Nolan 's inspiration for the film was the Joker 's comic book debut in 1940 , the 1988 graphic novel The Killing Joke , and the 1996 series The Long Halloween , which retold Two-Face 's origin . The nickname `` the Dark Knight '' was first applied to Batman in Batman # 1 -LRB- 1940 -RRB- , 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 . Nolan used IMAX 70 mm film cameras to film some sequences , including the Joker 's first appearance in the film . The film is dedicated to the memory of Ledger , who died on January 22 , 2008 , some months after the completed filming and six months before the film 's release , from a toxic combination of prescription drugs , leading to intense attention from the press and movie-going public . Warner Bros. initially created a viral marketing campaign for The Dark Knight , developing promotional websites and trailers highlighting screenshots of Ledger as the Joker .   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 . Considered by film critics to be one of the best films of the 2000s and one of the best superhero films ever , the film received highly positive reviews and set numerous records during its theatrical run . The Dark Knight appeared on more critics ' top ten lists -LRB- 287 -RRB- than any other film of 2008 with the exception of WALL-E , and more critics -LRB- 77 -RRB- named The Dark Knight the best film of 2008 than any other film released that year . With over $ 1 billion in revenue worldwide , it is the 29th-highest-grossing film of all time , unadjusted for inflation . The film received eight Academy Award nominations ; it won the award for Best Sound Editing and Ledger was posthumously awarded Best Supporting Actor . The Dark Knight Rises , the final film in the trilogy , was released on July 20 , 2012 .
