Re: "The Dark Knight Rises" Review and Discussion Thread (spoilers)
I doubt they will be able to get all the actors (especially Michael Caine, Morgan Freeman and Gary Oldman) back unless Nolan produces/writes the script or they get a shitload of money thrown at them.
Caine has said in Empire magazine he would come back as Alfred even if it was a reboot.
