Steven Spielberg will executive produce a live-action TV series based on the video-game franchise Halo, he announced today at an Xbox event. The show, World of Halo, is for Xbox Live — which means Microsoft is getting into the original programming game, too. On the one hand, hey, anyone would kill to get Steven Spielberg onboard with a project! On the other hand, his most recent shows are the nonentity Falling Skies and the short-lived Smash, The River, and Terra Nova. No word yet on when exactly the show will launch or what exactly we'd have to do to get Beyoncé's "Halo" in there somehow.
