Animation Magazine has these new screenshots of the first full season, along with news that it will officially kick off its 26 episode run in March 2012. Green Lantern will be accompanied by more, as yet unannounced, DC related offerings that will comprise the Cartoon Network's 'DC Nation' programming block.

Justice League: Doom finds Superman, Wonder Woman, Flash, Green Lantern, Martian Manhunter, Cyborg and Batman on their heels when a team of super villains discover and implement the Dark Knight’s “contingency plans” for stopping any rogue Justice League member. The story is inspired by Mark Waid’s much-heralded “JLA: Tower of Babel.”

The film features the voices of Nathan Fillion (Castle) as Green Lantern, Tim Daly (Private Practice) as Superman, and a grand reunion of actors who provided the voices of the Justice League for the cartoon of the same name and its follow-up, Justice League Unlimited, including Kevin Conroy (Batman: The Animated Series) as Batman, Michael Rosenbaum (Smallville, Breaking In) as Flash, Susan Eisenberg (Superman/Batman: Apocalypse) as Wonder Woman and Carl Lumbly (Alias) as J’onn J’onzz/Martian Manhunter. Bumper Robinson (A Different World, Transformers: Animated) joins the cast as Cyborg. The cast features three villainous alumni of the Justice League animated series: Phil Morris (Smallville, Seinfeld) as Vandal Savage, Olivia d’Abo (The Wonder Years) as Star Sapphire, and Alexis Denisof (Angel) as Mirror Master. Also opposing our heroes are Carlos Alazraqui (Reno 911) as Bane, Paul Blackthorne (The Dresden Files) as Metallo, and Claudia Black (Farscape, Stargate SG-1) as Cheetah. David Kaufman (Danny Phantom) also reprises his Justice League role of Jimmy Olsen.

The filmmaking team includes executive producer by Bruce Timm, director Lauren Montgomery, producer Alan Burnett and dialogue/casting director Andrea Romano. Justice League: Doom is the final DC Universe film script from the late Dwayne McDuffie.

Voice cast members and filmmakers will be announced as confirmed for the event. The Paley Center for Media is located at 25 West 52nd Street, New York, NY.

Warner Bros. has announced that the upcoming DC Universe animated feature Justice League: Doom will be released on Blu-ray and DVD on February 28, 2012.

Based on Mark Waid's "Tower of Babel" storyline from JLA, the film see the Justice League up against a foolproof plan designed to ht them at their weak points and utterly defeat them - a plan devised by Batman.

Doom is scripted by the late Dwayne McDuffie, who, among his many contributions to comics and animations, elevated animated comics adaptations to new heights of greatness with All-Star Superman. It boasts a voice cast of DCU mainstays including Kevin Conroy (Batman), Tim Daly (Superman), Michael Rosenbaum (Flash), and Susan Eisenberg (Wonder Woman) as well as Nathan Fillion who took over the voice of Green Lantern in the recent Emerald Knights. Carl Lumbly voices Martian Manhunter, and Bumper Robinson plays new addition Cyborg.

Here's a quick preview clip of this week's new episode of Young Justice, "Secrets."

It's Halloween and Artemis and Zatanna go to Manhattan for a night on the town. Unfortunately they find themselves hunted by Harm, a pycho in training who is hiding a deadly secret...

Not gonna lie, this looks pretty awesome. A fuzzy quality version of this has been floating around the 'net since it debuted with the Green Lantern pilot last week, but here finally is a high quality version of the DC Nation 2012 promo.

Check out this behind-the-scenes look at the making of the upcoming Justice League: Doom. The movie features a DC Animated Universe dream team including stalwarts like Kevin Conroy as Batman, Tim Daly as Superman and Michael Rosenbaum as the Flash along with newcomer fan-favorites like Nathan Filion as Green Lantern, in an adaptation of the classic Mark Waid JLA storyline, "Tower of Babel".

Batman's greatest rival, Ra's al Ghul continues his quest to save Earth from humanity by thinning the ranks of the human populace. But after being thwarted over and over again, Ra's seeks to distract Batman by stealing the bodies of his dead parents while he enacts his nefarious plot. And to insure that Superman, Wonder Woman, Green Lantern, the Flash and the rest of the JLA do not interfere with his plans, he individually defeats each of the heroes using strategies developed by Batman himself! And when the League learn of his betrayal, they look to expel the Dark Knight from their ranks.

Batman fans are already mourning the departure of Mark Hamill, who has stated that he doesn't intend to return as the voice of The Joker. However, when a fan suggested on Twitter that the actor return for an animated adaptation of Alan Moore's classic story Batman: The Killing Joke, Hamill replied that he would "come back for THAT!" So let's start the campaign, guys and gals! The Killing Joke is even canon in the new DCU, so there should be nothing stopping DC from doing a Killing Joke animated feature, which would surely be a big hit with everyone except the notoriously difficult to please Moore.

Despite the New 52, numerous Batman animated reboots, and an upcoming Green Lantern CG series, the classic DC Animated Universe established in Batman: the Animated Series, Superman, and Justice League/Justice League Unlimited, is still alive and well. It's just not quite as active, resurfacing periodically in movies like the upcoming Doom, an adaptation of Mark Waid's "Tower of Babel" JLA storyline set for release in early 2012.

Warner Bros. has released the first trailer to the public after debuting it at Comic Con, and I'm psyched. I think it looks great, but I'm a sucker for the DCAU. Check it out and let me know what you think.
