The Dark Knight is one my favourite movies. Batman raises the stakes in his war on crime. With the help of Lieutenant Jim Gordon and District Attorney Harvey Dent, Batman sets out to dismantle the remaining criminal organizations that plague the city streets. The partnership proves to be effective, but they soon find themselves prey to a reign of chaos unleashed by a rising criminal mastermind known to the terrified citizens of Gotham as The Joker. Directed by Christopher Nolan and starred by Christian Bale as Bruce Wayne/Batman and the late Heath Ledger as the legendary Joker, Aaron Eckhart as Harvey Dent/Two-Face in this 2008 movie. The Dark Knight is a 2008 superhero film directed, produced and co-written by Christopher Nolan. Based on the DC Comics character Batman, the film is part of Nolan's Batman film series and a sequel to 2005's Batman Begins.Nolan's inspiration for the film was the Joker's comic book debut in 1940, and the 1996 series The Long Halloween, which retold Two-Face's origin. In addition elements of Steve Englehart and Marshall Rogers' Dark Detective miniseries as well as the unpublished follow-up were reportedly cannibalised along with other elements of Batman mythology for the story. The Dark Knight was filmed primarily in Chicago, as well as in several other locations in the US, the UK, and Hong Kong. Nolan used an IMAX camera to film some sequences, including the Joker's first appearance in the film. On January 22, 2008, some months after he had completed filming on The Dark Knight and six months before the film's release, Heath Ledger died from a toxic combination of prescription drugs, leading to intense attention from the press and movie-going public. Warner Bros. had initially created a viral marketing campaign for The Dark Knight, developing promotional websites and trailers highlighting screen shots of Ledger as the Joker, but after Ledger's death, the studio refocused its promotional campaign. The Dark Knight was released on July 16, 2008 in Australia, on July 18, 2008 in North America, and on July 24, 2008 in the United Kingdom. The film received critical acclaim, and set numerous records during its theatrical run; it is currently one of only three films to have earned more than $500 million at the North American box office.
