Batman Movies News and Updates has translated an interview with The Dark Knight director Christopher Nolan and producer Charles Roven from Kino.de which included these bits (minor spoilers):
– Batman will go to Hong Kong for some kind of “gangster hunting”, but Roven doesn’t say why Batman travels to Hong Kong.
– The IMAX preview with I Am Legend is the first five minutes of the film.
– “The whole thing is not ‘Joker Begins’, because we did not tell how the Joker became what he is,” says Nolan. “During these five minutes it is shown how the the small crook becomes the most-dreaded gangster of the city – it is more like “The Rise of the Joker.”
– Batman’s new mask will have white lenses on the eyes when he turns on the Bat-sonar detection.
The Dark Knight hits theaters on July 18, 2008.
