Come with me if you want to live, Khaleesi

Looks like the Casting decision of Looking into Westeros was fruitful. Sarah Connor is now a Targaryen... (Last Sarah Connor was a Lannister... wait... If Cersei Lannister was Sarah Connor, does that Make John Connor Joffrey?)

All jokes aside, Emilia Clarke is now Sarah Connor and Old Man Ahnuld is the T-800... Well, the good news is that John Connor will not have my permission to die! No more Bane as Connor... WOOHOO!!

Besides this wouldn't be the first time Emilia Clarke has worked with a Conan...

Speaking of Conan and Game of Thrones people, Jason Momoa (Khal Drogo and the Other Conan) is likely to appear on the Battfleck movie... with Superman and Wonder Twig...

Who will he play? Remember that this movie is a set up to a Justice League Movie. He cannot be a pushover villain like Lex Luthor... Also, who'd dare to shave Khal Drogo's head to make him Lex Luthor. Doomsday could be an interesting choice, but I don't see it... Momoa's already typecast into Barbarian-esque roles, due to his physique... Now which DC Character could benefit from Momoa's "Exotic and Primitive" looks while being far too dangerous for Superman to handle alone?

Something more dangerous than Zod and Ra's al Ghul combined...

VANDAL SAVAGE... That's the only character I can think of. If the movie is going to be the set-up for JLA, having Savage rise to the point that Superman, Batman and Wonder Woman need to gather as many superbeings as possible to stop him is the only way... I mean the other threats to the DCU
would be aliens and we saw Ryan Reynolds beating Parallax on his own, we saw Superman stop the 3 Kryptonians... Darkseid, Starro, Mongul, etc. could be considered a bit too silly (and ripping off The Avengers' plot) to the non-comic book fans. Who else could they do?
Mister Mxyzptlk? Unless he's CGI and voiced by Gilbert Gottfried I don't want a Mister Mxyzptlk in the DCU movies... Besides there's no chance in Hell for that happening due to the Nolan "Realism" bull...
