Looks like someone went and uploaded the Son of Batman featurette and preview on to YouTube that is part of the Justice League: War animated movie.
Below you can check out almost ten minutes of footage and interviews.
Info:
The upcoming animated movie Son of Batman introduces Damian, the child Bruce Wayne never knew he had. The story is based on a 2006 comic-book arc written by Grant Morrison in which Batman learns that he has a violent, unruly pre-teen son, secretly raised by the terrorist group the League of Assassins.
The voice cast features Jason O’Mara as Batman/Bruce Wayne; Stuart Allan as Damian; Morena Baccarin as Talia, Damian’s mother; Giancarlo Esposito as Ra’s Al Ghul, leader of the League of Assassins and one of Batman’s most notorious enemies; David McCallum as butler Alfred Pennyworth; Xander Berkeley as Kirk Langstrom (aka Man-Bat); and Thomas Gibson plays the master assassin Deathstroke.
Son of Batman comes out late this spring on DVD, Blu-ray and for digital download. The movie will have its world premiere at WonderCon over Easter weekend in Anaheim, Calif.
