Be warned, there will be spoilers for Justice League: War, which debuts on Blu-ray and DVD February 4, so read on at your own risk.
Last night, Warner Bros. Home Entertainment held the world premiere of Justice League: War, an adaptation of DC's New 52 comic book "Origins" by Geoff Johns and Jim Lee, where the studio revealed plans for more New 52 adaptations, including a future movie that was teased in an end credits scene. Since the adaptation replaced Aquaman with Shazam as a founding member of the Justice League, this scene reveals that the studio has much bigger plans for Aquaman.
The scene features Orm (Ocean Master), the brother of Aquaman, rising from the sea carrying an old man's dead body to say, "The Surface Dwellers have killed our king. This is an act of war. And they will pay." The line is a reference from another New 52 comic book entitled Throne of Atlantis, which crosses over between Aquaman and Justice League stories.
When asked specifically if a Throne of Atlantis movie is in the works, a Warner Bros. representative had this to say.
"You'll see a movie with Atlantis in the title."
The studio said they wanted to save Aquaman's introduction for this unspecified movie revolving around his character, instead of having him as a part of the Justice League ensemble. Warner Bros. has two more animated adaptations debuting in 2014, Son of Batman and Batman: Assault on Arkham, both of which are adaptations of the original comics and not the New 52 line, so this Aquaman/Throne of Atlantis movie will likely debut in 2015.
"It's our own version of the New 52 universe, our own start."
However, the producer insisted they still plan on adapting original stories from DC's 75 year history.
