According to birthmoviesdeath.com, you might see your favourite villain in Ben Affleck's Batman film. Why? Because all of them will probably be in it. The source had the following to say:
"Many, if not most, members of Batman's rogue's gallery will be making appearances in the film. It's going to be crammed with Bat villains, which means that just about every major bad guy you've ever wanted to see in a movie will be in this movie." Devin Faraci of Birth Movies Death continues, stating that his sources have said "Affleck and Geoff Johns...want to make the definitive Batman film. They want to tell the ultimate Batman story, and to do so they're going to bring in all the big guns. They're going to have a big, sprawling Bat universe already in place".
This may come as a shock to most fans, who all have their own ideas about who the villain should be. I'm sure many thought The Joker considering Jared Leto will be making his debut in Suicide Squad this August.
