The "Dark Knight" nickname was first applied to Batman in Batman #1 (1940), in a story written by Bill Finger.
The Dark Knight was filmed primarily in Chicago, as well as in several other locations in the United States, the United Kingdom, and Hong Kong.
Both the civilians and the prisoners refuse to kill each other, while Batman apprehends the Joker after a brief fight.
Before the police arrive to take the Joker into custody, he gloats that Gotham's citizens will lose hope once Dent's rampage becomes public knowledge.
Before he can flip for the boy, Batman, who was wearing body armor, tackles Dent off the building to his death.
Knowing the Joker would win if people found out the truth, Batman persuades Gordon to hold him responsible for the killing spree to preserve Dent's heroic image.
The Joker escapes with Lau, whom he later kills along with the Chechen.
The Joker threatens to keep killing people unless Batman reveals his identity, and starts by murdering Police Commissioner Gillian B. The Joker also tries to kill Mayor Anthony Garcia, but Gordon sacrifices himself to stop the assassination. Dent is taken into protective custody, but the Joker appears and attacks the convoy.
Batman comes to Dent's rescue and Gordon, who faked his death, apprehends the Joker, securing a promotion to Commissioner.
A co-production of the United States and the United Kingdom, The Dark Knight was released on July 16, 2008 in Australia, on July 18, 2008, in North America, and on July 25, 2008, in the United Kingdom.
