*this is Brand X
The commercial sounds like it will be pretty badass from what they've said about it. It's a mix of CG and live action created by Digital Domain. It seems like they are using it for many purposes, A) to spread word that Halo 3 is coming (not that anyone who cares about the game didn't know), and B) show potentially what could be seen if/when a Halo movie does come out.
