When The Hobbit: The Battle of the Five Armies finally comes out on December 17th, its ending will be suitably epic. In fact, the titular battle will apparently last 45 minutes, and is so huge and complicated that director Peter Jackson had to diagram it out. However, this diagram isn't quite as epic as the battle probably will be.

Here's Jackson explaining the monumental task he took on in creating the trilogy's final act to Entertainment Weekly:

"There's a lot of logistics that have to be thought through," says Jackson. "We have dwarves and men and elves and orcs, all with different cultures, with different weapons, and different shields and patterns and tactics."

The mega-melee takes place at the foot of the Lonely Mountain as various armies vie for the newly reacquired dwarven treasure of Erebor. Like so much in Jackson's Middle-earth, it represents filmmaking on the largest possible scale. "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 says. " 'Are they going to fill up the valley or look like a speck?' Then we could start drawing the arrows on the schematics."


And thus, to help keep track of all these warring bodies, Jackson turned his keen imagination and less keen drawing skills to make the following:


It looks like something I probably doodled on the back of my math homework during French. I take that back — I would have almost certainly drawn a dragon or two on there to spice things up. I also would have likely drawn the Aerosmith logo, too. Maybe Metallica, if I was feeling really rebellious.
