Villains are arguably the most important part of any Batman narrative. They’re famously kooky, wise-cracking, and nasty and occupy a core part of what makes any Batman media so enjoyable. The performance, costuming, and writing are tantamount to making a good Batman villain. Luckily, some live-action films have managed to get it right.
Heath Ledger's Joker is the most iconic live-action portrayal of a Batman villain. The Dark Knight may have defined what a dark superhero movie meant, but Ledger defined The Dark Knight. Chaotic, cold, and captivating, Ledger’s Joker managed to silence the audience when he first made his appearance on the silver screen.
The way Ledger delivered his lines helped make the Joker feel more real and well-rounded. His look also became iconic, as his costume was a wonderful homage to the comics. Ledger received a posthumous Oscar in 2009 for his portrayal, which has been regarded as the best Joker performance of all time.
