The Game of Thrones actor is in talks for a part in the Warner Bros. film.

According to The Hollywood Reporter, Jason Momoa might join the cast on the untitled Batman-Superman movies created by Warner Bros. and DC Entertainment. There are rumors that say that the actor might play the role of the villain Doomsday, a Kryptonian scientifically engineered into an intergalactic killing machine. In the comics, Doomsday killed Superman, which became a media event in 1992.

Still, there are sources that say that Momoa might also play the role of super-powered alien, Martian Manhunter who is trapped on Earth.

Zack Snyder is directing the Man of Steel follow-up and until now the movie stars actors like Henry Cavill (Superman), Ben Affleck (Batman) and Gal Godot as Wonder Woman.

Jason Momoa played the role of the barbarian Khal Drogo in the first season of HBO’s Game of Thrones. He also played the role of Conan in 2011 in the movie Conan the Barbarian.
