You sound so surprised that I get the impression that you heard Nolan is doing ALL, or nearly all, of his shooting in daylight. Is that what you heard? Or only that he's doing a fair amount of it in the daytime?

After all, there were several daytime scenes in "The Dark Knight" -- such as the big bank robbery at the start, and the Joker's later attack on Gotham General -- and the fact that those things were happening while the sun was up didn't seem to hurt the movie any.
