Even though filming started two weeks ago in Australia, Warner Bros.‘Aquamanis still filling out its cast, with newcomer Otis Dhanji recently coming aboard to play the youngArthur Curry. Today we have word that another important role has been filled, withPower Rangersstar Ludi Lin joining as Murk. In the DC Comics, Murk was the leader of the Atlantis army known as the Men-of-War, who served as the underwater kingdom’s first line of defense.

Deadlinereports that this marks the first major role for Ludi Lin sincePower Rangersdebuted in March, which opened big with $40.3 million, but dropped off quickly, ending its domestic run with $84.8 million and $135.5 million worldwide, from a $100 million budget. It isn’t clear if Ludi Lin has already started filming his role in thisAquaman movie yet, or how large his role in this superhero adventure may be. In the comics, Murk served Orm the Ocean Master, played by Patrick Wilson in this movie, andAquamanhimself, so we’ll have to wait and see how his character will be portrayed.

In the DC Comics, Murk disobeyed Atlantean law and showed his loyalty toOrm the Ocean Master, who he believed to be the true leader of Atlantis. He convinced both Tula and Swatt to join him on a mission to free Orm from Belle Reve, but while they were gone, Atlantis was attacked by Scavenger and the Dead King. The character is relatively new in the pantheon of DC Comics characters, created by Geoff Johns and Paul Pelletier, making his debut inAquamanVol. 7 #17, which debuted in April 2013. Whether or not any of these stories will be used in theAquamanmovie remains to be seen.

Ludi Lin joins a cast that also includes Jason Momoa as the title character, Amber Heard asMera, Willem Dafoe as Nuidis Vulko, Nicole Kidman as Atlanna, Yahya Abdul-Mateen II as the villain Black Manta, Temuera Morrison as Bob Curry and Dolph Lundgren as King Nereus. It isn’t known how many other characters have yet to be cast, as production continues, but director James Wan has previously confirmed that the DC Comics character Aqualad will not be a part of this movie. James Wan directs from a script by Will Beall, based on a story he devised with Geoff Johns.
