The Dark Knight, an American superhero film, based on the DC comics character ‘Batman’ has been released at the Liberty Cinema Colombo.

Directed by Christopher Nolan, the film is part of Nolan's 'Batman' film series and a sequel to 2005's 'Batman Begin' and Christian Bale plays the lead role. In this latest Batman series, the film focuses on Batman's fight against a new villain, the Joker (Heath Ledger) and his relationships with district attorney Harvey Dent (Aaron Eckhart) and his old friend and love interest assistant D.A. Rachel Dawes (Maggie Gyllenhaal).

The film begins with the Joker robbing a Mob-owned bank with his accomplices, whom he tricks into killing each other before killing the last one himself. That night, a trio of Batman impersonators interrupts a meeting between mobsters and the Scarecrow. The real Batman appears and apprehends all of the criminals and impostors, but suffers injuries. This leads him to re-design the bat suit. Batman and Lieutenant James Gordon contemplate including new district attorney Harvey Dent in their plan to eradicate the Mob, as he could be the public hero Batman cannot be. While hosting a fundraiser for Dent, Wayne discovers that the new D.A. is dating Rachel Dawes.

When Mob bosses meet to discuss Batman, Gordon, and Dent, a Chinese mobster accountant, Lau, informs the gang leaders he has hidden their money to pre-empt a plan Gordon has hatched to seize the mobsters' funds. The Joker arrives unexpectedly, offering to kill Batman for half of their money, but the offer is refused. After Batman successfully abducts Lau in Hong Kong and delivers him to the Gotham City police, the mobsters agree to hire the Joker. The Joker tells Gotham that if Batman does not turn himself in to the police and publicly reveal his identity, people will die each day. Public officials, including Commissioner Gillian B. Loeb and the judge presiding over the Mob trials, are among the murdered. Wayne decides to reveal himself. Before he can, Dent announces that he is Batman and is arrested, as part of a plan to draw the Joker out of hiding. The Joker attempts to ambush the police convoy carrying Dent, but Batman and Gordon intervene and arrest him. Gordon is appointed Commissioner.

At the police station, Batman interrogates the Joker, who reveals that Dawes and Dent have been captured by corrupt police and placed in warehouses rigged with explosives on opposite sides of the city; they are far enough apart that Batman cannot save them both. Batman leaves to save Dawes, while Gordon and the police head after Dent. With the help of a bomb planted at the police station, the Joker escapes with Lau. Having been deceived by the Joker, Batman arrives at Dent's location in time to save him, but the left side of Dent's face is disfigured in the explosion. Gordon does not arrive in time to save Dawes and she is killed. In the hospital, Dent is driven to madness over the loss of Dawes. The Joker frees Dent from the hospital and convinces him to exact revenge on the corrupt cops and mobsters responsible, as well as Batman and Gordon.

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.
