FUN FACT: This was improvised. The building was meant to explode and come down in one go and the crew had one take to get it right. When the explosions malfunctioned, Ledger reacted in character, and Nolan urged his crew to keep filming. By pure chance, it resulted in one of the greatest moments in the movie, and a moment that perfectly showcased Joker's archaic nature and Ledger's sheer talent.
In the scene where the Joker crashes the Dent fundraiser, Caine had a line right after the elevator opens. When Ledger stepped out, Caine forgot his lines because it was his first time seeing the Joker in character and in costume. Awesome!
Quote, the joker, dark knight, batman, quotes, laugh “I’ll tell you right now: You have to get fed up with being average. Period. Start STANDING OUT TODAY: Ordinary people go about their daily business, day in, day out with such routine that if anybody was to change anything, they would FREAK the fuck OUT. They use the phrase “same shit different day” quite often when asked how they are but then do nothing to change it.
