Footage of a diary that late actor Heath Ledger kept while portraying The Joker in 2008's The Dark Knight surfaced online on Thursday. The clip, according to The Hollywood Reporter, is from a German documentary series titled Too Young to Die, though it's dubbed in French.
The footage is narrated by Ledger's father, Kim, and shows a peek at the actor's detailed notes for the Oscar-winning performance, including photos of clowns, comic book panels and images of Malcolm McDowell's character Alex from A Clockwork Orange. Kim Ledger notes that it was typical for Ledger to thoroughly prepare for the role, but is heard calling the Joker diary "a whole new level."
THR says the documentary is scheduled to air on June 28. Here's the clip:
