"Warcraft was teased, albeit briefly, with a simple title treatment. To be directed by Duncan Jones (Moon), the film is based on the game series. Tull said they are taking their time with this one and placing a "very high bar" on it, "because, frankly, video game movies have not fared very well." They want a great script and are taking the property very seriously. Expect more updates over the next few months."
