The Independent reported from a press conference at which Jackson spoke on December 2. The director stated that it's not because he didn't want to but because the rights two only two of Tolkien's works had been sold, so he couldn't adapt another of the literary greats work.

"The Tolkien estate owns the writings of Professor Tolkien - The Hobbit and The Lord of the Rings were sold by Professor Tolkien in the late Sixties, the film rights," Jackson said. "But they are the only two works of his that have been sold. So without the cooperation of the Tolkien estate, there can't be more films."

Recently, director Peter Jackson also dished about the final battle scene in the movie, and the logistics that went behind the making of it.

Speaking to Entertainment Weekly, Jackson spoke about the technicalities and preparation for the massive conclusion to The Hobbit trilogy.

The director stated that the first priority was to chalk up the landscape for the grand event, and how the various armies would be placed in the scheme of things.

"Before we could loose the first arrow, we had to design the landscape itself and figure out, 'Okay, if we have 10,000 orcs, how much room are they going to take up?' " Jackson said. " 'Are they going to fill up the valley or look like a speck?' Then we could start drawing the arrows on the schematics."

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