Heath Ledger is a very good actor. He is so involved in the performance that it is difficult to go on after each performance. The clown played by Heath Ledger is very classic. In order to play this role well, Heath Ledger locked himself in a hotel and repeatedly tried to figure out the clown's heart, constantly adjusted his external body animals to make his role more suitable for the clown's image, and repeatedly practiced licking his lips, smoothing his hair and speaking tone.
At first, Heath Ledger hoped to play Batman in Batman, but the director hoped that he could play the role of a clown and eventually become the most popular madman. In fact, Heath Ledger's acting career was not smooth. At first, he was unpopular. At that time, Heath Ledger wanted to play the clown in Batman, but the audience didn't buy it. There were so many comments on the Internet that some people even boycotted the whole movie because they didn't like him. He was deeply disturbed by these comments.
Heath Ledger resisted all the pressure, conquered the audience who didn't like him with his own performance, and proved his acting skills and strength. In order to better understand a character, Heath Ledger once locked himself in a motel room for 43 days, and completely internalized himself into his role in this isolated way. This process is painful and mentally harmful. Therefore, Heath Ledger always suffers from insomnia.
Heath Ledger is also very dedicated and selfless when acting. Fighting with Batman, he is also serious, just to present this real effect. On the other hand, Heath Ledger is so deeply involved in the play that he constructs himself in Batman's virtual story and space. It is precisely because of this way of working and investing that he usually needs to take drugs, and also because Heath Ledger died of an improper overdose.
