During the Q&A session, director Duncan Jones revealed that an early version of the script focused heavily on the humans, although it's now very balanced.

"It's about both sides. It's going to be red and blue."

The filmmaker also revealed the story centers on the battle between the human Anduin Lothar and the Orc Durotan, focusing largely on the Eastern kingdoms of Azeroth. However, Duncan Jones revealed that it has been a difficult task to find the right actor for Durotan.

"It's been hard to find an actor who looks like Durotan,. Every time I meet an actor I just try to squish his face."

Visual effects supervisor Bill Westenhofer compared the movie to Gladiator, teasing the actors

"The swords that are being built are the biggest swords a human being can wield."

While no cast members have been confirmed yet, Travis Fimmel has been offered a leading role, with Colin Farrell and Paula Patton in talks for other roles. We reported in August that production begins in January at CMPP Studios in Vancouver.
