It’s been almost 9 years since Heath Ledger tragically died in his NYC apartment due to an accidental drug overdose, but new details about his life leading up to that day are still coming out.

Page Six reported this past week that Heath Ledger’s Manhattan apartment was somewhat of a shrine to The Joker. Ledger had just wrapped on shooting The Dark Knight a couple of months before his death.

According to Page Six’s sources, when police entered the home of Ledger after his overdose they found Batman comic books, literature on the Joker and clowns, small clown statues and recordings of Ledger practicing his oddly shifting Joker voice in high and low octaves.

“He was studying up on the origins of clowns and all of the previous Jokers like Jack Nicholson’s character and Cesar Romero’s, who was the first Joker on TV,” the source said.

“He was trying to make his role different from the roles of the other actors. He was even studying how to make his voice different from theirs,” the source added.

All of Ledger’s hard work and preparation turned into an Oscar winning Joker performance that people still talk about to this day.
