We all knew Ledger kept a journal before and during filming of TDK to refine his performance as the Joker. But we never saw it until now. In the documentary Too Young to Die, his father shows this diary to the camera and talks briefly about the hospital scene. (You can also see Ledger's Oscar in the background.) So fascinating. I know Ledger took some cues from A Clockwork Orange, but the level of notes and influences pasted in the journal are so detailed. Also like the anecdote that Heath's siblings had him dress up a nurse when he was a kid and noticed how funny he looked in it.
