The Man of Steel fights to protect Metropolis against the same destructive force that obliterated Krypton in this animated adventure based on Geoff Johns and Gary Frank's 2008 comic book story arc Superman: Brainiac. Superman (voice of Matt Bomer) is preoccupied with Lois Lane (voice of Stana Katic) and training Supergirl (voice of Molly Quinn) when he learns that Brainiac (voice of John Noble) has set his sights on Metropolis. An unstoppable juggernaut whose power grows with each new city ne collects, Brainiac will put The Man of Steel's true strength to the ultimate test. Directed by James Tucker, Superman: Unbound also features voice work by Stephen Root, Alexander Gould, Diedrich Bader, and Frances Conroy.
