The Dash details:
This is the TV spot designed to run as a one-time special event during ESPNs Monday Night Football on December 4th. Featuring live actors and photo-realistic CG from leading Hollywood FX company, Digital Domain, the teaser was designed to give the Halo Nation a tiny, but evocative glimpse into the story of Halo 3 and a rare chance to see the Halo universe envisioned as a live action spectacle.
