Sam Raimi is no longer working on the World of Warcraft movie, according to a report on CraveOnline. Speaking the director at ComicCon, Raimi said that “Actually, they don’t have me directing World of Warcraft anymore because when I took the Oz job, they had to move on to another director. They had to start making it.”
At least they're getting on with it. I'd expect a trailer, with announcements of the cast, at the next Blizzcon.
