Like us, you've probably been wondering what sort of work (apart from directing people in costumes and laying on the special effects) went into Microsoft's now-legendary Halo 3: ODST live-action short, "The Life." Its creators must have anticipated our curiosity because they've put together a short-but-sweet behind the scenes video, which includes a rough cut of a scene that didn't make it into the final production.The micro-documentary also reveals some surprising trivia about the shoot, including the fact that the opening funeral scene was shot inside the cooling tower of an operating nuclear power plant. Oh, and the battle sequence? They filmed it at the bottom of a coal strip-mine. Really? We could have swarn it was New Mombasa.
