So where would be a good spot in the film for Batman to announce "I have one rule." I mean, it just doesn't seem like something he'd say to the bad-guys (using the bat-voice.) Although I suppose he could be talking to Gordon or something. I wonder if there is more to the line... like... Gordon: He's a madman. He has to be stopped ... any way you can. Batman: I have one rule. I'm bringing him in by the book. What do you guys think? I hope it's not something like "I have one rule. I never kill. No matter what. Killing is wrong. It's the difference between justice and revenge!"
