In this fascinating short, you'll see some of the teamwork, thought processes and imagination that went into this Halo 3 teaser. You'll see the actual orchestra and choir session, some of the in-studio production work and interviews with some of the key folks who worked on the E3 presentation. You won't see everyone - lots of folks who slaved over hot keyboards to make this trailer a reality were simply too busy to be interviewed - and to them, our heartfelt appreciation.

But you will see some footage from the trailer that didn't make the cut, and you'll see angles and views from the realtime footage that we kept for this piece. And if you look very, very carefully, you'll see hints of things to come. Nothing too dramatic, but the fans will spot stuff, of that we're certain.
