1) Heath Ledger in The Dark Knight
Batman Begins ends with one of the most exciting teases for a sequel ever: Lieutenant Jim Gordon (Gary Oldman) shows Batman (Christian Bale) a playing card recovered from a crime scene. It’s a joker. Who could play the iconic villain in the sequel? Who could fill Nicholson’s shoes?
Director Christopher Nolan chose Heath Ledger, sparking immediate backlash. The young Australian heartthrob, then best known for Brokeback Mountain, 10 Things I Hate About You, and A Knight’s Tale, seemed a far cry from what most Batman fans had in mind.
Ledger’s take on the character would go on to become the stuff of legend. His Joker is not given a definitive backstory (no vat of acid here), making him even more terrifying. An anarchic figure who takes sadistic glee at throwing Gotham City into chaos and commits acts of terrorism to upend social order, this Joker makes for a formidable opponent. He’s the id to Batman’s ego, the yin to the yang, an unstoppable force clashing against an immovable object.
Ledger took inspiration from Malcolm McDowell’s portrayal of Alex DeLarge in A Clockwork Orange. He was also inspired by musicians including Sid Vicious, Iggy Pop, and Tom Waits, giving this version of the Joker a bit of a rock star vibe.
He tragically died of an accidental prescription medication overdose in January 2008, six months before The Dark Knight was released. While some claim that immersing himself in the role drove Ledger over the edge, his friends and family deny this, and Ledger was already working on his next film, The Imaginarium of Doctor Parnassus. Ledger was awarded a posthumous Best Supporting Actor Oscar for his performance in The Dark Knight.
