In an interview, Heath Ledger said that the Joker was his favorite role and it’s very clear why. He was iconic in The Dark Knight, and I don’t think anyone can imagine that movie without him – or imagine that part played by any other actor. A lot of Heath went into that part, and there have been countless stories about how he was behind the scenes. But here are fifteen facts about his Joker that you probably don’t know
#1 Locked Up
To really get into the Joker’s head, Heath locked himself in a motel room for 43 days. This allowed him to feel isolated and alone with his thoughts and perfect the crazed Joker we all saw on screen.
#2 Like Clockwork
The gestures of the Joker were heavily influenced by Alex De Large, the main character of the 1971 movie A Clockwork Orange, played by Malcom McDowell
While the actions of the Joker were influenced by one actor, the appearance of the Joker was based on musician Sid Vicious.
#4 Tongue Tied
Heath Ledger had a natural habit of flicking his tongue, but he amped it up for the part of the Joker. It also helped with the way the Joker sounded, as the voice he does requires him to have a moist mouth.
#5 Age Doesn’t Matter
Heath Ledger is the youngest actor to have played The Joker, but it’s clear he held his own against bigger, more famous actors who have taken on the iconic role.
