Per the report, she'll be lending her voice to the character of Karathen, a folkloric sea creature that aids Arthur Curry (Jason Momoa) in his quest to bring peace to Atlantis and the surface world. It's the perfect role for Andrews, 83, whose lofty and musical voice has been entrancing audiences for decades.
Aquaman will open two days after Mary Poppins Returns, a sequel to the 1964 Disney classic that starred Andrews in the titular role. Dick Van Dyke, who starred in the original, will return for the follow-up, but Andrews turned down a chance to make a cameo appearance in the Rob Marshall-directed film. Marshall explained to EW that Andrews didn't want to take the spotlight away from Emily Blunt, who is taking on the persona of the magical British nanny.
Aquaman splashes into theaters Dec. 21. Amber Heard (Mera), Nicole Kidman (Queen Atlanna), Patrick Wilson (Ocean Master), Dolph Lundgren (King Nereus), Willem Dafoe (Nuidis Vulko), and Yahya Abdul-Mateen II (Black Manta) are also a part of the movie's ensemble cast.
