But you never thought that the villains cannot be neither The Riddler,neither Catwoman????
Don´t be so sure that they will be in the movie.
Consider other possibilities too.
You already stopped to think that all these rumors about both are false?
Don´t believe in everything you read around.
Oh, I should clarify. I think the villain(s) could be anyone. I'd be happy with Riddler or Catwoman, but I agree not to take anything is gospel until there's confirmation or at least a very reliable source. The point of the "no main villain" theory is to speculate why there hasn't been a casting announcement.
