Beon, which was mentioned in the novel by J.R.R. Tolkien.

Martin Freeman's Bilbo Baggins begins: "One day I'll remember... Remember everything that happened here - the good, the bad, those who survived and those that did not."

Bard the Bowman (Luke Evans) can also been seen asking Thorin Oakenshield (Richard Armitage) in "The Hobbit: The Battle of the Five Armies" trailer, "Would you have peace or war?"

To which the dwarf king replies, "I would have war!"

Wega Digital senior visual effects supervisor Joe Letteri earlier weighed in on the title change from "There and Back Again" to "Battle of the Five Armies" and he agreed that it's for the best.

"Yeah because it is the climax, and you really just need to know that there is another battle for Middle-earth," he told the Collider. "The whole extension of 'The Hobbit's' story has really been to get us to the point where we understand when we leave it what's going to happen when you pick up the Lord of the Rings trilogy, and this really does kind of set that tone."
