I'm going with my ideas for who I think the characters will be, based on what we've heard so far (which I know isn't much)
I'll start out with the obvious choices
Christian Bale as Bruce Wayne/Batman
He's done a fantastic job so far, nothing needs to be changed there.
Gary Oldman as Commissioner Gordon
In my opinion, the best portrayal of the character, next to the B:TAS version.
Morgan Freeman as Lucius Fox
He really brought the character to new heights, I love his portrayal and am glad to see him in the next film.
Tom Hardy as Black Mask
I'm in the minority (I think) that doesn't believe Hugo Strange will be in TDKR, I could be wrong thought. Not saying it's bad speculation because I think it'd be cool but I just don't see it happening. Black Mask fits in to the crime drama element of Nolan's Batman movies.
Rachel Weisz as Talia Al Ghul
The daughter of Ra's Al Ghul, this would wrap up all three movies and would fill the villain and love interest role. Plus, I really love Talia!
Anne Hathaway as Barbara Gordon/Oracle
I know, probably not gonna happen. But I saw an interview a while back with Nolan about the girl who appeared at the end of TDK and he acted really shady about it. In Begins, the Gordons had a baby and by TDKR they had two kids; they could do another age jump and have Gordon's daughter at age 20-22. I do think they would skip the paralysis part and have her do something like Lucius did in TDK. This seems to be the only plausible, non-corny sidekick, in my opinion.
James Gandolfini as Harvey Bullock
Definitely looks the part and I'd like to see some more of Gotham's finest from the comics enter Nolan's universe.
Rosario Dawson as Renee Montoya
After seeing her in the movie Unstoppable, I definitely think she would do a fantastic job with this role for Nolan's third movie.
Well, what do you think??
