Jason Momoa is in talks to star in the Man Of Steel sequel.
Henry is set to reprise his superhero role as Superman, while Ben is portraying Batman. Fast And Furious actress Gal Godot will play Wonder Woman in the as-yet-untitled movie.
While Jason's role is being kept under wraps, there is speculation that the 34-year-old could play Doomsday, a Kryptonian who has been scientifically engineered into a galactic killing machine, or the Martian Manhunter, a super-powered alien trapped on earth.
Jason, who played the barbarian leader Khal Drogo in the first season of hit TV show Game Of Thrones, last starred in Bullet To The Head opposite Sylvester Stallone.
He will next star in thriller Road To Paloma, which he is also directing, and werewolf action film Wolves, which will be written and directed by David Hayter.
