According to sources, there are some new juicy Batman 3 rumors to going around. Here are some of them:
1. The plot is already in place, and David Goyer and Jonah Nolan may have already completed their first draft of the screenplay.
2. The source claims that The Riddler will be the main villain, and that Arkham Asylum will feature heavily in the film. Classic Batman villains such as The Penguin and Mr. Freeze (in his Dr. Fries incarnation) could make cameos.
3. The role of Barbra Gordon will be “beefed up”, and Dick Grayson may appear, but not as Robin.
4. Commissioner Gordon may “name drop” the Superman Universe, mentioning Metropolis and Lex Luthor. Remember, Christopher Nolan has been hired to “mentor” a new Superman franchise.
Currently, these are rumors as of now and have not been confirmed by the studio.
