Another day, another Man of Steel rumour. It seems this movie has no boundaries when it comes to cast and characters. Now it seems Game Of Thrones‘ Jason Momoa (a.k.a. the fearsome Khal Drogo) is in talks to star in Zack Snyder’s Man Of Steel 2. The Hollywood Reporter has reported that Momoa may be negotiating to play the role of the Martian Manhunter or possibly Doomsday. Given that the film has yet to have a title, is it silly to assume that it might actually be a Justice League movie and not a Man of Steel sequel?
