Batman’s standalone film is being worked on currently by Ben Affleck and Geoff Johns (Mastermind of the DC Universe currently). The film is essentially in the writing process, and things are obviously being planned out.
The first rumors that splashed the internet was that Jason Todd (the second Robin, also known for being the one that was ‘killed’ by The Joker) would be the villain, also known as Red Hood. Sources are now indicating that this is NOT the case, but something else entirely.
What makes this believable? Well, Warner Bros did just throw the kitchen sink with their latest film, Batman v Superman: Dawn of Justice. So, this new update, sounds a TAD more credible. The latest rumor has Batman going against quite a few villains from the Rogue Gallery, enough to attract fans of all flavors. A bold move by WB, DC, Affleck and Johns.
