Yes, "Aquaman" is still casting! The DC superhero flick, which just started production, will open on December 21, 2018.
Deadline reports that Lin will play Murk, the leader of the Atlantis army known as the Men-of-War and a trusted ally of Aquaman (Jason Momoa). That means he'll be battling Orm Marius/Ocean Master (Patrick Wilson) and Black Manta (Yahya Abdul-Mateen II).
The actor tweeted that he's "stoked" to join Momoa in "Aquaman."
