Jason Momoa is in talks to join the cast of Batman-Superman, the Man of Steel sequel, according to Hollywood Reporter.  Momoa has lots of geek cred from Stargate: Atlantis, his stint as Khal Drogo in Game of Thrones, and less desirably in Conan the Barbarian (see "'Conan' Actor Chosen"). 

The character Momoa will play has not been revealed; THR speculated that he could play either Doomsday or Martian Manhunter.

Momoa will join Henry Cavill, Ben Affleck, and most recently Gal Gadot (see "Wonder Woman Cast for 'Batman vs. Superman'") in the cast.
