I finally got to see it!

   The Dark Knight...  I think Heath Ledger was amazing. His best role ever. But I agree with the voice changing of Christian Bale being annoyingly unnecessary. I understand he was trying to disguise his voice so people wouldn't figure out his true identity, but was it really necessary??? NO.  I think they should make another movie but not replace Ledger. They should have Charlize Theron or Angelina Jolie as Catwoman and someone cool to play Bane. WHY HAVEN'T THEY DEBUTED BANE!?!?!?!  >.<  Arnold should of played Bane...   ...not Mr. Freeze. BLAH! 

  Also, what about Holly (AKA Harlequin)?  Why wasn't she in The Dark Knight?  I think if by some creepy chance they replace Ledger, they should bring on Holly, and cast Brittany Murphy.

I heard rumors of another movie with possibly:  Johnny Depp as The Riddler, Angelina Jolie as Catwoman, and Phillip Seymor Hoffman as Penguin.

Oh!  What about Ron Perlman as Bane!?!??!?!!?!?  Yeah!!!!!   ^_^

EDIT: 

Bane appears in the live-action movie Batman and Robin (1997).

 They should have him as a main villian and played by someone cool. :
