Rumors are that work on a Halo movie is beginning to spin up again. The reports state that filming will begin in 2012 and be conducted by Steven Spielberg and his production company Dreamworks.

There have been reports circulating since 2009 that Spielberg was interested in making a Halo film based on the source material of the novels. The reasoning to use the novels instead of the games was to avoid playing production fees to Universal and Fox for their abortive attempt to make a Halo film.
