1. Heath Ledger’s Joker Terrified Michael Caine

Michael Caine has been around for several of the Batman movies, and he’s been a staple of the franchise. He’d never seen anything like Heath Ledger’s version of The Joker however, and it scared him. Many believed that Jack Nicholson was the best Joker out there, but Michael Caine admitted that there was a clear difference between the two. Jack Nicholson’s character had a sense of humor, and his makeup was almost clown-like, whereas the portrayal that Heath Ledger offered the world was one of a true psychopath. The first time that Michael Caine saw Heath Ledger in full makeup was during the elevator scene. He seemed like such a scary and horrifying psychopath that Michael Caine forgot his lines. Maggie Gyllenhaal, who was playing Batman’s love interest couldn’t even look at Heath Ledger when he came in the room. He scared them both so badly that he proved that he could truly portray a psychopath.
