“Game of Thrones” star Jason Momoa may be on the big screen in 2015, as it is rumored he will play supervillian Doomsday in the highly anticipated “Man of Steel” sequel. The as-yet-untitled Batman-vs.-Superman film will be directed by Zack Snyder, who also directed “Man of Steel” and “300.”

Doomsday is best known as the character who killed Superman, and was originally known as “The Ultimate.”

Momoa seems well-qualified to play the villainous fighter: In 2011, he played the title role in “Conan the Barbarian” as a warrior who seeks revenge on an evil warlord, and on the hit HBO series “Game of Thrones,” he stars as Khal Drogo, a warlord and feared warrior.

It remains to be seen if Batman and Superman fans will be pleased with Momoa being cast in the action film. Back in August, when Warner Bros. announced Ben Affleck would replace Christian Bale as Batman, many fans were quite unhappy.

“We knew we needed an extraordinary actor to take on one of DC Comics’ most enduringly popular superheroes, and Ben Affleck certainly fits that bill and then some,” said Warner Bros. president Greg Silverman in a statement. “Ben provides an interesting counterbalance to Henry [Cavill]’s Superman. He has the acting chops to create a layered portrayal of a man who is older and wiser than Clark Kent and bears the scars of a seasoned crime fighter, but retains the charm that the world sees in billionaire Bruce Wayne,” director Snyder said.

But Batman fans took to Twitter to complain, and “#BetterBatmanThanBenAffleck” quickly became a trending topic, with memes and hilarious tweets about who Warner Bros. could have picked for the coveted role instead of the former "Daredevil" star.
