i wasn't around for Begins,or any of the hype/speculation with it,but certainly was for TDK and Rises! things i distinctly remember with some nostalgia:
-rumors that the Joker WOULDN'T be in TDK. that the card at the end of BB meant nothing,just a little teaser idea for some later movies.
-pics of Heath,on set, SANS makeup but with the green hair and full suit.
- people flipping after pics of Cillian Murphy on set in a parking garage leaked.
- the discussions/wars over whether the new Batsuit was good or crap.
- the speculation of whether Harvey would or wouldn't become Two-Face in TDK. because,you know,he was ONLY listed as Harvey Dent on the call sheets!
- when the 1st commercial that showed the sonar eyepieces in action premiered...boy,did THAT cause an uproar!
-the 3rd film would open with the Joker on trial, Dent as the prosecution,and him getting scarred during the trial,leading to Two-Face as the main villain of Batman 3.
- Philiph Seymour Hoffman as the Penguin in Batman 3!
- WB wanting Angelina Jolie as Catwoman and Johnny Depp as the Riddler in the 3rd film.
- Tom Hardy was playing Harvey Bullock, Killer Croc,Clayface, or Dr. Hugo Strange, depending on what week it was!
- the 3rd film would mostly take place in New Orleans, with the main love interest being Julie Madison,and actress,and the villain Clayface,a scarred actor who disguised himself with makeup and theatrics while being a serial killer.
Lt. Sarah Essen would be Gordon's partner in the 3rd film.
...LOTS of wild rumors floating about!! but,you know,that was part of the fun! because as much as you thought you knew, the "leaked info" would then take a wild turn into something else.
