Heath Joker is incredibly and just amazing.....I think everybody just about mentioned everything he did already. I love when he escapes from precinct with his goons in the cop cars and he just sticks his head out the window and takes some air with the silent type music (nice camera work too)....It didn't do much for me in the trailer but big scene where Gotham and batman world just took a turn for the worse..the Joker is just taking some cool air after a perfect plan....
And anytime the joker is on screen this eerie music comes on, it sounds like a bunch of alarms. It starts off low then as the scene progress it gets louder!! and thats when you know something is about to happen and the drums come on and everything just happens...man that is awesome I think its called "why so serious" on the soundtrack....
I love the build up to the party as soon the elevator door opens the hard drums come and The joker says "We made it"...heath ledger was legendary!!
