The latest name to surface in regards to a role in Batman Vs. Superman is Jason Momoa.
There is no word what the role might be, but it's possible Jason Momoa could either be Doomsday or the Martian Manhunter (via THR).
Momoa is known for roles in Game of Thrones as well as the recent Conan reboot.
Momoa is said to be in negotiations for Batman Vs. Superman, and if he lands the role would join the recent cast addition of Gal Gadot as Wonder Woman.
Fans are noting the movie is looking more and more like a Justice League film as The Flash is said to appear as well, and if Momoa is indeed the Martian Manhunter - that looks to be the case.
Momoa would make a pretty cool Doomsday, though.
"Batman Vs Superman" has a July 17, 2015 release also starring Ben Affleck, Henry Cavill, Amy Adams, Laurence Fishburne and Diane Lane.
