It seems like the dwarves will be divided into two factions with Thorin's rapid descent into madness in The Hobbit: Part 3, according to the film's co-writer and producer, Philippa Boyens.

In a recent interview with Empire, Boyens spoke about the last film in The Hobbit trilogy and her particular interest in Thorin's storyline.

The producer cautioned that she was in no position to dish out spoilers or too much information about The Hobbit: There and Back Again, suggesting that the film was still in the stages of pre-production.

"I can legitimately say right now that the third film doesn't exist," she ssaid. "Pete's cutting it. As an entity, it's coming together. Actually that's not true - we have a rough assembly, so to speak, of the shape of the film and the performances. I am excited, because one of the storylines I care a lot about is the Thorin one."

Speaking of Richard Armitrage's character, who leads the dwarves into battle to reclaim what's theirs, she stressed on his superb portrayal of the dwarf king.

"Richard Armitage is extraordinary, as Thorin descends into madness," she said.

As Boyens shared her thoughts on The Desolation of Smaug cliffhanger she said she felt the intensity of the shock with the audiences. The writer also suggested that that surprising end is the starting point for a darker storyline.

"It felt so natural that I got a shock when the audience got a shock! If you can imagine what transpires next and what's coming, it's quite a huge chunk of storytelling," she said. "Not only that, but you enter into the tone of the third film, which is very definitely - as is the book, by the way - moving towards the world of Middle-earth as it becomes in Lord Of The Rings. Some dark stuff goes on."

As Boyens started opening up about the third film she also spoke about the internal friction amongst the dwarves and how the split came to be.

"We made that decision [so we would] experience the attack on Lake-town through the eyes of people we've come a long way with," she said. "We wanted some of the dwarves to understand what happened in that firestorm, that holocaust that rains down upon Lake-town. Bofur (James Nesbitt) comes more into his own in the third film. A rift begins to open up. And I can't say much more without going into spoilers for film three, but it's primarily because we needed him to be there when the dragon attacks."
