This is because the Halo movie was postponed and then it got cancelled so i believe that they aren't making it any more, sorry to disappoint you.

They have cancelled it, but some have said it still will be made but at a waaaaaay later time.
Sadly, no, they have cancelled the movie. The writers didn't even know about it until after the movie has been cancelled. :(
There were plans, but it has been cancelled.
Halo is owned by Microsoft. Nintendo did not have the rights to create that at all.

There was going to be a Halo MMOG but it got cancelled.
