More of The Dark Knight (2008)

Also in the film The Dark Knight (2008), fans will remember the scene in which The Joker (Heath Ledger) dressed up as a nurse to infiltrate the hospital and blow it up. When The Joker initially presses the remote button a small explosion happens. We see a look of confusion on the villain's face as he presses the remote several more times. Suddenly, the entire hospital blows up, but what most fans didn’t realize was that this scene was also improvised by Heath. When the explosives stalled, the actor started playing around with the bomb remote in classic Joker fashion, which gave us the scene of him standing in confusion.
