9. Martian Manhunter - Jason Momoa
We've already seen
rumours that the Game Of Thrones hulking actor was set to be cast in Batman Vs Superman - though he has subsequently
denied any concrete casting, suggesting the rumour maybe no more than postulating based on how appropriate he is for the genre. Momoa's size is certainly one of his chief selling points: it would probably be foolish to suggest that he was cast as either Khal Drogo or Conan The Barbarian based solely on his acting ability - but then, suggesting he is no more than a muscle-bound costume-filler would be a disservice as well. The actor previously admitted that he auditioned for the role of Drax The Destroyer in Guardians Of The Galaxy, and he would bring the same appealing characteristics to Martian Manhunter. His presence is a major plus - he would tower over both Superman and Batman, which seems appropriate - and there is something chillingly other-worldly about his eyes that would work well.
