I’m going to go out on a limb and say Castle and Firefly star Nathan Fillion likes comic books. Did you see this week’s episode of Castle which aired on Monday night?

If not, take my word for it, the guy likes comics. That probably explains why he’s joining the cast of the latest Warner Bros. animated opus Justice League: Doom to reprise his role as Green Lantern.

He’s not the only one either. Tim Daly will also be returning to once again take on the role of Superman in the new project. Good times.

Here’s the scoop on the new movie:

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.”

Fortunately for fans, Fillion and Daly won’t be alone in the cast. Also returning are Kevin Conroy as Batman, Michael Rosenbaum as Flash, Susan Eisenberg as Wonder Woman and Carl Lumbly as J’onn J’onzz/Martian Manhunter.

Warner Home Video will premiere the Justice League: Doom trailer during New York Comic Con on Friday, October 14. Look for the full film to be released early next year.

While fans are anxiously awaiting the next big screen incarnations of Superman or Batman, Warner Bros. animation has been hard at work turning out some great animated content for the small screen. One such bit of awesome is the Justice League series.

The show recently wrapped up its second season and now the announcement has come out that the entire season will be available on Blu-ray soon. Here’s all the scoop from the official press release:

Superman, Batman, Wonder Woman and their DC Comics super hero comrades burst onto the scene in dazzling high definition as Justice League: Season 2 arrives on Blu-ray™ for the first time. Produced by Warner Bros. Animation, the series’ 26-episode second season will be distributed on Blu-ray™ by Warner Home Video on July 26, 2011 for $39.99 SRP. Order due date is June 21,2011.

Amping up the action, intrigue and epic storylines from its successful first season, Justice League: Season 2 crossed new boundaries in its portrayal of the greatest fighting force in the universe. Comprised of Superman, Batman, Wonder Woman, Flash, Green Lantern, Martian Manhunter and Hawkgirl, the Justice League wages war with their own personal demons and internal issues of mistrust and insecurity, all the while battling a most heinous collection of villains led by Darkseid, Brainiac, Solomon Grundy, Amazo, Joker, Vandal Savage and more.

Justice League Season 2 was produced by Bruce Timm and James Tucker. The core voice cast features George Newbern (Superman), Kevin Conroy (Batman), Susan Eisenberg (Wonder Woman), Michael Rosenbaum (Flash), Phil LaMarr (Green Lantern) Carl Lumbly (Martian Manhunter) and Maria Canals Barrera (Hawkgirl).
