Actor Jason Momoa is in talks to join the cast of the Man Of Steel sequel, according to a U.S. report.

It's unclear who the Conan the Barbarian star will portray, but reports have indicated he'll suit up as Doomsday, Superman's ultimate foe.

However, according to The Hollywood Reporter, if director Zack Snyder decides to fill the movie with Justice League characters, Momoa could portray the Martian Manhunter, an alien with super powers trapped on earth.

Henry Cavill will reprise his role as Superman in the sequel, while Ben Affleck has signed on to play Batman and Fast & Furious actress Gal Gadot will portray Wonder Woman in the highly-anticipated blockbuster, which is set to hit theatres in 2015.
