Joaquin Phoenix was fantastic, but no actor has been able to match the type of work Ledger performed for Christopher Nolan more than ten years ago. There have been actors before him and actors after his tragic death who have attempted to bring life to the character of the “Clown Prince of Crime.”
But what gave the Australian actor the ability to transform into such a menacing but mesmerising Joker?
Ledger made some substantial sacrifices that paid off and earned him recognition from critics and fans alike, in addition to some outstanding screenwriting and exceptional direction by one of the finest.
Six weeks of self-imposed isolation
Heath Ledger had to lock himself in a London hotel with a journal a few months before the filming of Batman in order to fully lose his mind while getting very little sleep to perfect his performance as The Joker. He experimented with his laughter, imagined voices, and talked to himself for weeks.
One of the most well-known facts regarding how Heath Ledger developed the persona of the “Agent of Chaos” is that he spent six weeks isolating himself from the outside world and living only in a hotel room. He also wrote the renowned “Joker” diary at this time, which detailed the actor’s thoughts. Also adhered inside the sheets were comic book pages and images of hyenas.
Dry mouth caused by an unnatural voice
When playing the Joker, Heath Ledger used an artificial accent and had a dry mouth in between takes despite having a very deep voice.
Because of this, he started licking his lips to keep them wet when he spoke, which greatly influenced the overall development of his character. It was also claimed later in the 2017 biopic I Am Heath Ledger that he did it to keep the prosthetic for his scar moist and adhered to his face.
Threw himself into walls to actually suffer injuries
Ledger requested Christian Bale to strike him as hard as possible during the interrogation sequence from the movie, but when the latter rejected, he started to fling himself against the walls to make the impact appear authentic.
He was throwing himself against the tiled walls within that set, which resulted in cracks and dents from him doing so. He gave all, claimed Bale in an interview with the Hollywood Reporter.
Extreme Sleepiness as a Result of Being The Joker
Even though Ledger had sleep issues for years, they grew worse when he was filming The Dark Knight as the Joker. Looper claims that the level of physical and emotional weariness he underwent for the part had a significant negative impact on his health.
Ledger discussed how he could only get a few hours of sleep each night before his mind would start racing with thoughts of the role in an interview during the film’s development. I probably slept 2 hours a night on average last week, he said. “I was unable to stop thinking. Although my body was worn out, my intellect was still active.
In the end, lack of sleep caused the actor to pass away unexpectedly before the film’s premiere from an accidental overdose of prescription sleeping pills, and the artist did not survive to witness his creations.
