This time around, the focus will switch to the friendship between Arthur and former foe Orm, played by Patrick Wilson.
“From the start, I pitched that the first film would be a Romancing The Stone-type thing – an action-adventure romantic comedy – while the second would be an outright buddy comedy. I wanted to do Tango & Cash!" Wan told Empire.
“Jason plays Arthur larger-than-life; Patrick plays the straight man. It’s not unlike what Will Smith and Tommy Lee Jones did in Men In Black – like Tommy, Patrick plays it dry, but very funny.”
Aquaman, meanwhile, is allowed to take a seat on the throne of Atlantis. However, when an ancient force breaks free, Aquaman must form an uneasy alliance with an unlikely ally to protect Atlantis and the world from irreparable damage. He also gets enemies in the form of Black Manta, who is out for revenge, and King Orm, who is also not very happy with his half-brother on the throne.
Aquaman and the Lost Kingdom will address climate change
Within the comic book series, the character of Aquaman is concerned with keeping the world's oceans clean, which touches on the serious subject of climate change, and Wan previously confirmed that the sequel movie will include environmental issues.
"I think people are going to be excited to see that this movie is quite different from the first movie in terms of tone. It's a little bit more serious, and we're dealing with issues like climate change," he previously toldThe Hollywood Reporter.
"We're not afraid to lean into that in a big way, because the 'Aquaman' comic book, even way back when, has always been environmentally conscious. He's always been someone who's fought to keep the ocean clean, and it feels more relevant in the world that we're living in today.
"So this movie has something to talk about, but it's still a fun action-fantasy movie."
Aquaman and the Lost Kingdom will star Momoa, Heard, Wilson, Dolph Lungren, Yahya Abdul-Mateen II, Temuera Morrison and Nicole Kidman.
