BATMAN 3 will be centered around a killer mystery, ala LONG HALLOWEEN and DARK VICTORY. A killer is taking out different bad cops, leaving pinned riddles and clues on them. The thing is, the clues and riddles are written on Harvey Dent's old case files about the mob. In reality, the whole thing's just a mind game set up by the Riddler, but it takes the film a long time to get to that revelation.
Riddler is a very hard character to write for, and this fits well indeed. It’s what I’d like them to do as well. The Riddler’s intelligence, sleuthing and possible connections make him find out something that very few know, that
- and it is wracking everyone’s brain – Batman included.
Riddler doesn’t kill, or doesn’t like to, so you could have him as a mastermind of the whole operation. He still condones the killings, though. He’s adding the riddles to the bodies for his game.
It is keeping alive the character of Dent in a way, and I like that. I’d make The Riddler true to form, but a little harder edged. I’d throw in some bizarre death traps in the Jigsaw vein, and flesh out the excessive compulsive side.
You can also have it that Riddler discovers Batman’s identity, ala the plot point from TDK. When it all hits the fan, the last bargaining chip could be Wayne’s identity. Riddler’s gizmos hijack Gotham Cable News and project an image of Batman on a screen, slowly being revealed pixel by pixel.
