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.
