20 Mind-Blowing Facts About The Dark Knight Trilogy

12. The Joker Scared Michael Caine Into Forgetting His Lines

The first time Michael Caine saw Heath Ledger's take on The Joker was in the penthouse scene which featured the Clown Prince of Crime throwing Rachel Dawes from the building. The legendary British actor has since revealed that he was so taken aback by the sight of the actor (who was fully in character at the time), that he forget his line when Joker entered. It's really no wonder that Caine was so freaked out by Ledger's take on the villain. After all, some of The Joker's more unusual and creepy mannerisms included Ledger sucking at his cheeks and licking his lips. These initially came as a result of the actor's discomfort with the scar make-up, but it spooked Nolan so much (meaning that Caine wasn't the only one left somewhat unsettled by his performance), that he had Ledger include it as a character idiosyncrasy.
