Jason Momoa is in talks to join the upcoming 'Man of Steel' sequel.

The burly 'Game of Thrones' star is in negotiations for an unspecified role in the superhero blockbuster, which will see Henry Cavill reprise his role as Superman alongside Ben Affleck as Batman.

According to The Hollywood Reporter, Momoa may be in line to play the villainous Doomsday, who in the 'Superman' comic books 'killed' the heroic protagonist. The devious character is rumoured to be one of the main villains in the new film.

However, the actor may also be lined up to join a superhero team with Superman, Batman and the recently cast Wonder Woman - played by Gal Gadot - and could play the Martian Manhunter, an alien trapped on Earth.

Momoa is best known for his role as Khal Drogo in the first season of hit fantasy drama 'Game of Thrones' and recently starred in a remake of 'Conan the Barbarian', playing the titular character first made famous by Arnold Schwarzenegger.

The latest casting news comes after 'Fast & Furious' beauty Gadot was tapped to play heroine Wonder Woman, who will be brought to life on the big screen for the first time.

The untitled 'Man of Steel' sequel is being directed by Zack Snyder for a July 2015 release.
