“I have so much invested into it. I love this character. I love what it represents,” said Momoa, as reported by TheWrap.

Wan also discussed the return of Black Manta, played by Yahya Abdul-Mateen II.

“Black Manta is still seeking his vengeance to try to kill Aquaman. That’s going to be something that’s exciting for the audience,” said Wan. “It’s a globetrotting story. We visit so many different worlds. This movie isn’t afraid to embrace its fantasy.”

“Aquaman And The Lost Kingdom” hits theatres on Dec. 16, 2022.
