Heath Ledger personifies the Joker in "The Dark Knight", characterised as a psychopathic, mass-serial killer, and schizophrenic clown devoid of empathy. Operating as a criminal mastermind and fomenter of chaos, his objective is to evaluate how far Batman will stretch to preserve Gotham City from plunging into anarchy and turmoil. His erratic and malevolent disposition renders him a frightening adversary, with Ledger's performance acclaimed as one of the most iconic and memorable portrayals of a villain in cinematic history.
