"The Demons End" - I figured they could make a trilogy out of Ra's and Batman going back to back canceling each other out w/ their intellects. Ra's could be out of the limelight for half the movie so that the other villians get their respective time to shine. But I think they've established Ra's as Bat's most dangerous enemy in the first flick. So I think he should always be there.
"I.n B.lackest N.ight" - I think Talia can come in on the second movie, have a love affair w Bruce, and the outcome can be the same as Son of the Demon. I think that would be a good representation of the theme of Batman throughout the course of time. Begins could represent the beginning, The Dark Knight could be the middle ground - Batman's coming of age, and IBN can represent the future(through batman's son).
"Son of the Morning" The movie could open up w villians coming out of the woodwork, and Batman could go throughout the whole movie questioning if this is all his fault. Then, he can drift into a darker path.
"Son's of Man" Batman and Superman.
But since none of these ****s'll ever make it (unless they accept my screenplay), I think I'll go w/ THE GODDAMN BATMAN. That would be so ballsy that it would sell for just that reason.
