Yesterday I came upon an idea, so I thought I might share it. Keep in mind this is a theory, so if it is stupid or not, is up to you. Do you remember William Fichtner playing the bank manager in The Dark Knight, well what if he was Roman Sionis. I have heard several people say Nolan was going to put Black Mask in The Dark Knight, but didn't. But, maybe they did. It would make sense that Nolan hasn't said anything, simply because he is already cast.
I looked back at the conversation he had with the Joker. William asked the Joker if he knew who he was stealing from. I know he meant the mob, but what if part of it was his? Before Joker left William he said,"What ever doesn't kill you makes you stranger." Imagine if that sentence finally made him crack?
They never said the bank managers name, so there is no way you can say that's wrong. There is also something else that was brought to my attention. Many people are saying that Talia Al Ghul is not in The Dark Knight Rises. Well, all Nolan said is that Cottilard would "appear" Maranda Tate. Also, why would Nolan cast Ra's Al Ghul entire family, for no reason? Ra's also stated in Batman Begins that, "We have invaded there infrastructure." Which could mean his daughter is working at Wayne Enterprise.
Or, we could have Bane and/or Selina Kyle have deep connections with Ra's. Possibly Bane killed Ra's wife? Well, who knows! Also, let's talk Bane's venom. To be honest, Bane's venom could be in the Nolan verse. Let's be honest guys, alot of the things Batman has is really advanced. So, I'm sure Nolan could do something. Personally, I would like to see Scarecrow make that venom, but that's just me.
Thank you, and please comment.
