Heroes (2006 - 2010): Heroes Volume 3: Villians

Heroes creator Tim Kring debuted a new Heroes trailer over the weekend at the Jules Verne Adventure Film Festival of Los Angeles (huh?!), which features never-before-seen footage from Volume III, "Villains." Where'd the footage come from, you ask? Well, it turns out that the show managed to shoot a bunch of scenes for Episodes 12 and 13 before production ground to a halt. But those episodes are incomplete and, therefore, can't air until the conflict is resolved.
