Before Jason Momoa was cast as the aquatic star of Aquaman in the DC Extended Universe, he had an audition for the role of Bruce Wayne/Batman in Zack Snyder's Batman vs. Superman: Dawn of Justice. Now, we have an idea exactly how it went for the Game of Thrones star as he geared up for a shot at becoming the Dark Knight.

"Yeah I kind of visualized, because it was a generic kind of just general scene from the Christian Bale movie The Dark Knight and I just, it was a big casting call so I knew a lot of people were going to be doing it and I just felt like it was a booby trap and I just didn’t want to do it," he said in a recent interview.

"So, we did it and I just pretended like Batman got killed in an alleyway and I picked it up and tried to play him like I was just down and out, poor, over it, just done wrong and he wasn’t afraid to punch even good people in the face," he told Fox Chicago's Jake Hamilton. "And just go like unforgivable about certain things but also like flawed, like the kind of person who would jump off a cliff and figure out on the way down what we’re going to do."

Despite being pessimistic and eventually not landing the gig, it still changed Momoa's career. It gave him a chance to impress Snyder enough to consider him as his potential Aquaman, the King of Atlantis in his future plans for DC's cinematic universe.

"So, they liked that and then I got called in about probably two to three weeks later and that’s when Zack laid it down and said ‘I want you to play Aquaman’, which was completely like ‘Excuse me?'" which, of course, led to a cameo in BvS before a full-time role in Justice League, all acting as precursor to director James Wan's Aquaman solo movie this month.

Directed by James Wan, Aquaman stars Jason Momoa as Aquaman, Amber Heard as Mera, Patrick Wilson as Ocean Master, Willem Dafoe as Nuidis Vulko, Yahya Abdul-Mateen II as Black Manta, Temuera Morrison as Thomas Curry, Dolph Lundgren as Nereus and Nicole Kidman as Queen Atlanna. The film opens on December 21.
