Describing his preparation for the role of the joker, Heath Ledger said “I sat around in a hotel room in London for about a month, locked myself away, formed a little diary.”
According to his father, Kim Ledger, Heath liked to dive into his characters. So the hotel part wasn’t out of character (no pun intended). However, with the diary, Kim said that he really “stepped it up a notch.”
Such dedication to a role really makes me appreciate the art of acting. What Health did is a clear example of hard work and dedication to your passion. As a result, his portrayal of the joker was incredible.
