A movie based on Blizzard’s Warcraft universe will go into production next year.

The first details of the movie were revealed at BlizzCon in a panel that include the film’s director, Duncan Jones (Source Code, Moon), Blizzard’s Rob Pardo, Chris Metzen and Nick Carpenter, and visual effects supervisor Bill Westenhofer.

The movie is to be an origins story that recounts the first contact and conflict between the orcs and the humans. Jones said an early draft of the film focused almost exclusively on the humans and the Alliance, but soon became about “being a hero no matter what side you're on.”

Chris Metzen added that the goal was to have every Warcraft player’s person story reflected in the movie.

“To tell a story where you’re really, honestly telling it from both sides – especially a war film – is unusual,” Jones said. “The fact that we’re been able to get an opportunity to do that is, on a story level, breaking a few barriers. I don’t think you’re going to see a lot of films with this structure.”

"We had been working on multiple iterations of the story in the years before we met [with Jones]," Metzen said that in a game with so many races and characters, working on the script "was a process of honing in on what are the themes that are universal, constructing a story that sings to everyone’s faction and race and finding the touch points that are the broadest themes so everybody wins."

The Warcraft movie is targeting a December 2015 release.
