The Dark Knight (Blu-ray disc)

Director Christopher Nolan's sequel to his own 'Batman Begins' sees Gotham's avenging angel squaring-up to a new kid on the block - psychotic prankster, the Joker (Heath Ledger, in the role that won him a posthumous Oscar for Best Supporting Actor). In the space of a year, Batman (Christian Bale), aided by Commissioner Gordon (Gary Oldman) and new District Attorney Harvey Dent (Aaron Eckhart), has managed to rid Gotham's streets of the organised crime gangs that once ravaged the city. Things seem to be looking up, although on the personal front, Bruce Wayne discovers he has a rival in his affections for main squeeze Rachel Dawes (Maggie Gyllenhaal) in the shape of the new D.A., who, as a political climber, likes to keep his cards close to his chest. But just when the authorities think they're finally making progress in their fight against crime, the appearance on the streets of a sinister new figure, with a demented grin and a passion for chaos, causes panic among the good people of Gotham, and leads to a battle of wits between Batman and the Joker which threatens to get extremely personal.
