The Hollywood Reporter‘s Heat Vision Blog has heard from sources that Jason Momoa (“Game of Thrones”) is in negotiations to join the cast of Zack Snyder’s Batman vs. Superman movie in an undisclosed role.

Momoa first broke out playing the warlord Khal Drogo on HBO’s hit series “Game of Thrones” before being cast as Conan the Barbarian in the 2011 remake by Marcus Nispel. Most recently, Momoa could be seen fighting Sylvester Stallone in his action flick Bullet to the Head, and he’s also starring in David Hayter’s werewolf action movie Wolves.

THR offers a bit of conjecture about who Momoa may be playing, mentioning the rumors that the Kryptonian killing machine Doomsday may be one of the film’s primary villains, but another option they suggest is J’onn J’onzz AKA The Martin Manhunter (right), a shape-shifting telepathic alien that was one of the key members of the Justice League.

Considering that Batman and Wonder Woman are already confirmed for the sequel to Warner Bros.’ hit Man of Steel and The Flash has already been rumored, adding the Martian Manhunter certainly would seem like they were setting the movie up to be the long-delayed Justice League movie.

Nothing’s been confirmed by Warner Bros., but let us know what you think about Momoa playing one of those two iconic comic characters.
