Looks like Master Chief fans will have something more to look forward to in regard to the E3 teaser trailer for Halo 3. After audio director Marty O'Donnell's loose lips let slip that something was coming down the pike, the team decided to make an official announcement.
From this week's Weekly Update:
Some of our sharp-eyed fans may have noticed Marty hinted at an upcoming documentary on Bungie.net. It was supposed to be a surprise, but since the man himself gave it away, we can in fact reveal that we have a documentary short that shows the process and people involved in making the E3 trailer, complete with some never before seen scenes (think angles, really) from the trailer.
If you've ever wanted to know what goes on behind the scenes at Bungie—in the trailer creation department that is—all of your burning questions will be answered. Hopefully, they'll be showing off a bit more than just "never before seen angles".
