Reddit user u2aerofan discovered the video online and posted it to the Batman subreddit.

In a 2007 interview with Empire, Heath Ledger described how he prepared to play the iconic character and mentioned a diary that he used in the process:

It's a combination of reading all the comic books I could that were relevant to the script and then just closing my eyes and meditating on it. I sat around in a hotel room in London for about a month, locked myself away, formed a little diary and experimented with voices — it was important to try to find a somewhat iconic voice and laugh. I ended up landing more in the realm of a psychopath — someone with very little to no conscience towards his acts. He's just an absolute sociopath, a cold-blooded, mass-murdering clown.


“The hospital scene is interesting because when he was a kid, his sister Kate liked to dress him up as a nurse," Ledger said. "He looked pretty funny like that. He looked pretty funny in the film, too.”

The Joker: You know. I don't want there to be any hard feelings between us, Harvey. When you and, uh...

Harvey Dent: Rachel!

The Joker: Rachel were being abducted. I was sitting in Gordon's cage. Now, I didn't rig those charges.

Harvey Dent: Your men. Your plan.

The Joker: Do I really look like a guy with a plan? You know what I am? I'm a dog chasing cars. I wouldn't know what to do with one if I caught it! You know, I just... do things.
