The late Dwayne McDuffie (All-Star Superman, Justice League: Crisis on Two Earths) penned this epic story of heroism and betrayal based on the critically-acclaimed, best-selling Justice League graphic novel. Directed by Lauren Montgomery (Superman Doomsday, Green Lantern: First Flight) and produced by Emmy®-winning animation legend Bruce Timm, this apocalyptic tale details the nefarious plot of villain Vandal Savage, who discovers Batman’s contingency plan to defeat the Justice League should any of them go rogue. Now, backed by his own army of supervillains, Savage sets out to take down the Justice League one hero at a time! Featuring Tim Daly, Kevin Conroy, Susan Eisenberg and Nathan Filion reprising their roles as Superman, Batman, Wonder Woman and Green Lantern respectively, this animated saga also features the voice work of Smallville’s Michael Rosenbaum, Olivia d’Abo (Law & Order: Criminal Intent) and more.
