Based on Darwyn Cooke's award winning graphic novel, this thrilling adventure reveals the origin of the Justice League. With Cold War paranoia putting Superman, Batman, and Wonder Woman under government suspicion, only the gravest threat imaginable can force these heroes - along with an army of newcomers including The Flash, Green Lantern and Martian Manhunter - to unite in a spectacular showdown to save the world.

David Boreanaz (Angel), Brook Shields (Suddenly Susan), Lucy Lawless (Xena: Warrior Princess), Kyra Sedwick (The Closer), Neil Patrick Harris (How I Met Your Mother), Jeremy Sisto (Law & Order) and Kyle MacLachlan (Sex And The City) headline the stellar voice cast of this epic saga of how Earth's greatest champions formed the most power alliance for good ever assembled!
