I got a great idea for the next full-on Batman movie. How about Joker's girlfriend comes back for revenge? The Bat is tormented because he doesn't want to beat up a girl so he gets kicked in the Bat nuts a whole bunch. It's awesome I know. This continues until the end of the film where Batman finally has a chance to finish her, but as he pauses mid-punch, a voice off screen goes "Hello Bats!" and then it shows the Joker from the back looking over the scene, freeze frame, then out Where's my $100 mil for this brilliant idea?
