It appears that Nicole Kidman has a few personal reasons for making her return to the superhero genre in Aquaman.

At the end of January, reports began to surface from outlets like The Hollywood Reporter that actress, Nicole Kidman would be joining James Wan’s Aquaman as Queen Atlanna.

In a recent interview with Entertainment Weekly, Kidman finally spoke publicly about joining the project. She also revealed that it was her relationship with Wan and his pitch for the character that drew her to the role:

“The reason why I love [Aquaman] is James Wan is an Australian, and I’ve followed his career since he started. He’s a really good friend of mine, and he offered to let me play Queen Atlanna. As soon as he said I could wear mother-of-pearl and be a mermaid warrior, I said I’m done. Please. If there is one thing I have to do in my life, I have to be that. [Laughs] Because you’ve got to have some fun.”

Those are pretty good reasons for wanting to sign on to the film. Of course, Kidman is no stranger to the world of superhero movies. She played Dr. Chase Meridian, the love interest of Bruce Wayne, in Joel Schumacher’s Batman Forever (1995).

Comic fans undoubtedly know Queen Atlanna as the mother of Arthur Curry (Aquaman), who escaped Atlantis and gave birth to the hero after falling in love with a lighthouse keeper.

She later became queen of Atlantis beginning with DC Comics’ post-Crisis continuity, and has since become synonymous with the role. She most recently appeared in The New 52 continuity as the former ruler of Atlantis.

With her casting, Kidman will join the likes of Jason Mamoa, Patrick Wilson, Amber Heard, Willem Dafoe, Yahya Abdul-Mateen II, and Temuera Morrison.

Aquaman is slated for release on December 21, 2018.
