"Source Code" director Duncan Jones is tapped to helm the live-action film, while "Blood Diamond" scribe Charles Leavitt will write the script. The movie adaptation was first announced back in 2006. "Spider-Man" director Sam Raimi was initially attached to the project, but he bowed out last year.

The project is now expected to start production in January 2014. "Warcraft" series is an online multiplayer role-playing game taking place in a high-fantasy medieval-like setting where gryphons, dragons, zombies, werewolves and elves exist.u00a0
