The Dark Knight: Heath Ledger's "Joker Diary" revealed by his dad

What a way to start June 2013, by taking a peak at what is probably one of the "mysterious gems" ever reported about one of the biggest superhero films of our time and my personal favorite Batman movie - "The Dark Knight".

In what will be surprising and excellent news for fans of The Joker and Heath Ledger, The late and great Australian actor's dad just recently revealed his son's "Joker Diary" for the world to see, and it gives fans and viewers insight on what truly went inside the young actor's head to initiate the "development process" in creating his most famous role ever.

When director Christopher Nolan cast Heath Ledger as The Joker, nobody could have fathomed how excellent a performance the young Australian actor would give to the role, which would posthumously earn him an Academy Award nomination and win for "Best Supporting Actor". The 2008 sequel to "Batman Begins" would change the way we saw superhero films as a genre, and cemented the legacy of the Batman film franchise by becoming one of the most revered, if not THE BEST Batman film ever.

Known for his method acting approach, it was reported that Heath locked himself for weeks inside a hotel room to prepare for the role of "The Clown Prince Of Crime", and kept a "Joker Diary" to record his progress and get his mind into the character. The end result was an interpretation that was not only different from any other incarnation of Batman's archnemesis to date, but one truly chaotic and disturbing to boot.

Here's Heath Ledger's father, giving us a sneak peek at the "Joker Diary" his son pieced together. There's some French voice over, but that's hardly a problem when you see something like this.

Hopefully this comes out with a future re-release and update of "The Dark Knight Trilogy" collector's set. For more details and info, visit the source post at Batman-News and Uproxx.
