Your sentiments are shared. Man, if only Scene 24 wasn't left on the cutting room floor...
Well, there's a few interesting things to note from the trailer. A few more Minifigures cameos among MetalBeard's crew, as seen at 1:07. Dumbledore apparently will also be making a cameo appearance in Cloud Cuckoo Land, as seen at 1:09. Uni-Kitty's voice is less obnoxious in this trailer, as opposed to that other TV spot. MORGAN FREEMAN READS THE PHONEBOOK AND IMITATES BATMAN. Also, apparently, Octan Tower is microscale. If you freeze-frame at the end when Virtuvius is imitating Batman, Batman's mask pops off and you see Bruce Wayne's face underneath. Also, there's a ton of funny background events in this trailer. There's one clip where Batman is interrogating some guy, and another where some girl dumps a cup of water on a guy and messes up his hair. And, let's see, what else...
Oh, yeah. 0:57. I'll just leave it at that, because I can't put my reaction to 0:57 into words. You need to see it to believe it. And I'm not talking about Bad Cop/Good Cop.
