Reach may have fallen but it looks like the Halo movie may be rising from its proverbial ashes if what Vulture says is true. Apparently Steven Spielberg is after the rights for the Halo movie. That's some pretty big progress right there.
According to Vulture, Dreamworks is looking to reference the Halo novelizations and other such materials aside from what Universal and Fox used in order to avoid any legal conflict.
This claim is currently unconfirmed so take it with an incredibly large pinch of salt. Maybe make it a bowl.
