I am not certain how the story would go, but I am sure of who I would like to see cast in the movie.
Bruce Wayne - Christian Bale
Well There isn't much to say about this except, if it ain't broke don't fix it.
Older Bruce Wayne - James Brolin
I have seen many names tossed around for an older "Dark Knight Returns" style Bruce Wayne. My choice is James Brolin because not only do he and Christian Bale look a like, But James has delivered some powerful performances in his day.
Alfred Pennyworth - Michael Caine
Michael Caine is a fantastic actor that delivers the characterization that Alfred DESERVES.
James Gordon - Gary Oldman
If you have to be sold on Gary Oldman for anything you probably shouldn't be allowed to watch movies.
Selina Kyle - Eva Green
Eva is a fantastic French actress, with a knack for accents, and an intense presence.
She could bring a darkness and beauty to the role.
I think Catwoman Should be played as a Debutant, with some criminal hobbies that Bruce and batman both encounter.
She would be like the polar opposite of Bruce. Classy Debutant during the day, major heist puller at night.
Edward Nigma - Guy Pearce
Being one of the most versatile actors of our age,and taking such thrilling performances into account (Chris Nolan's Memento),
he could BECOME the Riddler, in a way that other actors just couldn't do.
I think The Riddler should be played like a throw back to Kevin Spacey in Seven.
Dick Grayson - Joseph Gordon-Levitt
I know he is a lot of peoples choice for The Riddler, and I also know that Nolan said he would never do a Robin.
I think he would be a great choice for Robin if they made him someone that follows Batman and helps him without his consent.
