Jason Momoa takes pride in Aquaman and the Lost Kingdom writing credit

Jason Momoa is "extremely proud" of his writing credit on 'Aquaman and the Lost Kingdom'.

The 44-year-old actor has helped pen the script for the concluding picture in the DC Extended Universe (DCEU) – in which he reprises his role as Arthur Curry/Aquaman – and is delighted to have helped craft the story for a character he adores.

Speaking at the CCXP convention in Sao Paulo, Brazil on Sunday (03.12.23), Jason said: "It's pretty much all me, and I love it. I'm extremely proud of it.

"There's a lot of things you want to do and fulfil as an actor, and also for the fans, and for myself. When we finished the first one, I had a lot of ideas. And I started to put them down, just put down in my heart and my love for the character."

The 'Game of Thrones' actor also recalled the "nerve-wracking" experience of pitching his ideas to director James Wan and bosses from both DC and Warner Bros.

Jason said: "I've never done that before. I pitched my own idea but I'm like, 'They can't fault me on this, because I love this character and I've played it for so long. Here's some ideas that I would like to do.'

"And they responded really well to it, and then James liked a lot of ideas, and then they took that and ran with it and took it another level."

The movie is set for release later this month and Wan previously revealed that climate change will feature as a key plot point in the superhero sequel.

The 46-year-old filmmaker told The Hollywood Reporter: "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.

"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."
