How the Warcraft movie makes one film out of a universe of stories

What do you do when you have too many stories to tell — and only one movie in which to tell them? That’s the problem Duncan Jones, the director of the upcoming film based on the Warcraft universe, faces.

Warcraft is now in post production and scheduled for March 2016. Jones is best known for his well-received 2011 thriller Source Code (in which Jake Gyllenhaal is a soldier who must re-enact the last eight minutes before a train explodes). He spoke on a panel today at the BlizzCon convention in Anaheim, Calif., on the making of the movie and its special challenges.
