After recent troubles with previous disributers Fox and Universal, the Halo movie has been left without any disributers as Paramount and Warner Bros. have passed over the Halo project:

"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."

While it may be disappointing, it also shows how dedicated the crew behind the film are. We can only hope that in the future the film will find suitable partners and we will finally see the film on the big screens.
