Looks like Halo has been pulled by Fox and Universal. I'm guessing it has something to do with Peter Jackson's asking budget. Awful videogame movies get greenlight everyday, I could only imagine what price tag the people at Wingut films were asking. I don't really blame the studios, besides Resident Evil, there haven't been too many if any box office videogame hits. Of course it's possible that Halo would have changed that. I'm sure some other studio will eventually pick this up. I wonder if this will effect the game being produced by Jackson for the Xbox360?

As was previously confirmed, we deeply regret that both Universal and Fox did not choose to move forward with financing the Halo film under the original terms of the agreement. At this time Peter Jackson and Fran Walsh, along with their partner, Microsoft, have mutually agreed to postpone making a feature film based on the Halo video game universe until we can fulfill the promise we made to millions of Halo fans throughout the world that we would settle for no less than bringing a first class film to the big screen. We are fully supportive of Director Neill Blomkamp's vision of the film. Neill is a tremendously gifted filmmaker and his preliminary work on Halo is truly awe-inspiring. While it will undoubtedly take a little longer for Halo to reach the big screen, we are confident that the final feature film will be well worth the wait.
