Ok dont know how factual this is (so I will tag it with Rumor) but according to sources speaking with film site IESB, Steven Spielberg is in talks to oversee the producing role of a new Halo movie!

Apparently Spielberg has read and is quite impressed with Stuart Beatties screenplay (which I think revolves around the early period of master chiefs life and the events leading up to the fall of Reach).

No other solid news but I am sure we will be following up on this as more is known.
