Aitken was one of the native New Zealanders who worked on both the Lord of the Rings trilogy and The Hobbit: Desolation of Smaug.

While speaking about his craft and working on the previous films with director Peter Jackson, the visual effects supervisor also spoke about what's coming up in the third Hobbit movie, suggesting that, for fans, the wait will be worth it.

New Plot Details for The Hobbit: There and Back Again Revealed?

"There's going to be a battle. That's not too much of a surprise for people. It'll be spectacular," he said. "Film one was the set-up, getting to know the characters and everyone up and on the way. Film two was the consolidation of all of that and getting to know what drives Thorin for the quest of his homeland and what drives Bilbo. Film three is going to be the payoff for all of that." 

In a recent interview with Hypable, Jackson spoke about his decision to break the story into three parts, making it a trilogy, suggesting he wanted to give it a similar structure as he gave The Lord of the Rings.

"You want the narrative to be told either through the dialogue or the actions, so that's really why we ended up with the depth and exploring the character depth that we had done on The Lord of the Rings," he said.

The director went on to speak about needing three parts to engage the complexity of the story.

"I was also acutely aware that there was going to be, ultimately, when this cycle of releasing a movie each year is done, you're going to end up with six films. The Unexpected Journey being the beginning and the Return of the King being the end. I did want to have a unity. I didn't want to make The Hobbit feel any more simple. We wanted it to feel like it was the same," he said.

The Hobbit: There and Back Again will hit theaters on Dec. 18.
