Read these "Dark Knight" quotes to gain a deeper understanding of the popular motion picture. Joker unleashes havoc in the city of Gotham and tests the limits of Batman and district attorney Harvey Dent. Screenplay writers Jonathan Nolan, Christopher Nolan, David Goyer and Bob Kane wrote the script for the characters to give the audience the best "Dark Knight" quotes.

"I believe whatever doesn't kill you, simply makes you stranger." The Joker is disguised as Bozo when he starts talking to the Gotham National Bank Manager. After the bank manager questions the beliefs of criminals, The Joker removes the Bozo mask and chillingly delivers the last word "stranger." The Joker is a very strange, demented character, so the quote possibly relates to his past; the things that did not kill him made him stranger.

"Some men just want to watch the world burn." Alfred Pennyworth tells Bruce Wayne that some men cannot be bargained or reason with. Some men want to commit crime because they believe it is a good sport; they do not do it for money, logic or fame. Alfred tries to explain that The Joker thinks crime is a good sport in this "Dark Knight" quote.

"You see, in their last moments, people show you who they really are." The Joker tells the deputy that he likes to use knifes instead of guns, because guns kill quickly; knifes make the torture process longer. He says he knows friends of the deputy more than anyone, and inquires if the deputy wants to know which ones were cowards.

"He's a silent guardian, a watchful protector; a dark knight." Batman runs away from a scene, and the son of James Gordan questions about it. James Gordan says, "Because he's the hero Gotham deserves, but not the one it needs right now. So we'll hunt him because he can take it. Because he's not our hero." This is one of the "Dark Knight" quotes that best depicts the image of Batman; dark, watchful and misunderstood.

"Why so serious?" The Joker was the source of the most popular "Dark Knight" quotes: "Why so serious?" With a blade inside Gambol's mouth, The Joker tells the story of his scars. The catchphrase "Why so serious?" was said by his father before he carved a "smile" on The Joker's face.
