Most people know that the role of The Joker was a big factor in Heath Ledger’s untimely death. But it’s shocking just what he did to immerse himself in the character. Ledger locked himself in his hotel room in London for more than a month to be alone with his thoughts. He left behind a creepy diary that shows a window into his mind.
His father Kim Ledger said, “That was typical of Heath on any movie. He would certainly immerse himself in the upcoming character. I think this was just a whole new level.”
