The news was announced on Instagram by Aquaman actor, Jason Momoa, and Mera herself, Amber Heard, who both shared wrap photos to celebrate the last seven months together. Filming on the latest DC Extended Universe project officially kicked off back in May in Australia and continued up until this morning.

Momoa posted a goofy photo of him and Heard, taking a moment to thank the star for her work as Mera, and Australia for allowing the production to film there.

Heard celebrated the seven months -- including pre-production -- she got to spend working with Momoa.

The film, which will mark Aquaman's first solo outing on the big screen, has been described as "Star Wars underwater," with Wan promising that fans can expect a “swashbuckling action-adventure, sort of high seas adventure story."
