As for World of Warcraft, they took so long with the development and script-by-committee that the momentum of the game cooled and took the film down with it. If the film had come out maybe 2-3 years ago, they might have been able to make a serious franchise out of it. But the game's cachet has worn off. WoW's subscriber numbers might still be the envy of the MMO industry, but they're not enough to help bankroll a $200-300 million dollar fantasy film. 'John Carter's' failure has made studios leery of getting behind an untested IP's prospects in the marketplace. Not to mention that films based on videogames have, so far, had a pretty poor track record.
