Nolan focuses in The Dark Knight on the “idea of escalation,” the way Batman’s dramatic persona, with its violent heroism, calls forth a greater, more creative response from the criminal element. It would be hard to imagine a more compelling embodiment of the escalation of evil in Gotham than what Nolan and actor Heath Ledger have created in the character of The Joker, whose insouciant embrace of chaos eclipses the malevolence of Hannibal Lecter from Silence of the Lambs and John Doe from Se7en. What makes Nolan’s latest film such a success is not, however, Ledger’s compelling presentation of evil, on which critics have focused their attention, but the way in which he uses that character to bring out the depth and complex goodness of the other characters in the film, including Batman.Next, John Carney, perhaps taking the films a bit too seriously, asks if Bruce Wayne's business dealings in Batman Begins and The Dark Knight might actually make him that "better class of criminal" the Joker claims to want (HT Peter Chattaway):
He seems to be a white-collar criminal, engaging in the kind of corporate crimes that attract our real-life two-faced prosecutors. He takes corporate resources to pursue his own interests, uses underhanded means to acquire a majority stake in Wayne Enterprises after encouraging an initial public offering, and intimidates a potential whistle-blower.Finally, since Warner Brothers surely wont be able to pass up a cash-cow of a sequel (since everyone knows the third film in a trilogy is always the best!), check out MTV.com's brief interview with Dark Knight writer David Goyer, who claims he and the Nolan brothers already have a theme and a villain in mind. He's not saying who, but there are plenty of possibilities (but watch out for spoilers if you haven't seen The Dark Knight yet).
