As of 2013, Warner discussed the idea of opening up the world of DC to film thanks to the likes of the Avengers. On the discussion was more Superman, Batman, Batman vs. Superman, Cyborg and Wonder Woman movies.
Batman vs. Superman started life after Zack Snyder was announced to be directing a sequel to Man of Steel, written by David S. Goyer. Nolan returned as an adviser.
Inspiration for the movie came from The Dark Knight Returns, though not completely based on it. The basis is that it's an older Batman that has been doing the job of Batman for 20 years and sees Superman as a threat. At the time of writing this article, Batman v Superman has earned over 500 million at the box office,
While not directly part of the Batman mythos, but sharing common villains, Suicide Squad nears it's release in August. It's written and directed by David Ayer, who describes it as "The Dirty Dozen, but with supervillains".
More news forthcoming as the time allows, but Ben Affleck will be returning for his 3 picture deal in a Zack Snyder directed Justice League film, featuring the cameo characters from the Batman vs. Superman movie. It'll be written by David S. Goyer.
Finally, it was revealed this week that Ben Affleck is working on his final movie with DC. He is writing a script with Geoff Johns. Affleck stated the graffitied Robin suit will be explored fully and we'll also be finding out who was in that suit when they died. Zack Snyder will also be directing this movie.
