"We have all felt the squeeze and changes of these transformational times… A revolution is unfolding ~and our family is of no exception… feeling and growing from the seismic shifts occurring", Momoa wrote.

Four years on from Aquaman's initial release, Jason Momoa is set to return to the big screen as the King of Atlantis later this year.

The movie – which also stars the likes of Amber Heard, Yahya Adbdul-Mateen II, Patrick Wilson, Dolph Lundgren and Nicole Kidman – recently released its official synopsis.

"When an ancient power is unleashed, Aquaman must forge an uneasy alliance with an unlikely ally to protect Atlantis, and the world, from irreversible devastation," it reads.

Despite its pretty heavy premise, Momoa admitted that he "giggled" while reading the script. "Even on the page, it was absolutely wonderful," he teased. "There is so much going on...

"There's a lot of fun. There's a lot more heart, there's a lot more risk."

Aquaman and the Lost Kingdom currently has a release date of December 16, 2022.
