Game of Thrones' Jason Momoa is in negotiations to join Henry Cavill and Ben Affleck in Zack Snyder's Batman Vs. Superman. There's no solid intel on who he will exactly be playing in the film, but there's speculation that it could be the villain Doomsday or Martian Manhunter, who is part of the Justice League team. Of course, neither of these are confirmed, and he could be up for a completely different role. I could see him taking on either one of those, though.
Warner Bros. and Snyder are deep into casting the film, and they most recently brought on Gal Godot to play Wonder Woman. It will be interesting to see what other characters Snyder plans on packing into this movie, and who ends up being cast in those roles. What character would you like to see Momoa play in the movie?
