Speaking to Collider on June 28, Letteri and Lemmon suggested that the effects team was focussing on the highly anticipated battle scene in Battle of Five Armies. They suggested that they were halfway into the project.

"The Hobbit's going great.  We've got a lot of stuff already turned over to Peter, we're in the middle of it, we're cranking through it," Letteri said.

Letteri went on to speak about how the ending of this movie would lead into and help fans better understand the Lord of the Rings trilogy.

"Yeah because it is the climax, and you really just need to know that there is another battle for Middle-earth," he said." 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."

He went on to add that The Hobbit: The Battle of Five Armies would serve as the "peaceful interlude" before the Lord of the Rings trilogy.

"We hope so, that's the whole idea," he said. "You've got all these worlds of Middle-earth-when I say worlds I mean the elves and the orcs and everyone sort of coming together in this final battle.  It's got to give you that sense that if this isn't won, there is no Lord of the Rings; everything's over at this point. So this has to happen, and that allows the sort of peaceful interlude you have before the next trilogy starts."

The Hobbit: The Battle of Five Armies will hit theaters on Dec. 18.
