Aquaman: Julie Andrews Has a Surprising, Secret Role in the Film

In addition to prominently featuring multiple members of the Atlantean Royal Family, Warner Bros.' Aquaman has also enlisted a member of Hollywood royalty for a previously undisclosed role in the film.

As reported by Entertainment Weekly, veteran actress and Oscar-winner Julie Andrews, perhaps best known for her starring roles in such classic films as Mary Poppins and The Sound of Music, has boarded DC's upcoming aquatic adventure.

Andrews will lend her lend her iconic voice to the mythical sea creature known as the Karathen, who is described as being a central figure in Aquaman's quest to unite Atlantis and the surface world.

"We wanted the Karathen to have the voice of a classic British actress, albeit somewhat digitally altered," said producer Peter Safran. "And when we found out Julie was interested and available and excited to do it casting her was a no-brainer."

Interestingly enough, Aquaman is set to go head-to-head at the box office with Disney's Mary Poppins Returns, a direct sequel to the original 1964 film, which starred Andrews as the titular character. Moreover, Mary Poppins Returns is also set to feature an underwater sequence.

Andrews was actually approached to make a cameo in the new Poppins film but ultimately declined, as she wants the audience's undivided attention to be on Emily Blunt's new interpretation of the classic character.

“Who knew that Aquaman would have the real Mary Poppins this Christmas?” Safran jokingly added.

Directed by James Wan, Aquaman stars Jason Momoa as Aquaman, Amber Heard as Mera, Patrick Wilson as Ocean Master, Willem Dafoe as Nuidis Vulko, Yahya Abdul-Mateen II as Black Manta, Temuera Morrison as Thomas Curry, Dolph Lundgren as Nereus, and Nicole Kidman as Queen Atlanna. The film opens on December 21.
