IGN.com attended "An Evening With Christopher Nolan" in Hollywood, where the director touched briefly upon the upcoming Batman Begins sequel, The Dark Knight:

IGN got the chance to ask Chris Nolan if The Dark Knight would delve further into the themes established in Batman Begins, specifically the idea of justice vs. revenge and the exploration of Bruce Wayne's father issues.

"I haven't finished the script yet. I'm supposed to be doing it right now," Nolan admitted, sparking laughter from the crowd. "It does, absolutely. It's a pretty direct continuation of where the last film left off, and the last scene of Batman Begins suggests a strong direction we wanted to take the story in. It absolutely carries on with a lot of the thematic concerns and hopefully takes it someplace new."

When we asked if District Attorney Harvey Dent - a.k.a. Batman's future nemesis Two-Face - would indeed be in the film, Nolan replied, "I don't want to go into too many specifics. Yes, he is."

IGN caught up with Nolan as he was exiting the event and asked if Dent had been cast. "Not yet." Would that actor be an American, an Aussie or a Brit? "You'll see," Nolan promised.
