Although a lot of Aquaman-centric content was cut from Justice League, the character's solo movie -- which releases late next year -- will have a chance to explore the hero in depth. Now, we know where he will start off, both physically and emotionally

"When we find Arthur, he's hiding on the edges of society," Momoa said on Justice League: The Art of the Film, a behind-the-scenes peek about the making of Justice League. "He knows what his power is, but he doesn't know how to channel it. He hasn't accepted himself as king. He's been running from both sides, human and Antlantean [sic], and he’s been really that outlaw and renegade and the rebel."

Justice League touched on Aquaman's frustration with his Atlantean heritage during a conversation between him and Mera (Amber Heard). However, that's the extent of what we learned about his background in the film.

In October, James Wan's Aquaman wrapped production. The film, which will mark Aquaman's first solo outing on the big screen, has been described as "Star Wars underwater," with Wan promising that fans can expect a "swashbuckling action-adventure, sort of high seas adventure story."

Arriving December 21, 2018, Aquaman stars Jason Momoa as Aquaman/Arthur Curry, Willem Dafoe as Nuidis Vulko, Amber Heard as Mera, Patrick Wilson as Ocean Master, Yahya Abdul-Mateen II as Black Manta, Temuera Morrison as Thomas Curry, Dolph Lundgren as Nereus, Nicole Kidman as Atlanna, Ludi Lin as Murk, and Michael Beach as Jesse Kane.
