The debate about who has the best Joker laugh has been reignited, but the correct answer is Mark Hamill. The Joker's laugh is an iconic and intrinsic part of the character, and every actor who takes on the role not only has to perform their own version, but invariably be compared to what's come before in the world of DC movies and TV shows.
With the release of the final The Dark Knight).
However, while each of these actors was great as the Joker, and all brought something unique not only to the role but to the laugh itself, it's Hamill's Joker who has the best laugh. The rest are all good-to-great, and Ledger's is definitely a close second, but there are a few reasons why Hamill has the best - and really, the definitive - Joker laugh. This goes with his incredible talents as a voice actor, meaning he was able to put more into the laugh than the other actors, who had to give a more physical performance as well. That's not to detract from what Hamill did in any way, but rather to highlight the fact that he needed to so embody the character through his voice, making the laugh even more important, and to his credit he ended up nailing it.
Hamill's Joker laugh is chilling, sinister, and downright creepy: exactly what you'd want from such a major villain. But at the same time, it's not the laugh of someone just trying to be evil, but someone who is genuinely amused and amusing. Hamill tapped into the comedy of the character better than anyone else, and that really shines through in his Joker laugh, while it also captures the Joker's insanity too.
What Hamill really understood about the Joker's laugh is that it couldn't just be one thing: it has to convey all of his different moods, with the the Joker through the laugh that really sets him apart from the rest.
