1. Bruce Wayne aka BATMAN
After his performance in Krrish, he is the only Superhero in Bollywood that you can ever image. His resemblance with Christian Bale is secondary.
2. Lucius Fox
No competition here. It's the legend, soft spoken and intellectual.
3. Alfred Pennyworth
He is tremendous at acting as a supporter and guardian. What else do you want?
4. Commissioner Gordon
A disciplined Cop required for the Show, who remains reserved too at times
The best person for this job will be a low grade stingy thief and we have found one in recent times
He is very dynamic in the kinds of roles he takes up and excels most of the times(if not always). This supernatural role seems fit for him and it would be interesting to see him in such a role, moving away from "romance" just a little bit.
7. Harvey Dent aka Two-Face:
One person who is consistent about his work but is also fickle minded
The obvious Villain who is capable enough to tame the hero, both Physically and Mentally
9. Rachel Dawes
She is the "girlfriend" (or the love) material
10. Miranda Tate
Sex appeal? Her. Period.
11. Selina Kyle aka Catwoman
"Jangli billi"...This term just made sense, even if its just a few years later.
12. Ra's Al Ghul
A strict Mentor committing all his knowledge to the subject
13. The Joker
Can you think of an actor with better potential for this role? I mean you do have to keep in mind that Heath Ledger won the Academy award for Best supporting actor in 2008 for this role.
