We know that Christopher Nolan is currently on a worldwide tour to find the perfect locations for The Dark Knight Rises. Today BOF offers a few details on where else he may be looking. According to their source, Nolan would like to film in in the U.K., Los Angeles, Detroit, New York, and someplace else outside of the US. Chicago is missing from this list, and I’d be shocked if they didn’t go back there. Chicago has been used for Gotham in both Batman Begins and The Dark Knight.
