The Joker played by Heath Ledger won him an Oscar. It will never be forgotten by cinema fans, ever. It is known as one of the darkest characters in movie history.
Nobody expected that the pretty boy from 10 Things I Hate About You could pull off such a demanding and taxing role, but the prep he put in really paid off.
Heath’s father, Kim, said in the documentary Too Young To Die:
“He pretty well locked himself up in a hotel room for weeks. He galvanised the upcoming character. That was typical of Heath. He would do that. He liked to dive into his characters, but this time he really took it up a notch.”
It was while he was hidden away that he developed tics, the deep voice and the famous sadistic laugh. He also began rolling his tongue around in a mannerism that he took to the screen.
Rumors have emerged online that The Joker’s distinctive voice was based on a 1979 TV interview with actor and musician Tom Waits.
Waits and Ledger both had roles in the 2009 movie The Imaginarium Of Doctor Parnassus. However, it’s not known whether the pair ever met.
During the interview, Waits’ speaking voice and mannerisms display an uncanny similarity to Ledger’s character in The Dark Knight.
