Although Jason Momoa is on the road promoting Warner Bros.' upcoming Justice League film, the star has been more than happy to divulge some details about his solo outing in Aquaman.

Talking with ComicBook.com, Momoa revealed some rather interesting details about the standalone Aquaman film. "In the story, we're going to see a couple different younger versions of me. And even before I was born, so you'll know where my mother came from, Atlantis," the actor said. "We've got to establish seven different kingdoms and the threat."

The seven kingdoms Momoa mentions are most likely drawn from an aspect of Aquaman's comic book history, in which there were originally seven separate Altanean kingdoms. At one point, four of them were lost or destroyed, leaving three which into very different societies. It's also likely what the "Unite the Seven" tagline on an early Aquaman poster referred to, though many fans were quick to assume it meant there would be seven members of the cinematic Justice League.

"Surpassing Justice League, this moment in time is his call to become king. The only thing that can save Atlantis is me fighting my own brother," Momoa continued, referring to Orm Marius, better known as Ocean Master (played by Patrick Wilson). " There's a big battle, and there's an epic [fight]. It's also a big road movie, because we travel all over the world. It's got that Star Wars quality of gigantic ships and guys riding sharks. It's going to be this whole world you've never seen before. You're going to see him start as this guy who probably rides bikes, works on cars. You get to see him this one way as kind of a dirty, dark, drunkard, and then turn into this regal king."
