Jason O'Mara, Jeremy Sisto and even "Weird Al" Yankovic are among those lending their pipes to the 'Son of Batman' sequel.

Batman vs. Robin, the latest DC Universe original movie, has filled out its voice cast with a mix of newcomers and old favorites.

Jason O’Mara, the Terra Nova star who also plays George Washington on History’s Sons of Liberty, is back as the voice as Batman. Stuart Allan, who appeared on TV’s Bad Teacher, and Sean Maher, who played Shrapnel on CW’s Arrow, are returning as Robin/Damian and Nightwing, respectively. Also coming back is David McCallum (NCIS), who portrays Alfred.

The actors are reprising the roles they played in Son of Batman, DC’s last animated movie. Batman vs. Robin is a sequel to the 2014 movie and is inspired by the Batman: The Court of Owls comics storyline written by Scott Snyder and drawn by Greg Capullo.

The storyline tells of a secret society dating back to the early days of Gotham City that kidnaps children and raises them to be assassins.

New to the voice stable is Jeremy Sisto (Suburgatory), who will voice Talon, the Court’s almost unstoppable assassin.

Other newcomers include Grey Griffin (formerly DeLisle), whose credits run the cartoon gamut, as a character named Samantha, while "Weird Al" Yankovic will play the Dollmaker, a Batman villain who is the son of a cannibalistic serial killer.

Robin Atkin Downes (Superman vs. The Elite) will voice a character named Grandmaster and Peter Onorati voices a man named Draco.

Kevin Conroy, the voice of Batman from the classic Batman: The Animated Series, the Arkham video games and countless of other Bat-projects over the past 21 years, will guest-star (or guest-voice, if you will) as Thomas Wayne, Bruce Wayne’s father.

Jay Oliva, the Batman v. Superman: Dawn of Justice storyboard artist who has helmed five previous DC Animation features, is directing the project, which has a script by J.M. DeMatteis. James Tucker is producing.

The movie is produced by Warner Bros. Animation, DC Entertainment and Warner Bros. Home Entertainment and will be released this spring. The movie will have its world premiere at WonderCon, which runs April 3-5 in Anaheim.
