Clarified already DN GET WITH THE TIMES.
I agree wholeheartedly with Freeze, as I said before, because he's not really cut-and-dry (no pun intended) as a character. But to be fair, guys, don't base the Riddler off of Jim Carrey's freakish performance. He has something like super OCD, and he physically cannot NOT leave clues. He doesn't really want to leave clues, but he has to. Also, he might be a little similar to the Joker on the outside, but he's actually a 'schemer' that Joker was talking about in the movie. He has elaborate death traps and big plans, and while the Joker had plans too, these are more plans for crimes, instead of plans of instilling chaos in Gotham. Nolan could make something very different from the Joker with the Riddler I think!
Also Bazooka, Bane is a really interesting character too. He kind of had the past of Edmond from The Count of Monte Cristo, I dunno if you know it. He spent a long time in a jail, paying out his father's debt, and during that time he got a real classical education. He's actually really really smart, like, he figured out Batman's identity in one day and, instead of just taking him on himself, he freed everyone from Arkham and after Batman tired himself out catching everybody, Bane fought Batman and broke his back. He's also on this drug called Venom, which makes him super-strong. He needs to have it every 12-hours, though, or else he goes into this extreme withdrawals.
I read too many articles on wikipedia...
