If you've been keeping up to date with the ever-growing cast list for Aquaman, you'll know that Michael Beach has been linked with the movie for the last couple of months. Intriguingly, the site claims that he's set to play a character named Jesse Kane, who Deadline describes as "part of a group of high-seas hijackers who has a fateful interaction with Aquaman".
This won't be the first time that Beach and Mamoa have co-starred together, as they both appeared on the hit show Stargate Atlantis.
Those still not familiar with Beach can look to James Cameron's Abyss and The 100, which airs on The CW.
In any case, Beach will be joining Jason Momoa who plays the titular role, Amber Head as his Queen Mera, Nicole Kidman, Willem Dafoe, Patrick Wilson, Dolph Lundgren, Ludi Lin, Temuera Morrison, and Abdul-Mateen II.
Aquaman is scheduled for release on December 21, 2018.
