I remember being 10, first seeing the trailer in the Warner Brothers store (remember those?). Prior to seeing the trailer I wasn't happy about the news that Batman had be recast again, but the trailer sold me on it being a good movie that dealt with more of a Bat-family dynamic. I got excited when I saw it and tried to hang around the store long enough for it to play again.
The use of Elfman's score on a Schumacher trailer can be really deceiving...
