Batman 5; What Could Have Been

I know what your thinking, "Not another ing Batman Topic", but come on, there seems to be a good portion of Batfans on this board, however this isn't a TDK, or TDKR thread, or even a Batman89 thread, this is for what was supposed to be the 5th Batman film, slated for a 1999 release, and to be called Batman Triumphant, sure there have been many rumors and speculation, but some things do keep on croping up, so yea, lets go through them, cause I'm guessing this may interest more people on here than just myself.

So yea, after B&R looked very promising (and at the start, it did, check out the teaser, looks amazing) Warner started lookng towards a fifth, which would bring it back to a darker tone, the constant thing that does stay is that the villians would have been Man-Bat and Scarecrow, with, the Joker returning via a fear dream from Scarecrow, with Harley as his wife, infact, its said that Nicholson had actually been contacted and agreed to it, actually its said that he had lobbied to be in another Batfilm for years.
Anyway, thats kinda what is kinda set in stone, or atleast was at the time, but it was to get darker, Batgirl was to get killed off in the first 15 pages of the script, Robin was now Nightwing, and Batman was semi-retired. However, with Man-Bat terrorising the city, Batman was to come back and help Nightwing defeat Man-Bat. I also read that Jervis Tetch was set to appear too, however it's unkown if he was to become Mad-Hatter or not, but to me, that would have been insane.

Below is what was a prototype for the new Batlogo, well, Film Logo;



Now, sure, this is all rumor, however mostly all include this info, I know it doesn't make this true, but to me, it sounds plausable, and tbh, quite great, and would have shot some life into the franchise again, and hopefully sent it in to a state where it was unstoppable, like the Bond franchise, this way, it would have made better use of villians, and really kept alot of people interested.
